Therapeutic play in preparing for surgery: behavior of preschool children during the perioperative period

Objective:to describe the behavior of children during the instructional session of therapeutic play (ITP) in the preoperative period and to verify the behavior presented by them during the perioperative period. Methods: Exploratory descriptive study with a quantitative approach, developed in a large private hospital in Sao Paulo, in which the behaviors presented by 30 children between three and five years old, undergoing minor surgery were seen at the hospital during the session of TP and in the surgical center, from admission to awaken from anesthesia. Results: Most children participated in the ITP session (21; 70%), entered the surgical room spontaneously (22; 73.3%) without resisting mother separation (24; 80%), collaborating with the anesthetic procedure (16; 53.3%) and quietly awakening from anesthesia (26; 87%). Conclusion: The use of ITP led the child to understand the surgical procedure, making it less traumatic.


APPROACH AND TREATMENT OF SUICIDAL BEHAVIOR IN THE CLINICAL PRACTICE OF DIFFERENT GROUPS OF HEALTH PROFESSIONALS IN SPAIN: RESULTS OF THE PROJECT EUREGENA.

According to the WHO (World Health Organization) and the European Union, suicide is considered to be a health problem of prime importance and to be one of the principal causes of unnatural death. In Spain, the number of suicides has increased 12% since 2005 . The Research Project “European Regions Enforcing Actions against Suicide (EUREGENAS), funded by the Health Program 2008-2013, has as main objective the description of an integrated model of Mental Health orientated to the prevention of suicide. The differences that allow distinguishing the meaning of prevention in suicide behavior are described and explained through a qualitative methodological strategy and through the creation of discussion groups formed by different groups of health professionals. The results highlight the existing differences between the diverse health professionals who come more in contact with this problem and it shows as well the coincidence of meaning that suicide has to be considered as a priority in the field of health.

Odontopus brevirostris (Hustache, 1936) (Coleoptera, Curculionidae) associated with new host plants belonging to Annona (Annonaceae)

Odontopus brevirostris (Hustache, 1936) feeding on Annona squamosa L., A. cherimola Mill., A. glabra L., and A. muricata L. was observed. The last three host plants are recorded for the first time. The endophitic oviposition occurs in the veins of the ventral surface of the young leaves. The larvae, leaf miners, eat the parenchyma and the adults make small holes in the leaves. The pupation occurs in spherical cocoons protected by a sort of nest (pupation chamber) between the two epidermal layers.

Análise da riqueza da fauna de Braconidae (Hymenoptera, Ichneumonoidea) em remanescentes naturais da Área de Proteção Ambiental (APA) de Descalvado, SP

Analysis of the Braconidae (Hymenoptera: Ichneumonoidea) fauna richness in natural remnants of the Área de Proteção Ambiental (APA) of Descalvado, SP. A survey of the Braconidae fauna on fragmentary natural environments at northeast São Paulo State was conducted using Malaise traps installed in five sites of Área de Proteção Ambiental of Descalvado. A total of 2,262 specimens, representing 22 subfamilies and 94 genera, was sampled throughout a period of sixteen months (from May, 1999 to August, 2000). Biological data were obtained from current literature and behavior patterns of host utilization for the studied fauna, mainly Braconidae which have been successful in control of agricultural insect pests. Statistical analyses indicated that the asymptote of the genera richness has been approached using this sampling method. This is the most complete survey yet available from natural fragmentary areas of the Descalvado Braconidae fauna. Patterns of distribution and richness of the Braconidae genera were established. Cluster Analysis was adopted taking as attribute the number of Braconidae genera.

Comportamento de parasitismo de Trichogramma atopovirilia Oatman & Platner e Trichogramma pretiosum Riley (Hymenoptera, Trichogrammatidae) em posturas de Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae)

The parasitism behavior of Trichogramma atopovirilia and T. pretiosum in Spodoptera frugiperda eggs was evaluated focusing on the features related to the associative learning (alpha conditioning) and recognition of the egg parasitized by the female after the first oviposition experience. Females of both species were observed to recognize the parasitized egg, which takes place after the female drills into the host egg. Following oviposition, 43.59% and 67.53 of females began to feed with an average feeding time of 73.26 ± 11.57 and 64.04 ± 7.05 seconds for T. atopovirilia and T. pretiosum, respectively. The time elapsed in each step of the parasitism behavior significantly decreased after the first oviposition experience, with a trend to stabilize after the 2nd or 3rd egg parasitized, indicating associative learning in these Trichogramma species.

A possible territorial or recognition behavior of Leptoglossus zonatus (Dallas) (Heteroptera, Coreidae)

The coreid Leptoglossus zonatus (Dallas, 1852) is commonly found in corn (Zea mays L.) fields in Brazil, and it has been observed flying and landing on objects or persons near these fields. During January, 1995, this behavior was studied in corn plantations. Results indicated that the bugs concentrated on objects (plastic cylinders traps) introduced into their habitat and that their number increased during the first 24 hs. However, as time passed (8 days), this possible territorial or recognition behavior gradually decreased, and tended to disappear.

Females of Tapinotaspoides, a genus in the oil-collecting bee tribe Tapinotaspidini, collect secretions from non-floral trichomes (Hymenoptera, Apidae)

Harvesting of secretions from non-floral trichomes by females of Tapinotaspoides serraticornis is reported for the first time. The females exhibit a type of mopping behavior using the fringes of long, wavy setae along the posterior margins of their metasomal sterna. Our observations indicated a wide range of host plants used as sources for these secretions, including Waltheria (Sterculiaceae), Tibouchina (Melastomataceae), Sida (Malvaceae), Jacquemontia (Convolvulaceae), and unidentified species of Commelinaceae and Cyperaceae.

Surface swimming behavior of the curculionid Ochetina uniformis Pascoe (Erirhininae, Stenopelmini) and Ludovix fasciatus (Gyllenhal) (Curculioninae, Erodiscini)

The swimming behavior exhibited by specimens of L. fasciatus and O. uniformis was analyzed frame-by-frame with video observation recorded with a digital camera, attached to a stereomicroscope. Adults of O. uniformis, an aquatic insect, swim with all three pairs of legs. During the process of swimming the majority of the abdomen and rostrum remain submerged, part of the fore and hind tibiae remain above the surface, while the mid tibiae remain submerged. The mesothoracic legs, during the power-stroke stage, provide the greatest thrust while the metathoracic legs provide the least forward propulsion. The prothoracic legs, extended forward, help to direct the swimming. The semi-aquatic specie L. fasciatus shows the same swimming style as O. uniformis, that is, with movement of all the three pairs of legs; the mesothoracic legs are responsible for the main propulsion. The insect body remains on the water surface during the process of swimming, while the legs remain submerged. Both species complete a swimming cycle in 0.33 and 0.32 seconds, respectively, with an average speed of 1.38 cm/s and a maximum and minimum swimming duration time of 11.15 and 5.05 minutes, respectively, for L. fasciatus. The swimming behavior exhibited by O. uniformis and L. fasciatus corresponds to the style known as a breast strokelike maneuver. This is the first record of this kind of swimming for both species here observed and increases to seven the number of genera of Curculionidae exhibiting this behavior.

Improvement of a test-chamber for behavioral studies on adult females of Aedes aegypti (Linnaeus) (Diptera, Culicidae)

A test-chamber (K&L-Chamber) made of cardboard and acrylic plastic, and consisting in four sections (A, B, C and D) was developed by Klowden & Lea (1978) for Aedes aegypti host-seeking behavior studies. Later, Foster & Lutes (1985) also used an identical chamber to successfully evaluate the efficacy of electronic repellers. It was described here a modified K&L-Chamber for behavioral studies of Ae. aegypti adults. The chamber was made in polystyrene, consisting of three sections (A, B and C) and using a human hand and a fluorescent lamp as stimulus to attract the mosquitoes. The suitability of the present test-chamber was validated assaying 80 replicates and releasing 10 Ae. aegypti females in each replicate. The females were released in the section A and allowed to fly to the section C. A mean of 96.0% (s.e. 0.213) Ae. aegypti females successfully reached section C. The present test-chamber is cheaper and easier to handle and as efficient as K&L-Chamber, when compared to Foster & Lutes (1978) that noticed 93.8% of Ae. aegypti reaching the trap section.

On the immature stages and natural history of Gonioterma exquisita Duckworth (Lepidoptera, Elachistidae, Stenomatinae)

In the present work the natural history and immature stages of Gonioterma exquisita Duckworth, 1964 of the Brazilian cerrado region are described. The caterpillars are external folivorous feeders and present a diet restricted to pubescent-leaved host plants of the genus Byrsonima Rich. (Malpighiaceae). They are solitary caterpillars and they build a hard individual shelter that looks like a planorbid shell, made from silk and frass, covered with trichomes and silk, where they develop until the last larval instar on the host plant, and remain inside it until the adult emergence on herbaceous stratum. The larval development presented eight instars. Egg, larval head capsules, instar duration, pupa, shelter, and behavior are also described. Diapause is mentioned for the first time in this species.

Relationships between host plant architecture and gall abundance and survival

The plant architecture hypothesis predicts that variation in host plant architecture influences insect herbivore community structure, dynamics and performance. In this study we evaluated the effects of Macairea radula (Melastomataceae) architecture on the abundance of galls induced by a moth (Lepidoptera: Gelechiidae). Plant architecture and gall abundance were directly recorded on 58 arbitrarily chosen M. radula host plants in the rainy season of 2006 in an area of Cerrado vegetation, southeastern Brazil. Plant height, dry biomass, number of branches, number of shoots and leaf abundance were used as predicting variables of gall abundance and larval survival. Gall abundance correlated positively with host plant biomass and branch number. Otherwise, no correlation (p > 0.05) was found between gall abundance with shoot number or with the number of leaves/plant. From a total of 124 galls analyzed, 67.7% survived, 14.5% were attacked by parasitoids, while 17.7% died due to unknown causes. Larvae that survived or were parasitized were not influenced by architectural complexity of the host plant. Our results partially corroborate the plant architecture hypothesis, but since parasitism was not related to plant architecture it is argued that bottom-up effects may be more important than top-down effects in controlling the population dynamics of the galling lepidopteran. Because galling insects often decrease plant fitness, the potential of galling insects in selecting for less architectural complex plants is discussed.

First record of Anastrepha parishi Stone (Diptera, Tephritidae) and its host in Brazil

Anastrepha parishi Stone, 1942 was reared in fruits of Oenocarpus bacaba Martius, 1823 (Arecaceae) collected in Pracuúba, State of Amapá. This is the first record of an Anastrepha species in a native species of Arecaceae.

Selection of artificial hosts for oviposition by wild Anastrepha obliqua (Macquart) (Diptera, Tephritidae): influence of adult food and effect of experience

Several factors influence the selection of oviposition substrates by insects. The aim of the present work was to find answers to the following questions related to the oviposition behavior of Anastrepha obliqua. Can carbohydrates (glucose or sucrose) present in the adult diet have influence on the female preference for an oviposition substrate with similar composition? Can the previous experience with a host containing one of mentioned carbohydrates interfere in further selection of oviposition substrates? The results showed that the kind of carbohydrate present in the adult diet did not affect the female preference for an artificial oviposition substrate, neither when it was presented by itself nor in combination with brewer's yeast. The effect of experience in the oviposition behavior was observed when there was a previous contact with artificial oviposition substrates containing yeast and sucrose. The data are discussed in terms of the behavioral plasticity presented by this species in relation to feeding and oviposition behaviors.

Occurrence, biology and behavior of Liogenys fuscus Blanchard (Insecta, Coleoptera, Scarabaeidae) in Aquidauana, Mato Grosso do Sul, Brazil

Due to the importance of some Pleurosticti Scarabaeidae as agricultural pests allied to information absence on the species that occur in Brazilian Central-West region, on studies occurrence, biology and behavior on this group of scarabs were conducted. Biology and behavioral studies started with Liogenys fuscus Blanchard, 1850 (Melolonthinae), a very common species and were developed in Aquidauana, Mato Grosso do Sul. Adult beetles were collected from light traps from February 2005 to January 2007, at the experimental farm of the Universidade Estadual de Mato Grosso do Sul in Aquidauana (UEMS). In the laboratory adults were placed in plastic containers with soil with sprouts of Brachiaria decumbens Stapf (Poaceae). Eggs were transferred to a climatized chamber at 26 ± 1º C with a 12hourlight, 12hour darkness photoperiod cycle. Adult flight activity occurred in August and in September to December from 06:00 pm to 06:00 am, with the largest number of individuals flying from 07:00 to 10:00 pm. Eggs measured 1 x 1.5 mm and were laid individually or in groups in soil chambers; eggs were initially white and became yellow near hatching. The embryonic period lasted 14.3 days; first, second and third instars lasted 28.5, 48.8, and 68.2 days, respectively. The prepupal period lasted 120.2 days and the prepupa stayed inactive in soil. The mean duration of pupal stage was 27.5 days and the mean longevity of adults was 23.6 days. In laboratory the calling behavior between males and females was observed; copulation lasted, in mean, 25 minutes.

A new host record for Philornis (Diptera, Muscidae)

The crested becard, Pachyramphus validus (Lichtenstein, 1823), is recorded, for the first time, as host of Philornis (Diptera, Muscidae). Subcutaneous larvae were collected in one nestling at the Floresta Nacional de Canela (Rio Grande do Sul, Brazil).
