Sublethal Effects of Chlorantraniliprole on the Mobility Patterns of Sitophilus spp.: Implications for Pest Management

Insects, Journal Year: 2024, Volume and Issue: 15(6), P. 451 - 451

Chlorantraniliprole, an anthranilic diamide insecticide, has emerged as a promising solution for controlling agricultural pests because of its low mammalian toxicity and selectivity towards non-target organisms. This study investigated the sublethal effects chlorantraniliprole on mobility behavior two significant stored-product pests, Sitophilus oryzae (L.) zeamais Motschulsky (Coleoptera: Curculionidae). Contact assays revealed varying susceptibility levels between species, with S. showing higher sensitivity. Subsequent analysis behavior, both in presence absence food, indicated differences chlorantraniliprole-exposed control groups. While exhibited altered locomotion patterns decreased number food approaches at concentrations, displayed increased walking time reduced immobility periods. These findings highlight importance considering understanding overall impact pests. Further research into long-term consequences exposure is warranted to inform more effective pest management strategies storage.

Abstract Nesidiocoris tenuis (Reuter) (Heteroptera Miridae) is a key biological control agent of the tomato leaf miner Tuta absoluta (Meyrick). However, in cases prey scarcity, this predator switches into phytophagous pest causing ring injuries stems plants. The aim study was to assess side effects dry residues and explore presence target site resistance mutations 10 insecticides, two bioinsecticides, an acaricide fungicide widely applied IPM, on adults N. collected from different regions Crete; Western Eastern island during successive years. Lethal toxicity trials were performed sprayed recorded 2 h, 7 14 days after exposure. At both populations, chlorpyrifos, acetamiprid thiamethoxam moderately harmful at application day slightly application. Only chlorpyrifos maintained its for more than days. All rest tested pesticides (emamectin benzoate, abamectin, chlorantraniliprole+abamectin, chlorantraniliprole, deltamethrin, tebufenpyrad, spinosad, Bacillus thuringiensis var kurstaki , metaflumizone myclobutanil) classified as harmless. Additionally, analysis insecticide sequences indicated absence populations. Overall, our findings illustrate impact 15 their residual mortality rates adults.
