Reproduction by female mosquitoes is dependent on energy resources but modulated by hormones. Our study focused on blood-meal-dependent, anautogenous Aedes aegypti and autogenous Ochlerotatus atropalpus that rely on larval-derived nutrient stores to develop eggs. To determine how larval nutrition affects the endocrinology of egg development in these females, we manipulated the quantity of larva...

abstract more than %90 of natural silk in world is produced by means of mulberry silkworm (bombyx mori l.). therefore, it is important that we recognize and collect mulberry varieties which have high quantity and quality leaf performance. for this purpose, an experiment was conducted with five mulberry varieties (kenmochi, kairyonase, ichinose, shinichinose and local varieties) during two seaso...

Blowflies utilize discrete and ephemeral breeding sites for larval nutrition. After the exhaustion of food, larvae begin dispersing in search of sites to pupate or additional food sources, a process referred as postfeeding larval dispersal. Some of the most important aspects of this process were investigated in the blowfly Chrysomya albiceps, employing a circular arena to allow radial dispersio...

We review key ecological and behavioral mechanisms under­ lying the origin and maintenance of larval sociality in the Lepidoptera. Using communication contexts of group defense, cohesion and recruitment as a framework we relate social complexity among gregarious caterpilla~ to three panerns of foraging: patch-restricted, nomadic, and central-place. A review ofthe incidence oflarval gregarious­ ...

Nutrition is the important physiological process, which plays a prime role in the growth and in turn it affects the productivity of the silkworm. The supplementation of different materials along with mulberry leaves to silkworm results higher yield because the production of quality silk mainly depends on larval nutrition. The influence of antibiotic on growth and development of silkworm larva a...

BACKGROUND Animals are chronically infected by benign and beneficial microorganisms that generally promote animal health through their effects on the nutrition, immune function and other physiological systems of the host. Insight into the host-microbial interactions can be obtained by comparing the traits of animals experimentally deprived of their microbiota and untreated animals. Drosophila m...

Nitrogen availability from dietary protein can have profound effects on the physiology and evolutionary ecology of insect herbivores. While many studies consider the effects of nutrition on consumption and gross body composition of protein and other important nutrients, few consider partitioning to storage for future use. I used chemically defined artificial diets to quantitatively manipulate t...

Enormous data are available on trade, breeding and larval rearing, nutritional and growth studies and aquarium keeping of the ornamental invertebrates from other countries. In India, studies on ornamental invertebrates are not available. The studies related with the biodiversity of ornamental invertebrates are not available from global level. This paper reviewed the research work on marine orna...

Larval therapy is a biological 'dressing' for chronic ulcers which is used for debridement, to initiate healing and to reduce bacteria and unpleasant odour. One condition for being able to employ larval therapy is access to disinfected larvae of good quality. We therefore started rearing Lucilia sericata larvae in 1998. Rearing necrophagous larvae in a hospital setting makes it essential to con...
