A computer model for simulating population dynamics of Lyctocoris campestris (F.), a predator of stored-product insects, was developed using data from the literature and newly collected data for adult longevity and fecundity. Immature development time and survival, adult longevity, fecundity, and cannibalism were simulated. The model was validated at ambient environmental conditions during thre...
BACKGROUND: Statistical analyses in human populations have associated limited food availability during development with increased longevity of next generations. In support, recent findings in Caenorhabditis elegans revealed nutritional effects on transgenerational longevity. OBJECTIVES: In this study we tested the effect of nutrition on longevity of future generations in Drosophila and whether ...
BACKGROUND Previous genetic evidence suggested that the C. elegans TGF-beta Dauer pathway is responsible solely for the regulation of dauer formation, with no role in longevity regulation, whereas the insulin/IGF-1 signaling (IIS) pathway regulates both dauer formation and longevity. RESULTS We have uncovered a significant longevity-regulating activity by the TGF-beta Dauer pathway that is ma...
Regarding the importance and high potential of Encarsia formosa Gahan (Hymenoptera: Aphelinidae) for control of the greenhouse whitefly, Trialeurodes vaporariorum Westwood (Homoptera: Aleyrodidae), the effect of different diets and storage of the parasitoid at low temperatures on its longevity and efficiency was studied. The average longevity of the parasitoid on different diets including honey...
The beet armyworm, Spodoptera exigua, is one of the most important pests of sugar beet in Iran. The aim of this study was to determine the effect of water and nitrogen treatments of sugar beet planton developmental time and fecundity life table parameters of the pest. An experiment was carried out under laboratory conditions (25±2oC, 70±5% R.H. and 12L: 12D) on larvae reared...
