Description Potential of RNAi in insect pest management
Helicoverpa armigera is an important pest infesting a number of crops of high commercial value leading to huge
economic losses globally. RNA interference (RNAi) is a potent tool for the control of insect pests and towards this
objective, transgenic tomato expressing dsRNA of Juvenile hormone acid methyl transferase (JHAMT) gene of H.
armigera was developed. The H. armigera larvae fed on HaJHAMT tomato leaves led to a severe (90%) down regulation
of the cognate gene expression thus adversely affected the feeding and metamorphosis. Reduction in larval
and pupal weight and inability to undergo complete metamorphosis were observed that led to larval-pupal
intermediates and subsequently affected the eclosion. Thus, JH down regulation is an attractive target due to
specificity to insects and its important role in insect growth and development to engineer insect resistance in
crops using RNAi.
