الگوی تخم‌گذاری کنه شکارگر Neoseiulus californicus (Acari: Phytoseiidae) در حضور مواد فرار دریافت شده از کنه تارتن دو لکه‌ای، کنه شکارگر هم‌گونه و تریپس غربی گل

The predatory mite, Neoseiulus californicus (McGregor) (Acari: Phytoseiidae), is one of the effective predators of mite pests such as Tetranychus urticae Koch (Acari: Tetranychidae) and pest insect, the western flower thrips Franklinella occidentalis (Pergande) (Thysanoptera: Thripidae). In this research, the oviposition pattern of the predatory mite on the strawberry leaves (Gavita cultivar) was studied in the presence of volatile from the spider mite adults or conspecific predatory mite or the western flower thrips larvae. Two discs of strawberry leaves are separated in a Petri dish to a distance of one cm apart. We placed 30 spider mite eggs as prey in a disc and in another disc, it was placed 30 spider mite adults or 30 predatory mite adults or 30 the western flower thrips larvae. The number and location of predatory mite eggs on leaflets were determined per 8 hours. The results showed that the numbers of predatory mite eggs were significant different in presence of each prey (spider mite or flower thrips) or conspecific predatory mite. The predatory mite that received the volatile from spider mites laid the most egg numbers. The distance between the first and second eggs laid by the predatory mite that received the conspecific volatiles, was higher than the others. The least distance between eggs laid by the predatory mite was observed for the predatory mite that received the spider mite volatiles. The volatiles from preferential prey (spider mite) were caused the increase of egg numbers. The volatiles from rivals (conspecific predatory mite) due to cannibalism and the volatiles from thrips due to possibility predation on predatory mite eggs are undesirable effect on egg numbers and their distance.
