Sublethal Effects of Chitosan-O-Arginine, a Chitosan Based Insecticidal Compound against Green Lacewing Chrysoperla zastrowi sillemi (Esben-Petersen)

The widespread application of synthetic chemicals leads to the unintended negative impact non-target organisms both directly or indirectly, as these can infiltrate new environments, disrupting established ecological niches. Laboratory experiments explored effects sublethal doses Cs-O-Arg third instar grubs Chrysoperla zastrowi sillemi when fed with treated and untreated larvae diamondback moth (DBM). results showed that C. grub was P. xylostella at LC25, LC35 LC45 concentrations, there 6.67 per cent mortality C all after 48 72 hours exposure. but, (LC35 LC45) were xylostella, only 3.33 10.00 grubs, respectively. Whereas, caused 33.33 provided DBM feed, whereas treatment LC25 concentrations resulted in highest pupation percentage (76.67%) adult emergence rate (73.33%) same concentration. Chitosan derivative insecticide causes a mild adverse on survival economically significant insect predator sillemi, which hold valuable implications for guiding decisions regarding compatible utilization insecticides alongside other natural predators within integrated pest management strategies.
