Premises, Amravati Road, Nagpur - 440 033 (India) Helicoverpa armigera is a major pest of many tropical crop plants and a voracious feeder of leaves, developing seeds, fruits or bolls leading to drastic reduction in yield. The efficacy of proteinase inhibitor (PI) from Zizyphus jujuba (ZJ) leaves in retarding the growth of H. armigera larvae and a complete inhibition of digestive and mitochondrial enzymes has been reported. The PI responsible for mortality of H. armigera was found to be a 16.8 kD protein having PI, ²-glucosidase and haemagglutinating activity. https://www.biotech-asia.org/vol3no2/successive-use-of-proteinase-inhibitor-of-zizyphus-jujuba-leaves-for-effective-inhibition-of-helicoverpa-armigera-gut-enzymes-and-larval-growth/ Zizyphus jujuba; proteinase inhibitor; Helicoverpa armigera
