The oviposition preference of predatory insect, orius laevigatus (fieber, 1860) (hemiptera: anthocoridae), on different succulent plants

Orius laevigatus (Fieber 1860) (Hemiptera: Anthocoridae) is a commercially used predator against soft-bodied pests in greenhouses. Many researchers have done studies on oviposition preference and hatching rate of O. laevigatus which are essential components for the mass-rearing studies of biocontrol agents. In addition, the effects of succulent plants and their potential to use for mass-rearing of O. laevigatus have not fully examined. This study has been done to determine the most suitable host plant for the oviposition preference of O. laevigatus at laboratory conditons between the year 2021 and 2022. No-choice and choice experiments were conducted for the five different succulent plants (Sedum nussbaumerianum Bitter, Kalanchoe daigremontiana Raym.-Hamet H.Perrier, Kalanchoe blossfeldiana Poelln. (Saxifragales: Crassulaceae), Senecio barbertonicus Klatt. (Asterales: Asteraceae) and Aptenia cordifolia (L.f.) N.E.Br. (Caryophyllales: Aizoaceae) at 25ºC ± 2.
