Abstract

Knowledge of the effects of pesticides on biological control agents is necessary for the successful implementation of integrated pest management programs. Laboratory bioassays were conducted to evaluate the effects of Biomite®, a natural acaricide, on the life table parameters of Neoseiulus californicus McGregor (Acari: Phytoseiidae), as one of the most important natural enemies of Tetranychus urticae Koch (Acari: Tetranychidae) under laboratory conditions at 25 ± 2°C, 65 ± 5% RH and a photoperiod of 16:8 (L:D) h. The raw data were analyzed based on the two-sex life table theory. Biomite® concentrations LC10 and LC20 gradually and significantly reduced the longevity and total life span of both sexes, as well as total fecundity. Besides, concentration LC20 significantly reduced the gross reproductive rate (GRR) and the net reproductive rate (R0). However, the intrinsic rate of increase (r) and the finite rate of increase (λ) were not significantly affected. Thereby, due to an unfavorable shortened in life history characters of N. californicus such as total life span, reproductive periods and biological parameters (such as R0 and GRR), as a consequence of Biomite® treatment, it can be concluded that this acaricide should not be used with N. californicus in integrated pest management programs.

The effects of the abamectin and spirodiclofen mixture on life history and population parameters of Amblyseius swirskii

“…This may be due to the low effect of Envidor on the predatory mite A. swiriskii , which is considered an important biological control factor. A trend, similar to the results obtained on A. swiriskii and N. californicus species of phytoseiid family as well as the target pest of the two-spotted spider mite, was obtained, which indicates the effectiveness of insecticides such as bifenazate, hexythiazox, and thiamethoxam and like Envidor in this research (Havasi et al 2020, 2021a, b). However, no evidence is available regarding the sublethal (LC 5 , LC 15, and LC 25 ) effects of Envidor speed on biological attributes.…”

Toxicological and physiological activity of lemongrass and peppermint essential oils on life-table parameters of Oligonychus mangiferus and its predatory mite, Cydnoseius negevi

“…The LC 50 of the tested essential oils did not affect population parameters of C. negevi such as (r m ), (λ), (R 0 ), (GRR), (T) and (D t ). In line with these ndings, Biomite® had no discernible impact on life table parameters including (r m ) and (λ) of the predatory mite, Neoseiulus californicus (McGregor) (Havasi et al 2020). No signi cant effect of N. crispa, S. hortensis, and A. graveolens essential oils was noticed on A. swirskii population parameters (Ghasemzadeh et al 2022).…”
