Parental exposure to heat waves improves offspring reproductive investment in Tetranychus urticae (Acari: Tetranychidae), but not in its predator, Phytoseiulus persimilis (Acari: Phytoseiidae)

Abstract: The more frequent and intense occurrence of heat waves is a challenge for arthropods because their unpredictable incidence requires fast adaptations by the exposed individuals. Phenotypic plasticity within and across generations might be a solution to cope with the detrimental effects of heat waves, especially for fast‐developing, small arthropods with limited dispersal abilities. Therefore, we studied whether severe heat may affect the reproduction of a pest species, the spider mite Tetranychus urticae, and i… Show more

“…During the scorching summer months, natural ecosystems and controlled agricultural environments contend with soaring temperatures, which provide ideal conditions for the proliferation of T. urticae populations [7]. Elevated temperatures not only result in more giant adult female mites and increased egg production but also diminish the size of individual eggs [8]. The remarkable adaptability of T. urticae to such high-temperature stressors inflicts significant damage to crops, leading to substantial economic losses and jeopardizing food security.…”
