Management of Skeletonization of Eutectona machaeralis Through the Release of the Indigenous Egg Parasitoid Trichogramma

The biological control method provides an environmentally friendly alternative to conventional chemical pesticides, reducing the reliance on harmful chemicals and fostering the development of more integrated and sustainable pest management approaches. This study presents strong evidence that releasing the native egg parasitoid Trichogramma chilonis at a rate of 1.25 lakh/ha effectively controlled the populations of major insect pest, the teak defoliator, in both natural forest ecosystems and teak plantations. The release of Trichogramma chilonis significantly diminished the extent of defoliation caused by the pest and lowered larval infestation rates, which are known to affect the health and productivity of teak trees negatively.
