“…Each surviving female was paired with an untreated male of the same age. Each pair of female and male H. axyridis was transferred with a fine brush to a ventilated Petri dish (9 cm diameter, 2 cm high) and fed with sterilized Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs, since this factitious prey has been recognized as an optimal food source for the laboratory rearing of H. axyridis [62]. The E. kuehniella eggs were provided daily, the Petri dishes were cleaned daily, and water was offered to the adults for all the treatments.…”

The harlequin ladybird, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), is a generalist predator and an effective biocontrol agent of various insect pests that has been exploited for the control of aphid pests in the greenhouse and field. However, insecticides are widely used to control aphid pests worldwide and the potential non-target effects of sulfoxaflor and imidacloprid for controlling aphid pests towards this biocontrol agent are little known. Although both sulfoxaflor and imidacloprid act on nicotinic acetylcholine receptors of insects, sulfoxaflor has a novel chemical structure compared with neonicotinoids. We assessed the lethal, sublethal and transgenerational effects of sulfoxaflor and imidacloprid on H. axyridis simultaneously exposed via ingestion of contaminated prey and via residual contact on the host plant at LC20 and LC50 doses estimated for the cotton aphid. Imidacloprid significantly reduced the survival of H. axyridis adults compared to sulfoxaflor at the same lethal concentration against cotton aphid. Both concentrations of imidacloprid and sulfoxaflor reduced the proportion of ovipositing females, and both concentrations of imidacloprid and sulfoxaflor, except LC20 dose of sulfoxaflor, reduced the fecundity and fertility of the parental generation. In the progeny of imidacloprid- and sulfoxaflor-exposed parents, both tested LC50 concentrations significantly decreased the juvenile survival rate, and both concentrations of imidacloprid and sulfoxaflor, except LC20 dose of sulfoxaflor, prolonged the development time. Our findings provide evidence of the negative influence of imidacloprid and sulfoxaflor at low lethal concentrations on the harlequin ladybird and on the progeny of exposed individuals, i.e., transgenerational effects. Hence, these findings stress the importance of optimizing the applications of imidacloprid and sulfoxaflor for the control of aphid pests, aiming at preserving the biocontrol services provided by H. axyridis throughout the integrated pest management approach.

“…Bonte & De Clercq (2008, 2010a report that the reproductive fi tness of O. laevigatus is greater when reared on E. kuehniella eggs than on other artifi cial diets. Many studies have shown that E. kuehniella is a nutritionally superior food for natural enemies (Cocuzza et al, 1997;Specty et al, 2003;De Clercq et al, 2005b;Song et al, 2019;Ricupero et al, 2020). However, there are virtually no studies on the effects of different artifi cial diets on the nutritional quality of E. kuehniella eggs as a food source for species of Orius.…”

“…The success in rearing anthocorids depends on several factors, with the type of food being one of the most crucial (Calixto et al, 2013). E. kuehniella eggs are considered to be a nutritionally high quality food for natural enemies (Cocuzza et al, 1997;Specty et al, 2003;De Clercq et al, 2005b;Song et al, 2019;Ricupero et al, 2020) * Means with same letter in the same column are not statistically signifi cant according to Tukey's HSD test (P < 0.05); ** Diet names were constructed using the initials of the ingredients in each diet.

http://www.eje.cz is possible to mass-rear many species of Lepidoptera (Silhacek & Miller, 1972; Tunçbilek et al., 2009; Kurtuluş et al., 2020). Moreover, eggs are easy to handle and can be prevented from hatching by freezing or UV sterilization (Isenhour & Yeargan, 1981; Samsoe-Petersen et al., 1989). However, in order to facilitate the use of augmentative biological control there is a need to reduce production costs (Bonte & De Clerq, 2010a). The use of E. kuehniella eggs as the main food source in mass-rearing programs of O. laevigatus can increase the production cost (De Clercq et al., 2005a). This has led to a search for cheaper alternatives such as brine shrimp (Artemia sp.) cysts and many artifi cial diets (Arijs & De Clercq, 2001, 2004; De Clercq et al., 2005a). However, the nutritional value of brine shrimp cysts as a source of food is not equal to that of E. kuehniella eggs (Arijs & De Clercq, 2001). On the other hand, developing artifi cial diets for parasitoids and predators can simplify their mass-rearing and make it more cost-effective. However, the nutritional values of artifi cial diets are often inferior to the natural prey or hosts of natural enemies (Grenier, 2009). Many studies show that using alternative diets for feeding several Infl uence of the eggs of Ephestia kuehniella (Lepidoptera: Pyralidae) reared on different diets on the performance of the predatory bug Orius laevigatus (Hemiptera: Anthocoridae

An ultralow amount of sub‐micron spherical SiO2 particles encapsulating 7 wt% crude orange oil (SiliOrange) suspended in water shows surprisingly high insecticidal activity against the cotton leafworm Spodoptera littoralis, and significantly reduces the progeny of cotton aphid Aphis gossypii under laboratory testing conditions. Considering the ease of reproducible preparation of the material and the biocompatible nature of both silica and orange essential oil, these results may open the route to sustainable pest control using new biopesticide water‐based formulations based on sol–gel microencapsulated orange oil.
