Characterization of Spodoptera littoralis (Lepidoptera: Noctuidae) resistance to indoxacarb: inheritance mode, realized heritability, and fitness costs.

Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) is a major economic pest attacking a variety of crops in Egypt and other Mediterranean countries. S.

Physiological Function of RDL1 and RDL2 Subunits of the Ionotropic GABA Receptor in the with the CRISPR/Cas9 System .

In insect ionotropic γ-aminobutyric acid receptor (iGABAR) subunits, only resistance to dieldrin (RDL) can be individually and functionally expressed . In lepidopteran, two to three RDL subtypes are identified; however, their physiological roles have not been distinguished . In this study, Rdl1 and Rdl2 of were individually knocked out using CRISPR/Cas9, respectively.

The Comparative Toxicity, Biochemical and Physiological Impacts of Chlorantraniliprole and Indoxacarb on (Lepidoptera: Noctuidae).

Background: The cabbage moth, is a polyphagous pest that attacks several crops. Here, the sublethal and lethal effects of chlorantraniliprole and indoxacarb were investigated on the developmental stages, detoxification enzymes, reproductive activity, calling behavior, peripheral physiology, and pheromone titer of Methods: To assess pesticide effects, the second instar larvae were maintained for 24 h on a semi-artificial diet containing insecticides at their LC, LC, and LC concentrations.

Results: was more susceptible to chlorantraniliprole (LC = 0.

Flupyradifurone induces transgenerational hormesis effects in the cowpea aphid, Aphis craccivora.

With low-dose stimulation and high-dose inhibition, insecticide-induced hormesis, a biphasic phenomenon, can contribute to pest resurgence. The cowpea aphid, Aphis craccivora (Koch) (Homoptera: Aphididae), is a vital insect that infests legume crops. Its hormesis of flupyradifurone has not been previously established.

Toxicity of Fipronil and Emamectin Benzoate and Their Mixtures Against Cotton Leafworm, Spodoptera littoralis (Lepidoptera: Noctuidae) With Relation to GABA Content.

Fipronil and emamectin benzoate (EMB) are effective insecticides for controlling cotton leafworm, Spodoptera littoralis. Fipronil works by blocking gamma-amino butyric acid (GABA) gated chloride. In contrast, EMB is activating GABA transporters.
