“…The prey stage preference of N. cucumeris in this study was different from previous studies in which N. cucumeris preferred 1st instars over eggs of Tetranychus urticae Koch or F. occidentalis (Shipp & Whitfield 1991;Croft et al 2004). Different nutritional benefits of each prey (Popov & Kondryakov 2008;Blackwood et al 2001), morphological traits such as long dorsal shield setae (Croft et al 2004) and the size and activity of each predatory species (Sabelis 1985) were reported to play roles in prey stage preferences of predatory mites. Nevertheless, since both D. citri nymphs and adults can acquire and transmit the HLB pathogen, preference by the predator for the egg stage of D. citri should be considered desirable for HLB management because the elimination of D. citri eggs reduces the probability of disease transmission.…”

“…Ambient temperature is one of the most important factors influencing the rates of development, survival, reproduction, and predation of N. cucumeris (Popov and Kondryakov 2008;Shipp et al 1996;Van Driesche et al 2006). The favorable temperature range for this species is 21-28°C with relative humidity conditions of 80 % (Zhao 2014).…”

In order to explore the role of heat shock proteins (Hsps) during thermal stress and development in the predatory mite Neoseiulus cucumeris (Oudemans), we cloned and characterized five full-length Hsp genes. We investigated the expression levels of these genes by quantitative real-time PCR. The five genes characterized here were NcHsp90, NcHsp75, NcHsp70, NcHsp60, and NcHsp40. These Hsps showed high sequence conservation and had greatest identity with heat shock proteins of Metaseiulus occidentalis and other mite and insect species. All five NcHsp genes showed changes in their levels of expression during development. Higher levels of expression were observed in adult females than in adult males, but there were no significant changes between pre-oviposition and post-oviposition stages in the females. NcHsp90, NcHsp75, and NcHsp70 expression levels were up-regulated after a heat shock, and the increases in NcHsp75 and NcHsp70 expression levels were maintained for at least 3 h. Up-regulation of NcHsp60 and NcHsp40 was not detected after 1 h at a high temperature (35-45 °C); however, a significant down-regulation was observed after 3 h heat exposure at 35 °C and 3 h recovery at 25 °C. Cold shock treatment (-5 to 15 °C) for 1 h did not acute elicit changes in the expression levels of any of the genes. At 5 °C, the expression levels of NcHsp90 significantly increased after 6 or 24 h exposure compared to the levels after 1 h exposure. Thus, expression of Hsp genes in N. cucumeris reflected developmental changes, sexual difference, and variable induced response to thermal stress. Increased expression of Hsps might protect N. cucumeris individuals under extreme temperature conditions. Therefore, it may be possible to enhance the thermal tolerance of commercially available N. cucumeris using temperature acclimation. Treatment at 35 °C should be suitable for such acclimation.

“…Blackwood et al 2001 reported that adult females of phytoseiied predator P. persimilis preferred T. urticae eggs over the larvae. In contrast, Popov and Kondryakov (2008) reported that adult females of P. persimilis consumed more males of Tetranychus spp. than the eggs or females.…”

INCIDENCE OF THE PREDATORY MITES INHABITING GRAPEVINES IN SHARKIA GOVERNORATE, EGYPT AND FUNCTIONAL RESPONSE OF Euseius metwallyi IN PREYING Tetranychus urticae (ACARI : PHYTOSEIIDAE : TETRANYCHIDAE)

A survey conducted recently in Sharkia governorate, Egypt indicated the presences of 11 species of predatory mites on grapevines. These species belong to families Phytoseiidae (8 species), Cunaxidae (one species), Cheyletidae (one species), Stigmaeidae (one species). Frequency occurrence of the collected species was discussed. A logistic regression of the proportion of prey consumed as a function of initial prey density was conducted to identify functional response types. Nonlinear least-squares regression and the random predator equation were used to estimate attack rates and handling times. Overall, adult females E. metwallyi exhibited a type 2 functional response to T. urticae. Whereas, attack rate and handling time of E. metwallyi recorded 0.10 , 0.28 and 0.07 and 0.99 , 1.47 and 4.59 when offering eggs , males , females of T. urticae, respectively. Generally, these results indicated that the predator E. metwallyi may be considered as biocontrol agent against the two-spotted spider T. urticae.
