Geographic variation of sex pheromone and mitochondrial DNA in Diatraea saccharalis (Fab., 1794) (Lepidoptera: Crambidae)

(9Z,11E)-hexadecadienal and (Z11)-hexadecenal, the main sex pheromone components of the sugarcane borer, Diatraea saccharalis, were identified and quantified from four Brazilian and one Colombian populations using GC-EAD, GC-MS and GC analyses. Three different ratios were observed, 9:1,6:1, and 3:1. The pheromone concentration for the major component, (9Z,11E)-hexadecadienal, varied from 6.8 ng/gland to 21.9 ng/gland and from 1.7 ng/gland to 6.5 to the minor component, (Z11)-hexadecenal. The 25 D. saccharalis cytochrome oxidase II sequences that were analyzed showed low intra-specific variation and represented only 11 haplotypes, with the most frequent being the one represented by specimens from Sao Paulo, Parana, and Pernambuco states. Specimens from Colombia showed the highest genetic divergence from the others haplotypes studied. Data on the genetic variability among specimens, more than their geographic proximity, were in agreement with data obtained from analyses of the pheromone extracts. Our data demonstrate a variation in pheromone composition and a covariation in haplotypes of the D. saccharalis populations studied. (C) 2010 Elsevier Ltd. All rights reserved.

Can occupational therapy intervention play a part in maintaining independence and quality of life in older people? A randomised controlled trial Jeannine Liddle 1 , 2 , Lyn March 3 , Barbara Carfrae 4 , Terence Finnegan 5 , Jane Druce 6 , Jennifer Schwarz 7 Peter Brooks

The main objective of this study was to see if older people could maintain their quality of life and independence after their homes had been modified and they were using community services as recommended by an occupational therapist. There were 167 study participants aged 69 to 94 years from the Northern Sydney Area, After being assessed at home by an occupational therapist, 105 were randomly allocated to one of two groups, to either have or not have the occupational therapist's recommendations carried out, They were assessed again after six months, A third group did not require any intervention, This group was followed up by telephone and postal questionnaire at six months. The main outcome measures used were the Sickness Impact Profile, the Philadelphia Geriatric Center Morale Scale, the Life Satisfaction Index, assessment of Activities of Daily Living, the Health Assessment Questionnaire and change in residence. After six months there were no difference in outcomes among the three groups. Most study participants remained at a satisfactory level on each measure. Three people had died, One had moved to hostel care and one had moved to a nursing home. A further 14 from the group having no intervention had withdrawn from the study, A secondary objective of this study was to indicate the responsiveness of these outcome measures to change in the short term (over six months) in an elderly population. Twelve-month assessments are in progress and may indicate what to expect from these outcome measures in the medium term.

Reproductive biology of the eastern shovelnose ray, Aptychotrema rostrata (Shaw & Nodder, 1794), from Moreton Bay, Queensland, Australia

The eastern shovelnose ray, Aptychotrema rostrata (Rhinobatidae), is an endemic batoid common to the east coast of Australia. The reproductive cycle was studied in Moreton Bay, south-eastern Queensland, over a 14-month period. Aptychotrema rostrata is an aplacental yolksac viviparous species with an annual, seasonal reproductive cycle in Moreton Bay. Females mature at 54-66 cm total length, and males at 60-68 cm total length. Gravid females were observed during September-November and parturition occurred in November-December. Vitellogenesis does not proceed in parallel with gestation. Ovulation and copulation probably occur during July-September, resulting in a gestational period of 3-5 months. Uterine fecundity ranges from 4 to 18, with a significant positive relationship between uterine fecundity and maternal body length. In mature males, a peak in the proportion of mature spermatocysts in the testes was observed in July, whereas gonadosomatic index peaked in April.

Preferência de Cotesia flavipes (Cameron, 1891) (Hymenoptera: Braconidae) por lagartas de Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) alimentadas com diferentes cultivares de cana-de-açúcar

O objetivo desta pesquisa foi avaliar a preferência do parasitoide Cotesia flavipes (Hymenoptera: Braconidae) por lagartas de Diatraea saccharalis (Lepidoptera: Crambidae), alimentadas com diferentes cultivares de cana-de-açúcar. O experimento foi conduzido em laboratório, em duas condições de alimentação, uma envolvendo lagartas de D. saccharalis, alimentadas em dieta artificial, e, a outra, com lagartas alimentadas em dieta artificial e mantidas temporariamente nos toletes dos cultivares de cana-de-açúcar. Os cultivares utilizados foram: SP80-1842 e SP81-3250, resistentes, e RB855536, suscetível à D. saccharalis. A preferência para oviposição das fêmeas de C. flavipes foi avaliada em testes com e sem chance de escolha, em delineamento inteiramente casualizado, com quatro tratamentos e 15 repetições. Lagartas de D. saccharalis com 19 dias de idade foram oferecidas para fêmeas de C. flavipes, acasaladas e com 24 horas de idade, em ambos os testes. No teste com chance de escolha, utilizou-se um olfatômetro, o qual constou de quatro compartimentos, em cujo centro liberaram-se quatro fêmeas de C. flavipes, enquanto, no teste sem chance de escolha, foram utilizadas placas de Petri, no interior das quais se colocou uma lagarta de D. saccharalis, oriunda das duas condições de alimentação. Nestes testes, foi observada a percentagem de parasitismo e, continua-mente, o comportamento da primeira escolha de fêmeas de C. flavipes, em intervalos de zero a um, um a três, três a cinco, cinco a oito e de oito a dez minutos após as liberações. Lagartas de D. saccharalis, oriundas da alimentação em dieta artificial com colmos triturados dos cultivares, foram igualmente preferidas para atratividade de fêmeas do parasitoide C. flavipes. A percentagem de parasitismo de lagartas de D. saccharalis, criadas com dietas artificiais com colmos dos cultivares SP80-1042 e RB855536, foi igualmente parasitadas por C. flavipes.

O quadrado mágico de Benjamin Franklin

Benjamin Franklin (1706-1790) foi jornalista, cientista, inventor, homem de estado e diplomata. (...) Benjamin Franklin era um entusiasta de quadrados mágicos. Chegou mesmo a criar os seus próprios quadrados. O mais conhecido é o quadrado 8 por 8 apresentado na imagem. Numa carta publicada em 1769, Franklin refere: "Na minha juventude, divertia-me a construir quadrados mágicos, de modo a que a soma dos números de cada linha, de cada coluna e de cada uma das duas diagonais principais fosse sempre a mesma; com o passar do tempo, conseguia criar quadrados mágicos, de tamanho razoável, tão depressa quanto conseguia escrever os números nas suas linhas e colunas; mas, por não estar totalmente satisfeito com estes quadrados, que eram demasiado fáceis, impus a mim mesmo o desafio de construir outro tipo de quadrados mágicos, que apresentassem propriedades mais ricas e que constituíssem, assim, um maior estímulo à curiosidade." Em relação ao quadrado mágico da imagem, são utilizados todos os números naturais, do 1 ao 8x8=64, uma e uma só vez. Além disso, a soma dos números de cada linha e de cada coluna é sempre igual a 260, a constante mágica. Existem muitas outras formas de obter o valor 260 (...)

Preliminary screening of the larvicidal effect of Brevibacillus laterosporus strains against the blowfly Chrysomya megacephala(Fabricius, 1794) (Diptera: Calliphoridae)

AbstractINTRODUCTION: This study evaluated whether different strains of Brevibacillus laterosporus could be used to control larvae of the blowfly Chrysomya megacephala , a pest that affects both human and animal health.METHODS:Mortality rates were recorded after 1-mL suspensions of sporulated cells of 14 different strains of B. laterosporus were added to 2.5g of premixed diet consisting of rotting ground beef fed to first instar larvae of C. megacephala . All bioassays were performed using 10 larvae per strain, with a minimum of three replicates for each bioassay. Larval mortality was recorded daily up to seven days.RESULTS:Strains Bon 707, IGM 16-92, and Shi 3 showed the highest toxicity toward the larvae producing 70.5%, 64.5%, and 51.6% of larval mortality, respectively, which was significantly higher than that in the control group (p < 0.05). In contrast, strains NRS 1642, NRS 661, NRS 590 BL 856, NRS 342, ATCC 6457, Bon 712, and NRS 1247 showed limited or no pathogenic activity against the target larvae.CONCLUSIONS:Our preliminary data indicated that B. laterosporus could be used to develop bioinsecticides against C. megacephala .
