Dispersion Statistics and Sample Size Estimates for Tetranychus kanzawai (Acari: Tetranychidae) on Mulberry
No full textDispersion indices were calculated for Tetranychus kanzawai Kishida in groves of mulberry, Morns alba (L.), in Taiwan. These indices indicated a clumped distribution for the surveyed population range of T. kanzawai: 0.53–96.5 mites per leaf. However, the X2 goodness-of-fit test generally rejected the negative binomial model among trees, but accepted it within trees. The level of aggregation varied with the population density of T. kanzawai and among mulberry groves. The dispersal of spider mites is discussed as a factor affecting this parameter. Optimal sample size is estimated for various densities of T. kanzawai and error margins on the assumption of Taylor's power law and mean crowding-mean regression
Aponychus 壹新種及 A . corpuzae 的重新描述
No full textAponychus mallotus n. sp. was collected from Mallotus paniculatus (Lam.) Muell. Arg. in central Taiwan. Aponychus corpuzae Rimando collected from bamboo is redescribed with measurements on dorsal setal length and leg chaetotaxy observed by this author.

Contribution to the Know-Ledge of the Genus Paraphytoseius Swirski and Shechter (Acarina:Phytoseiidae) in Taiwan
No full textControl of phytoseiids in a spider mite mass-rearing system (Acari: Phytoseiidae, Tetranychidae)
No full textPhytoseiid mites which contaminated the spider mite colony and interfered with the mass-rearing of spider mites were controlled by dipping in hot water. Immersion for 60 s in water of 50°C killed all stages ofAmblyseius fallacis (Garman),A. womersleyi Schicha andPhytoseiulus persimilis (Athias-Henriot) (Acari: Phytoseiidae). Only approximately 0.3% of theA. womersleyi eggs hatched, and this seems negligible. The populations ofTetranychus kanzawai Kishida andT. urticae (Koch) (Acari: Tetranychidae) were reduced. However, they recovered well. Although this treatment resulted in the withering of some soybean seedlings, the next trifoliate leaf to be produced was normal. A very satisfactory result was obtained when this technique was applied to the mass-rearing system
