Insecticide resistance status in the whitefly, Bemisia tabaci genetic groups Asia-I, Asia-II-1 and As
The present study is a summary of the current level of the insecticide resistance to selected organophosphates, pyrethroids, and neonicotinoids in seven Indian field populations of Bemisia tabaci genetic groups Asia-I, Asia-II-1, and Asia-II-7. Susceptibility of these populations was varied with Asia-II-7 being the most...
Use of 16S rRNA probes for characterization of gut microflora of silkworm (Bombyx mori L.) breeds
: The gut microflora of silkworm, Bombyx mori L. are associated with various physiological processes besides providing colonization resistance to invading pathogens through production of antimicrobial compounds. Characterisation of beneficial gut microbes finds wide application in commercial sericulture. Culture depende...
1 March 2017 Quantitative Changes of the Carboxylesterase Associated with Pyrethroid Susceptibility i
Carboxylesterase-mediated insecticide resistance was studied in Spodoptera litura Fab with three different populations from Varanasi, Delhi and Sonepat. The level of susceptibility to pyrethroid insecticides (cypermethrin and bifenthrin), activity of carboxylesterase (CarE) and amino acid substitutions in esterase gene...
STORAGE INSECT PESTS AND THEIR DAMAGE SYMPTOMS: AN OVERVIEW
Stored product pests gain access to the grain storage from the standing crop in the field to various stages of grain processing and storage. Although, about one thousand species of insects have been associated with stored products in different parts of the world, a few pests are considered as pests causing severe damage...
Effect of Host Plants on Insecticide Susceptibility and Detoxification Enzymes Activity in Spodoptera
Susceptibility to two insecticides (profenophos and cypermethrin) as influenced by host plants viz., cauliflower, soybean and castor in comparison to artificial diet and changes in detoxification enzymes in tobacco caterpillar, Spodoptera litura were studied under laboratory. In comparison to larvae reared on artificia...
