Fatty acids for insect species remain constant: A case study of pink bollworm, Pectinophora gossypiella (Saunders)

Abstract Pink bollworm, Pectinophora gossypiella (Saunders) originates from South Asia and has spread across major cotton-growing regions. The pest is considered to be the most destructive of economic concern globe. In India, developed resistance dual Bt toxins its concealed feeding nature makes target sites almost inaccessible for insecticide. view this issue, there need identify a suitable alternative management. context, semiochemicals serve as one best eco-friendly options. These chemical substances or mixtures broadcast messages purpose communication. Semiochemicals may released eggs, faecal pellets, tarsal segments, scales, anal tufts and/or any insect components that reduce intra/interspecific competition shared resources such food, mating, oviposition site etc. Accurate identification semiochemical compounds their proportion in natural blends arouse strong behavioural response insects, requires thorough knowledge. Therefore present study, we tried explore chemicals pellets whole-body wash extracts mated female. Seven were identified methanolic extract faecal-pellet samples, namely hexadecanoic acid, 9,12-octadecadienoic 9-octadecenoic acid methyl esters along with stearate. However, only four methyl-esterified forms found common eggs female body extract. This clearly shows remain constant conserved species but role these needs demonstrated.
