Mites of <i>Schizotetranychus</i> (Acari: Tetranychidae) from moso bamboo in Fujian, China

Abstract

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 the biology of these mites are also provided.

Observations on the life history of <i>Schizotetranychus bambusae</i> Reck (Acari: Tetranychidae) infesting bamboo leaves in Fujian, China

“…Recently, it was reported as being the major pest species on moso bamboo (Phyllostaychs pubescens) in Sichuan Province, southwest China . Three species of the genus Schizotetranychus (Acari: Tetranychidae) commonly occur on the leaves of moso bamboo in Fujian: Schizotetranychus nanjingensis Ma & Yuan, S. bambusae and S. tenuinidus Zhang & Zhang in Zhang et al (2000). While the latter two are found only on moso bamboo, S. bambusae has a broader host range.…”

Schizotetranychus-like spider mites (Acari, Prostigmata, Tetranychidae) - revisited, new combinations and a key to groups of Schizotetranychus based on females

“…Saito et al (2004) reinstated the genus Stigmaeopsis Banks based on the presence of only six setiform structures on the palp tarsus of females and males (2 simple setae, 3 eupathidia and one solenidion), while there are seven of these structures (three simple setae + ...) in Schizotetranychus. The seven species now recognized as Stigmaeopsis, S. celarius Banks, S. longus (Saito, 1990), S. miscanthi (Saito, 1990), S. nanjingensis (Ma and Yuan, 1980), S. tenuinidus (Zhang and Zhang, 2000), S. saharai Saito andMori, 2004 andS. takahashi Saito andMori, 2004 are also characterized by the position of the dorsocentral hysterosomal setae: the bases of the pairs of setae e1, d1 and c1 are progressively wider apart than the bases of f1 setae, that is, hypothetical lines connecting their bases form a V shaped pattern (these lines are parallell in the other Tetranychini, including Schizotetranychus), as pointed out by Saito et al (2004).…”

Larvae and protonymphs of the predator <i>Typhlodromus bambusae</i> (Acari: Phytoseiidae) attacked and killed by adult males of their prey, <i>Schizotetranychus nanjingensis</i> (Acari: Tetranychidae)

“…Petri dishes (diameter 12 cm) were used as platforms for observing mites in the laboratory (Zhang et al 2000). Moso bamboo leaves were placed on a piece of filter paper soaked with water in the dish.…”

“…Schizotetranychus nanjingensis Ma & Yuan, a major pest of the moso bamboo (Phyllostaychs pubescens) in southern China, is also a member of the Schizotetranychus celarius group and is believed to be closely related to S. longus (Zhang et al 2000). Females of this species cooperatively construct nests with a very dense web roofing on the underside of bamboo leaves.…”
