Morphology of the head and frontal gland in neotropical Nasutitermitinae (Isoptera, Termitidae)

The Nasutitermitinae species are the most diverse and derived of the Isoptera. The phylogeny of this subfamily has been a point of divergence. In an attempt to solve this problem, we propose the use of the morphological features of the head, frontal gland and its associated muscles as phylogenetic characters in some Nasutitermitinae genera. Results found about the head and frontal gland morphology are discussed and suggested to be used in future systematic studies of termites.

FRONTAL GLAND DEHISCENCE IN THE BRAZILIAN TERMITE SERRITERMES-SERRIFER (ISOPTERA, SERRITERMITIDAE)

The primary function of the soldier caste in the Isoptera is the defense of the termite society. The simplest defense is mechanical with oversized mandibles. Besides the mandibles, some termite soldiers use exocrine glands as a means of chemical defense. These glands produce substances which are toxic and/or repellent to termites enemies. Here we report the only case in the Neotropical fauna of dehiscence of the frontal gland in the soldier caste of the Brazilian termite, Serritermes serrifer (Bates).

CORPORA-ALLATA IN FEMALES OF NEOPONERA-VILLOSA ANTS (HYMENOPTERA FORMICIDAE) - RELATIONS WITH OVARIAN DEVELOPMENT

In female ants of the species Neoponera villosa the corpora allata are paired structures located dorsolaterally to the esophagus (Camargo-Mathias and Caetano, 1991). In the present study the glandular volume of the corpora allata was estimated and the activity of the glands was compared with the ovarian development. In the workers there was a relation between activity of these glands and ovaries in stages 0 to IV. In workers, with ovaries at stage V (maximum development) there was a smaller activity of the corpora allata. Another increasing activity was found in workers with ovaries at stage VII.In the queens, mainly those which were mated, whose ovaries were always fully developed, the volume of the corpora allata was smaller than those of the workers.

Produção e qualidade de raiz tuberosa de cultivares de batata-doce no Oeste do Paraná

The objective of this work was to evaluate sweet potato cultivars with starch processing capability, on two cultivation periods, in the western region of Parana (Brazil). Sweet potato was grown at Marechal Candido Rondon, Parana State (24 degrees 33'40 '' S and 54 degrees 4'12 '' W), at a mean annual temperature between 14 and 28 degrees C. The experiment was designed in complete randomized blocks, in a factorial scheme of 4 cultivars (CNPH 003, CNPH 004, Brazlandia Roxa, and Brazlandia Rosada) and 2 cultivation periods (115 and 183 days), with four repetitions. The evaluated parameters were the root productivities (t ha(-1)) and the physical and chemical root composition (humidity, pH, acidity, starch, total soluble sugars and fibers). Data was submitted to all analysis of variance (Anova) and the means were compared by the Tukey test at 5% of probability, Results indicated that sweet potato yield at the cultivars was higher during the 183 day cultivation period (average of 9.14 t ha(-1)) than during the 115 day cultivation period (average of 4.25 t ha(-1)). Thus the CNPH 003 cultivar seems to be a better indication for starch extraction, due to the lowest fiber content in the root, the driest mass content and the largest yield of starch per area.

Qualidade de pitaias de polpa branca armazenadas em diferentes temperaturas

The aim of this paper was to evaluate the effect of storage temperature on the quality of red pitaya of pulp white, produced in Itajobi city, São Paulo state. The pitayas were stored at room temperature, (21-27 degrees C with 44-63% de UR), at 18 +/- 1 degrees C, with 86-92% RH), 13 +/- 1 degrees C, with 85-90% RH and at 8 +/- 1 degrees C, with 85-95% RH. The quality was monitored during storage time through the parameters: fresh weight loss titleble acidity; soluble solids contents; vitamin C, external appearance, pH and fruit firmness. Through the results obtained may be concluded that the temperature at 8 +/- 1 degrees C it was proportioned the small fresh weight loss; the acidity, soluble solids, pH and fruit firmness were influenced by the storage temperature and storage time, but the temperature at 8 +/- 1 degrees C it was that occasioned the small change theses parameters. In general, it can be concluded that the temperature at 8 +/- 1 degrees C it was the best to maintenance the quality of pitaya fruit.

Effect of drying method on the sorption isotherms and isosteric heat of persimmon pulp powder

Moisture equilibrium data of persimmon pulp powders with 50% maltodextrin (dry basis) obtained with different drying methods were determined at 20, 30, 40 and 50 degrees C. The spray-dryer gave a dry product with a higher adsorption capacity than the other methods. The vacuum- and freeze-dried products had the same adsorption capacity. The highest isosteric heat of sorption was observed for powders produced by spray-drying. The isokinetic temperature (T(B)) calculated for persimmon pulp powder obtained by vacuum-, spray- and freeze-drying were 541.4 K, 616.3 K, 513.2 K, respectively. The sorption process was spontaneous and enthalpy controlled.

Desempenho do irrigâmetro no manejo da água de irrigação na cultura do feijoeiro

In this work, the aim was to evaluate the performance of Irrigameter in the management of the irrigation water, led in the culture of the bean plant, comparatively to the use of the methods standard of stove, tensiometers, Bouyoucos, automatic meteorological station and pan Class A. Irrigameter was adjusted to the soil characteristics, culture of the bean and irrigation equipment to confection the management ruler. For direct estimation of the evapotranspiration of the culture of the bean plant in your development stadiums, Irrigameter operated inside with heights of the levels of water of the evaporatorio same to 2, 3 and 5 cm, corresponding to the stadiums of initial development, vegetative development and flowering, respectively. The humidity obtained by the standard method of stove it was adopted as reference in the comparisons of the irrigation depth. Irrigameter can be used in the management of the irrigation to determine the consumption of water directly for a culture, in any development stadium; the methods that estimate the evapotranspiration of the culture overestimated the irrigation depth recommended by the standard method of stove, happening behavior contrary with the ones that determines the current humidity of the soil.

Transplante ovariano: aplicações na reprodução de animais domésticos, silvestres e humanos

Ovarian transplantation constitutes a technique in which one ovary or part of this is transferred from a donor to recipients that may be the same individual, other recipient of the same specie or no, near or far from the original anatomical site. This review covers important concepts for the elucidation of the main events of folliculogenesis and follicular maturation as well as the applications of ovarian transplantation and prospects of this technique in the breeding of domestic animals, wildlife and humans. Other studies are still necessary to better understanding of the events regarding to the ovarian development, interactions between donor and receptor tissues, their site of transplantation as well as individuals and involved species.
