Item Effect of food, growth and body lipid contents on the susceptibility of tribolium castaneum herbst to toxicity of insecticides(Kerala Agricultural University, 1975) Visalakshy, A; Nair, M R G KThe growth index and weight of Tribolium castaneum were the highest when reared on wheat 4- 5% yeast followed in the descending order by those of insects reared on groundnut oil cake, gingelly oil cake, wheat and coconut oil cake. There was no correlation between the LD 50 values of parathion and endrin on the adults T castaneum on the one hand and the growth index and weight of the insects on (he other. There was positive correlation between the LD 50 values of parathion and the body lipid contents of 7\ castaneum while there was no such correlations in the case of endrin.Item On the effect of phorate on germination of cowpea seeds and phytotoxicity to the seedlings(Kerala Agricultural University, 1978) Visalakshy, A; Nair, M R G KItem Effect of granular insecticides on nodulation, rhizosphere microflora and growth characteristics of cowpea(Kerala Agricultural University, 1978) Visalakshy, A; Santhakumari, K; George Koshy; Nair, M R G KStudies conducted to assess the effect of ten insecticide granules on nodulation, rhizosphere microflora and growth characteristics of cowpea showed that carbofuran, carbaryl and quinalphos increased the nodules significantly. An increase in size of nodules was also observed by all the insecticides except quinalphos. Carbofuran, carbaryl and chlorodimeiorm increased the plant height. Weight of roots was enhanced by carbofuran and MIPC. The fungal and bacterial population is influenced variously by the different insecticides both in the rhizosphere and non-rhizosphere soil, whereas the actinomycetes population was not affected.Item Residues of fenthion, quinalphos and malathion in paddy grains following surface treatment of gunny bags(Kerala Agricultural University, 1986) Ambika Devi, D; Mohandas, N; Visalakshy, AItem Gametocidal action of insecticides on rice pollen(Kerala Agricultural University, 1969) Visalakshy, A; Nair, M R G K
