Two aspects of mating effects on the fecundity, sex ratio and longevity of Neoseiulus cucumeris (Acari: Phytoseiidae) were examined in laboratory experiments: (1) females mated by one, two or three different males (unmated and 3 days old) at 5-day intervals, and (2) females mated by males with different age/mating status (number of females mated previously(More)
Typhlodromus bambusae Ehara is a dominant predator species associated with the spider mite Schizotetrany-chus nanjingensis Ma & Yuan on the giant bamboo (Phyllostachys pubscens) in Fujian, China. In the field, increased densities of T. bambusae were associated with reduced densities of S. nanjingensis on bamboo leaves. Laboratory studies at 22-30¡C on a(More)
Aponychus corpuzae is a pest of bamboo in Fujian, China. The predatory mite Amblyseius longispinosus was explored as a potential biocontrol agent against Ap. corpuzae in a series of experiments on its predation on Ap. corpuzae. The rate of prey consumption (per predator female) increased linearly with temperature from 1.35 at 15°C to 5.22 at 35°C (the(More)
Schizotetranychus nanjingensis Ma & Yuan is a mite pest injurious to the giant bamboo (Phyllostachys pub-scens) in Fujian, China. The predatory mite Amblyseius longispinosus was explored as a potential biocontrol agent against S. nanjingensis in a series of experiments. Functional response experiments at six different temperatures showed that handling time(More)
Three species of the genus Schizotetranychus (Acari: Tetranychidae) are recorded and described from the leaves of the moso bamboo (Phyllostaychs pubescens) in Fujian, China. They are Schizotetranychus nanjingensis Ma & Yuan, S. bambusae Reck and S. tenuinidus Zhang & Zhang sp. nov. A key for separating the females of these three species is given. Notes on(More)
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(More)
This paper gives a report of 45 species of mites from the moso bamboo (Phy-llostachys pubescens) in Fujian province, China. They belong to 23 genera in 9 families. Some of the Tetranychidae (e.g. Aponychus copuzae Rimando and Schizotetranychus nanjingensis Ma et Yuan) and Eriophyidae (e.g. Aculus bambusae Kuang), either alone or in mixed populations, cause(More)
There is an important difference between cannibalism between unrelated individuals and between a mother and its offspring, because the former can be defined as a form of intraspecific competition, but the latter affects the inclusive fitness of individuals. Many examples of cannibalism have been reported in predacious phytoseiid mites. Furthermore, sib(More)
