Neoseiulus bicaudus (Wainstein) (Acari: Phytoseiidae) is a generalist predatory mite that consumes several pest species, including Tetranychus turkestani (Ugarov et Nikolskii) (Acari: Tetranychidae) in the Xinjiang Uygur Autonomous Region. The release numbers of predatory mites are based on the populations of target pests and their ability to control them. Populations of T. turkestani and T. truncatus Ehara (Acari: Tetranychidae) often coexist and damage many crops. To determine whether the presence of the non-target prey T. truncatus affects the ability of N. bicaudus to control the target prey T. turkestani. The study evaluated the predation rate and functional response of N. bicaudus to 4 stages of T. turkestani in the presence of T. truncatus. The consumption of T. turkestani by N. bicaudus gradually decreased as the proportion of T. truncatus increased. The functional response of N. bicaudus to T. turkestani was not changed when T. truncatus was presented, which was consistent with a type II response. The attack rate of N. bicaudus on the egg, larva, and nymph of T. turkestani was significantly decreased and the handling time of N. bicaudus on T. turkestani was significantly extended when T. truncatus was presented. The preference index showed that the preference of N. bicaudus for eggs and female adults of T. turkestani decreased with increasing density of T. turkestani in the same proportion as T. truncatus. The presence of T. truncatus can negatively affect the predation of T. turkestani by N. bicaudus. We suggest that the number of N. bicaudus released to control T. turkestani should be increased when T. truncatus coexist.

Neoseiulus bicaudus Wainstein (Acari: Phytoseiidae) is a beneficial predatory mite to control spider mites. To evaluate the suitable storage conditions of N. bicaudus, the survival of adult females was observed under different combinations of low temperature (3, 6, 9, or 12°C), food (F) or no food (NF), and high (H) or low (L) humidity conditions for 7, 14, 21, 28, and 35 d. Predator mites’ longevity and survival time of 50% and 80% individuals (ST50,80) were measured and compared between treatments. After storage, female and male living mites were paired at 26°C. The progeny parameters were evaluated after storage. Results revealed that survival rate decreased as storage temperature decreased. At 3 and 6°C, fewer mites survived after 28 d. At 9°C, ~50% of the females survived in the FH treatment after 35 d. At 12°C, >80% survived 7–35 d in the FH treatment. Moreover, longevity and ST50,80 were significantly greater in the FH treatment than in the FL or NFH treatments at 3, 9, and 12°C. The highest longevity (48.6 ± 3.7 d) and ST50 (51.6 d) occurred at 12°C in the FH treatment. There was no effect on progeny hatching or survival rates when adults were stored at 9 or 12°C for 28 d. At 9°C, the total preadult development time was 4.20–5.25 d. At 12°C, the total development time was 4.87–4.93 d and there was no significant difference between the storage treatment and control group. These results demonstrated that N. bicaudus females can be successfully stored at 9°C for ~21 d and 12°C for ~28 d with little effect on adult survival or progeny parameters.

Neoseiulus bicaudus (Wainstein), a species of Neoseiulus Hughes (Acari: Phytoseiidae), was collected at Ili in the Xinjiang Uyghur Autonomous Region of China in July 2013. As Neoseiulus species are valuable predator mites, N. bicaudus could be used for biocontrol of some small pests like spider mites, whitefly, and thrips. Tetranychus turkestani (Ugarov et Nikolskii) is the main spider mite affecting agriculture and forestry in Xinjiang. The development rate and reproductive biology of N. bicaudus feeding on T. turkestani were studied at six constant temperatures: 18 ºC, 22 ºC, 26 ºC, 29 ºC, 32 ºC, and 35 ºC. The duration of the egg, larva, protonymph, total immature, and pre-oviposition stages all decreased as temperatures increased from 18 ºC to 32 ºC and then increased slightly as temperatures increased from 32 ºC to 35 ºC. The mean generation time (6.95 days) and the shortest time for the population to double (1.70 days) were observed at 35 ºC. The intrinsic rate of natural increase (r m ) and the finite rate of increase (λ) both were larger as temperature increased, reaching their maxima at 35 ºC. The net reproductive rate (R 0 = 34.60) also reached a maximum at 26 ºC. The maximum daily fecundity (2.55 eggs/day/female) and the maximum daily female fecundity (1.69female eggs/day/female) were both observed at 26 ºC. The results showed that N. bicaudus could complete its development at the six temperatures used in this study. Both the developmental duration as well as the time needed for the population to double decreased as temperature increased. As temperature increased, the duration of the oviposition period first increased and then decreased. The optimal development and reproduction temperature of N. bicaudus preying on T. turkestani is approximately 26 ºC.
