The times of oviposition are affected little by the use of a night lighting program. Egg shell weight is not changed by the time of oviposition. Egg weight, shell percentage and it's color vary according to the time of oviposition. The egg characteristics have not been affected by the use of night lighting. Night lighting reduces the percentage of eggs downgraded, in particular reducing by 37 %...

In this study, we tested for the presence and efÞcacy of hygienic behavior by Cape honey bees in South Africa and European honey bees, Apis mellifera L. (Hymenoptera: Apidae), of mixed origin in the United States toward Aethina tumida Murray (Coleoptera: Nitidulidae) eggs oviposited in sealed bee brood. We looked for colony differences in removal rates of brood in cells with cappings perforated...

The phantom midge, Chaoborus, is a dipteran, the larvae of which occur in many freshwater habitats and are known to be vulnerable to predation by fish. The hypothesis was tested that ovipositing imagines of Chaoborus use chemical cues to detect predatory fish and avoid depositing eggs into waterbodies containing fish kairomones. The experimental setup consisted of cages with two small water-fil...
