Mesocyclopus scrassus is an insect predatory with environmentally favourable profile. Although malaria in control India, there a possible risk of spread from malarial infected people coming other endemic countries. The probability mosquito vectors several parts necessitates the identification effective and innovative methods. present study focused on identifying biological method for 3rd instar...

The insecticidal activity and receptor binding properties of Bacillus thuringiensis Cry1A toxins towards the forest pests Thaumetopoea pityocampa (processionary moth) and Lymantria monacha (nun moth) were investigated. Cry1Aa, Cry1Ab, and Cry1Ac were highly toxic (corresponding 50% lethal concentration values: 956, 895, and 379 pg/microl, respectively) to first-instar T. pityocampa larvae. Duri...

virulence of blastospores and conidia of the fungus metarhizium anisopliae were investigatedon different instar nymphs and adults of sunn pest, eurygater integriceps. experiments werecarried out through a factorial arrangement in a completely randomized design of threereplications. the bioassays were performed through immersion method. results revealedsignificant differences among virulence of ...

Which factors fundamentally separate infectious disease from other types of predatorprey interactions studied by community ecologists? Could parasitism and predation be combined into a unifying model? After all, parasites and predators both convert energy and nutrients contained in their resources (hosts or prey, respectively) into new biomass and reproductive work. If these focal consumers per...

BACKGROUND & OBJECTIVES The predatory behaviour with reference to the frequency-dependent prey-selection of the water bugs Sphaerodema annulatum Fabricius and S. rusticum Fabricius was studied in the laboratory using the IV instar larvae and pupae of Armigeres subalbatus as prey to ascertain their efficacy as predator of mosquito immatures. METHODS Field collected adult morphs of the water bu...

BACKGROUND Chelisoches morio (Fabricius) (Dermaptera:Chelisochidae) is an important predator of Tirathaba rufivena (Walker) (Lepidoptera:Pyralidae). For better use of the natural enemy, a biological study on C. morio was conducted, particularly its developmental duration, survival, fecundity and sex ratio. And the feeding capacity of C. morio against T. rufivena was also studied under laborator...

The mortality response of lightbrown apple moth, Epiphyas postvittana (Walker), to a controlled atmosphere (CA) cold storage treatment for apricots was investigated. The mean estimated times for 99% mortality (LT99) of 1st and 5th instar larvae inoculated onto apricots and exposed to 1.5% O2, 3% CO2 (CA) at 0°C, were 19.9 ± 0.13 and 22.4 ± 0.24 d, respectively. The treatment time for 50% mortal...
