Sublethal Effects of Atropa belladonna Herbal Extract on Biological Performance of the Two-Spotted Spider Mite Tetranychus urticae Koch (Acari: Tetranychidae)

Abstract

The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) is one of the most important pests of agricultural products. Using chemical pesticides is one of the main methods for its management. Due to undesirable effects of synthetic pesticides, this research was conducted to achieve alternative safe compounds. In this study sublethal effect of Atropa belladonna herbal extract including LC 10 , LC 20 , LC 30 and distilled water were evaluated on biological parameters (such as r, λ, GRR, R 0 and T) of T. urticae. The experiments were done under laboratory condition at 25±2 °C, 60±5% RH, and a photoperiod

Population growth of Tetranychus truncatus (Acari: Tetranychidae) on different drought-tolerant potato cultivars

“…Tetranychus truncatus is difficult to manage due to its host diversity, small size, high fecundity, and strong adaptability (Hong 2012). Consequently, a wide range of synthetic acaricides is continuously used for their management, which not only poses a threat to non-target organisms and human health, but produces resistance to many acaricides (Elzen 2001, Alsendi et al 2018, Dana et al 2018). In order to minimize the use of chemical acaricides, it is imperative to explore an alternative approach for population prediction and management of pest mites (Yan et al 2022).…”
