RESEARCH EXPERIENCE
PhD Project title: “Studies on Insect-Associated mites of West Bengal.”
PhD Project Description:
The examination over 1050 specimens of insects representing 11 orders collected from 11 districts of West Bengal, India revealed the occurrence of a total of 47 species of mites belonging to 15 families, 23 genera under 3 orders. As per their nature of association with insects, it was found that 22 species were phoretic, 20 parasitic and 5 were predatory in nature. This also included 15 species which are new to science. Along with providing full descriptions, illustrations, collection records, distribution etc. the taxonomic keys of all the taxonomic categories were also given. The thesis also embodied an exhaustive review of literature highlighting the taxonomic work done and focusing their importance as bio-control agents.
Among the mite species included in the thesis, there was one species, Hemipteroseius indicus (Fam. Otopheidomenidae) which was found to be good bio-control agent of Red cotton bug, Dysdercus koenigii. The life cycle study of that species in two controlled temperatures, viz. 19° Celsius and 32 ° Celsius, were worked out. It was found that life cycle was completed at shorter time at 32° Celsius and took longer time at 19° Celsius. Irrespective of temperatures, there was no significant difference in sex ratio and it was found that the females had longer longevity compared to that of males. The observations compared the traits like longevity; survivorships, fecundity etc. and those were highly correlated to maximize the reproductive success and thereby increasing the fitness at the individual and population levels. The construction of life table indicated that reproductive potentiality (Ro = 16.57) at 32° Celsius than at 19° Celsius (Ro = 4.90). Variation was also there in case of intrinsic rate of increase and so also was there in age specific survival rate. The age specific production productively was lowest at 168 hours.
The biological information generated through this study would prove valuable in utilizing this predator in biological control programme.
In the preliminary laboratory experiment conducted for control of D. koenigii with the predatory mite H. indicus, the functional response of the predator-prey interaction was worked out. It was found that the lag of time between release of the mites and commencement of their activities, found to be due to adaptations of the mites with the experimental environment. The study also had shown that modeling of data pertaining to predatory efficiency of H. indicus on D. koenigii at different permutation-combination levels would enable to find out suitable control strategy for management of red cotton bug, an important cotton pest in India.
The laboratory study made for control of D. koenigii by H. indicus had opened a new vista proving potentiality of insect associated mites for control of agriculturally important insect pests and had thrown new light for taking up further study towards working out its functional and numerical responses of these predatory mites for its better utilization in biological control work.
