“…This is higher than that of A. longispinosus feeding on S. nanjingensis (0.335; Zhang et al 1999a). This is very interesting as it shows that A. cucumeris is more efficient than A. longispinosus in converting food (S. nanjingensis) to eggs.…”

The predatory mite Amblyseius cucumeris (Oudemans) was studied in the laboratory to evaluate its potential as a biocontrol agent against the spider mite Schizotetranychus nanjingensis Ma & Yuan, a pest of the moso bamboo in Fujian, China. When fed S. nanjingensis females and eggs, the life cycle of A. cucumeris (developmental time from egg to egg 7.7 days for the first generation and 7.8 days for the second generation) was as long as its life cycle on its normal diet in the laboratory, Tyrophagus putrescentiae (Schrank) (7.8 days) at 27-28 o C. Adult females of A. cucumeris started to lay eggs at the age of 3 days with a daily rate of 1-4 eggs (average of 2.2) over a period of 7-18 days and a total fecundity of 35.8 (14-47) eggs. The number of prey consumed by predators increased with prey density and the number of eggs produced was directly correlated with the number of prey consumed. Female predators consumed twice as many female spider mites as did male and deutonymph predators (6 versus 3 per day at 9 prey per leaf). A. cucumeris females were unable to invade intact webnests of S. nanjingensis but were able to invade and liked to stay and lay eggs in broken nests with existing openings or holes.

Few models concern how environmental variables such as temperature affect community structure. Here, we develop a model of how temperature affects food web connectance, a powerful driver of population dynamics and community structure. We use the Arrhenius equation to add temperature dependence of foraging traits to an existing model of food web structure. The model predicts potentially large temperature effects on connectance. Temperature-sensitive food webs exhibit slopes of up to 0.01 units of connectance per 18C change in temperature. This corresponds to changes in diet breadth of one resource item per 28C (assuming a food web containing 50 species). Less sensitive food webs exhibit slopes down to 0.0005, which corresponds to about one resource item per 408C. Relative sizes of the activation energies of attack rate and handling time determine whether warming increases or decreases connectance. Differences in temperature sensitivity are explained by differences between empirical food webs in the body size distributions of organisms. We conclude that models of temperature effects on community structure and dynamics urgently require considerable development, and also more and better empirical data to parameterize and test them.

Untuk itu, diperlukan adanya penelitian mengenai potensi tungau predator tersebut.…”
