Biochemical and molecular characterization of chlorantraniliprole resistance in Spodoptera littoralis (Lepidoptera: Noctuidae)

Lethal and Sublethal Effects of Cyantraniliprole on the Biology and Metabolic Enzyme Activities of Two Lepidopteran Pests, Spodoptera littoralis and Agrotis ipsilon, and A Generalist Predator, Chrysoperla carnea (Neuroptera: Chrysopidae)

“…In addition, these enzymes are one of the adaptation mechanisms that enhance the insect’s metabolic capacity to counteract pesticides [ 71 ]. Thus, the competence of insects to detoxify is reflected by the reaction of detoxification enzymes to insecticides [ 17 ]. The exposure to lethal and sublethal concentrations (LC 50 and LC 15 ) of cyantraniliprole induced the activity of detoxification enzymes in both S. littoralis and A. ipsilon compared to the control group.…”

“…These enzymes can remove toxins and detoxify insecticides [ 82 ]. Therefore, several studies elucidated the role of these enzymes on lepidopteran insect pests [ 17 , 22 , 39 , 62 ], which suggests the possibility of discovering new insecticidals that act by interfering with metabolic-mediated enzymes in insects [ 83 ].…”

“…Noctuid moths are the most important agricultural pests globally and include species capable of adapting to new climatic or ecological situations, such as cotton leafworm, Spodoptera littoralis [Boisduval, 1833], and black cutworm, Agrotis ipsilon [Hufnagel, 1766] [ 11 ]. Unfortunately, both insects have developed resistance to conventional insecticides, including organophosphates, carbamates, and pyrethroids [ 12 , 13 , 14 ], as well as to several newer insecticides [ 15 , 16 , 17 ]. S. littoralis is a highly polyphagous and destructive pest that attacks a wide range of economically important crops throughout the world and causes yield losses of up to 50%, typically due to larval foraging activity [ 18 , 19 ].…”

Toxicological, biological, and biochemical impacts of the egyptian lavender (Lavandula multifida L.) essential oil on two lepidopteran pests

“…The cotton leafworm, S. littoralis, a major pest in Egypt, has developed significant resistance to a range of synthetic insecticides (Swelam et al 2022) including organophosphates, pyrethroids, and insect growth regulators (Ismail 2023). Field strains have even shown resistance to newer insecticides like chlorantraniliprole, spinetoram, and emamectin benzoate (Fouad et al 2022;Moustafa et al 2024). Additionally, the black cutworm, A. ipsilon, exhibited similar resistance patterns due to intensive insecticide use (Moustafa et al 2022).…”
