“…Adult parasitoids exposed to pesticides suffer increased short-term mortality (Asadi et al 2019;Bayram et al 2010;Cheng et al 2021;Ohta and Takeda, 2015). For example, the pesticide Metomil reduces the survival of Trichogramma pretiosum (Hymenoptera: Trichogrammatidae) eggs, larvae, and pupae by 96%, 91%, and 67%, respectively, with only 5% of parasitoids exposed to pesticides being viable (Bueno et al 2008).…”

Parasitoids are a significant mortality factor in the population dynamics of many arthropods involved in key ecological processes such as herbivore-plant and predator-prey interactions.Parasitoids are therefore widely used in biocontrol programs. Global change phenomena influence these natural and anthropocentric roles of parasitoids and here we review the effects of the main drivers and their interplay. Land use intensification modifies landscape structure and elevates agroecosystem loads of fertilizers and pesticides creating risks for parasitism and loss of biocontrol services. Climate change can affect parasitoids directly, affecting physiology and survival, or indirectly via phenological and other effects (plant chemistry, herbivore-induced plant volatiles HIPVs) on their hosts, endosymbionts and plants. Biological invasions have the potential to modify native host-parasitoid systems and elevate risk of novel pest dynamics, requiring restoration of biocontrol. The interplay between these global change drivers may thus exacerbate the overall risk to parasitism in future agricultural landscapes. To make more accurate predictions, future studies could focus on the impact of interacting global change drivers on parasitoids and the biocontrol services they provide. Moreover, host and parasitoid specificity appear to be a key driver in assessing the effects of global change on parasitoids.

“…46,47 Regardless of the advances in chemical control of C. cephalonica, no information is available on the sublethal effects of phosphine on them. Studies have been conducted on the direct effects of pesticides on different pest insects and parasitoids [48][49][50] including botanical pesticides. 51 Apart from it being a pest insect, C. cephalonica also is widely used as factitious host for mass-rearing several biocontrol agents.…”

BACKGROUNDThe rice moth, Corcyra cephalonica (Stainton) (Lepidoptera: Pyralidae) is a pest of stored grains and widely used as a factitious host during the mass rearing of several natural enemies of crop pests. Hormesis is well‐documented in pest insects, to some extent in natural enemies of pests.RESULTSWe report transgenerational stimulatory effects of the widely used fumigant, phosphine. The study reports the consequences of sublethal, low lethal and median lethal concentrations (LC5, LC25 and LC50) and untreated control for two sequential generations of the species (G1 to G2). In this study, we investigated the life‐history traits, nutrient reserves (protein, lipid and carbohydrate) and larval gut microbiome (using 16 s rRNA V3–V4 metagenomics sequencing) of C. cephalonica. Stimulatory effects were observed for various biological traits of C. cephalonica, notably adult longevity, emergence and increased egg hatchability when exposed to LC5 of phosphine. The total protein, lipid and carbohydrate contents of C. cephalonica also were found to be significantly increased by LC5 in both generations. The microbial diversity of LC5 treated larval gut was higher and found to be different from the rest of the treatments. This is the first report showing hormesis to a fumigant insecticide.CONCLUSIONOur findings increase knowledge on the interaction between hormesis, nutrient reserves and gut bacteria in C. cephalonica exposed to insecticides. Overall, the present study establishes phosphine‐induced hormesis at LC5 in the host C. cephalonica, which might help improve the quality of mass rearing of various natural enemies. © 2023 Society of Chemical Industry.

“…The demography of fig wasp is therefore remarkably changeable even in a very recent period. The demographic studies of wasps usually based on field observation in a relatively short duration focus on the yearly fluctuations of demographic factors (e.g., number, daily survival rates, and sex ratio) (Forouzan et al, 2013;Asadi et al, 2019). For example, the 3-year field experiments (1997)(1998)(1999) in a social wasp species (Polistes fuscatus) (Nadeau and Stamp, 2003), and the observation of a primitively eusocial wasp (Ropalidia fasciata), in Japan began in 1983 (Ito, 1996;Ito and Kasuya, 2005).…”
