“…Control effects of some insecticides against the third or second instar nymphs of mango mealybug Drosicha mangiferae(Green) were once evaluated. 40,41 They found that the selected suspension concentrate of CAP did not show contact toxicity and effective control to Drosicha mangiferae. Different from the mango Drosicha mangiferae, a high reduction rate of pest population (90%) was observed on the ninth day after the first pesticide treatment in our present work, which may be attributed to the combined results of both contact toxicity and stomach toxicity.…”

Chitosan has emerged as a promising biopolymer carrier for the sustained release of pesticides owing to its good biocompatibility, biodegradability, and bioactivity. In this work, a controlled-release formulation of insecticide chlorantraniliprole was fabricated through coprecipitation-based synchronous encapsulation with chitosan, where the optimum preparation conditions, storage stability, deposition behavior, and application potential were investigated. Preparation of optimization data from response surface methodology showed high correlation coefficient (R 2) of 0.9875 and adjusted coefficient (R adj 2) of 0.9715. The resulting formulation displayed good loading content of 28.39%, high encapsulation efficiency of 75.71%, and good storage stability. Compared with the commercial suspension concentrate, the formulation exhibited better wettability and retention behaviors on plant leaves. Excitingly, effective control against one species of mealybug genus Paraputo Laing (outside the killing spectrum) on the Hippeastrum reticulatum plant was successfully achieved by spraying the controlled-release formulation at different time intervals. This work indicates the good potential of the developed formulation in expanding the application scope of chlorantraniliprole, which shows a new strategy for sustainable pest management.
