Effects of host plant and temperature on growth and reproduction of the strawberry spider mite Tetranychus turkestani Ugarov & Nikolski (Acari: Tetranychidae)

Abstract

Tetranychus turkestani is a serious pest of cotton, corn, vegetables, fruit trees and forests in Xinjiang. All life stages of T. turkestani were observed using both light and scanning electron microscope. The egg is smooth and spherical. The eupathidial spinnerets of larva and protonymph are different from that of the deutonymph and adult in shape. The spinneret of adult female is obviously thicker and larger than that in male. The palpfemoral seta of adult male is a short, stout, spine-like process. T. turkestani has fourteen pairs of dorsal setae. The number of ventral setae increases regularly in number in each molt. The leg chaetotaxy has a great change from larva to deutonymph.

<p><strong>Effects of temperature on development and reproduction of <em>Neoseiulus bicaudus</em> (Phytoseiidae) feeding on <em>Tetranychus turkestani</em> (Tetranychidae)</strong></p><p><strong><em><br /></em></strong></p>

“…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 same as Gotoh et al (2004). This is consistent with previous observations that insect development rates increase as temperature rise and then slow down when temperatures become too high (Sohrabi & Shishehbor, 2008;Liu, 1986;Yue et al, 2009).…”

Identification of exotic pest and Australian native and naturalised species of Tetranychus (Acari: Tetranychidae)

“…In cotton, T. turkestani thrives during dry warm periods (Canerday & Arant 1964). Life history data was presented by Carey and Bradley (1982), Sohrabi and Shishehbor (2008) and Yuan et al (2008). Bailly et al (2004) demonstrated that the large host range of this species (175 spp.…”

TEMPERATURE DEPENDENT LIFE PARAMETERS AND PREDATORY POTENTIAL OF A STIGMAEID MITE, Agistemus buntex, CHAUDHRI AGAINST TWO SPOTTED SPIDER MITE, Tetranychus urticae, DUFOUR

“…Agistemus buntex is the most abundant stigmaeid mite species found in the Punjab, Pakistan that consumes different stages of Panonychus citri (McGregor) and Tetranychus urticae (Chaudhri and Akbar, 1985). Temperature affects the development rate of poikilothermic animals as illustrated by (Sohrabi and Shishehbor, 2008;Latifi et al, 2010). Determination of temperature dependent development characteristics is critical for population prediction, development time, survivorship, migration and dormancy of the predatory organisms (Aghdam, 2008).…”
