Abstract
Experiments were conducted to investigate the antifeedant activity of
leaf extracts of Wrightia tinctoria, Murraya koenigii, and Prosopis
juliflora against teak leaf skeletonizer, Eutectona machaeralis
Walk. The study was carried out from August 2021 to July 2022 in the Zoology
laboratory of Tara Government Degree and PG College, Sangareddy (latitude
17.603666° and longitude 78.077221°) above the sea level of 496 meters. In this
experiment, 1% methanol extracts of Wrightia tinctoria Murraya
koenigii leaves and Prosopis juliflora leaves were used. Third
instar larvae of Eutectona machaeralis were collected from the Teak
plants in the college garden and reared in the laboratory. No choice method was
followed. Among the plant extracts tested, Murraya koenigii showed the
highest Antifeedant Index value (90.64 %). AFI values for Wrightia tinctoria
and Prosopis juliflora were 38.22% and 42.28 % respectively. The
experiment indicates that Leaf extracts of Murraya koenigii have high AFI
values.
