Stored product psocids as one of the preys of the predatory mite

Original language description

Cheyletus eruditus is a predator of stored product mites, but preys occasionally also on other srnall arthropods such as psocids of the genera Liposcelis and Lepinotus. Many species of psocids are common stored product pests and they very often occur ingrain together with pest mites.The aim of the present research was to study "predator - prey" relations, i.e. C. eruditus and psocids. Freshly developed fernales of C. eruditus were fed either by eggs, nymphs, rnales or females of Liposcelis decolor in order to study the predators behaviour, sucking time of the prey body and impact on prey population. The results indicate that the predator C. eruditus is able to prey on all developmental stages of the psocid L. decolor.Mean handling time (manipulation and sucking of psocid prey) varies from 24 to 90 minutes in dependence on the prey body size. Depending on predator-prey ratio (1:2,1:5) the population size of psocids was depressed to 11 and 12.5 % of the control population size, respecti

Czech name

Skladištní škůdci jako jedna z forem kořisti predátorských roztočů

Czech description

Ch.eruditus je predátor skladištních roztočů, ale příležitostně se živí i dalšími drobnými členovci, např. pisivkami rodu Liposcelis, které se často vyskytují spolu se škodlivými roztoči. Byl studován vztah predátor ? kořist a bylo zjištěno, že Ch. eruditus je schopen se živit všemi vývojovými stadii pisivky L. decolor (vajíčka, nymfy, dospělci).Průměrný čas manipulace s kořistí a délky sání závisí na velikosti kořisti (24 ? 90 min.).
