EFFICIENCY OF THE PREDATORY MITE, CHEYLETUS MALACCENSIS OUDEMANS ON Tetranychus cucurbitacearum (SAYED) (ACARI: CHEYLETIDAE & TETRANYCHIDAE) [PDF]
Journal of Productivity and Development, 2016 Developmental time, consumption rate and fecundity of Cheyletus malaccensis Oudemans were studied on different stages (eggs, immatures and adults) of Tetranychus cucurbitacearum (Sayed)at laboratory conditions, 32±2°C and 50±10% R.H.

Is only the first mating effective for females in the Kanzawa spider mite, Tetranychus kanzawai (Acari: Tetranychidae)? [PDF]
, 2008 Although only the first mating is effective for females in Tetranychus urticae (Acari: Tetranychidae), it remains unclear whether this is also true for closely related species, such as T. kanzawai.

Inter-specific crosses between Tetranychus urticae Koch and Tetranychus kanzawai Kishida.
Japanese journal of applied entomology and zoology, 1987 Tetranychus属の近縁な2種のハダニ,ナミハダニT. urticae KOCHとカンザワハダニT. kanzawai KISHIDA間で交雑実験を行い,2種間の生殖的隔離を調べた。交尾は異種間でも見られたが,異種間の交尾では挿入行動が頻繁に中断され,同種間の交尾に比べて交尾時間にはペアー間でばらつきが大きく,また平均交尾時間が短くなった。種間交雑ではF1雑種はまったく形成されなかった。また,最初に他種の雄と交尾をした後,次に同種の雄と再交尾した場合,同種と1回だけ交尾したものと比べてF1のふ化率,幼若虫期生存率に有意差はみられず,異種間の交尾は,同種間の交尾・受精にまったく影響を与えなかった。このように,ナミハダニとカンザワハダニの2種間には完全な前交配的隔離が存在することが明らかであった。

Plant, Cell &Environment, EarlyView.ABSTRACT With climate change, abiotic and biotic stresses such as drought and herbivory are predicted to further diminish agricultural productivity. Soybean (Glycine max [L.] Merrill), a crop of global economic importance, is vulnerable to both. However, the interactive effects of drought and herbivory on soybeans haven't been explored, especially ...

Twospotted Spider Mite, Tetranychus urticae Koch (Arachnida: Acari: Tetranychidae)
EDIS, 2003 The twospotted spider mite, Tetranychus urticae Koch, has been controversial in its taxonomic placement. About 60 synonyms included under this species have compounded the controversy.

Plant, Cell &Environment, EarlyView.ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Mite populations on grapes: Effect of sulfur dust treatments on predatory mites and red spider mite
California Agriculture, 1950 The annual rise and fall of populations of the Pacific mite—Tetranychus pacificus McG—and the Willamette mite— Tetranychus willamettei McG—on grapes has puzzled growers and entomologists for years.

Semina: Ciências Agrárias, 2015 Species of the Tetranychus genus feed on plant tissues, which reduces the rate of photosynthesis and can lead to the death of plant tissues. As a result, considerable production losses are caused by these arthropods.

Physiological Entomology, EarlyView.We investigated maternal effects in Schizotetranychus brevisetosus (Tetranychidae), where females oviposit summer and winter eggs in response to photoperiod on evergreen hosts. Developmental rates of immature individuals increased linearly from 15°C to 35°C, but winter and summer eggs developed faster at low and high temperatures, respectively ...
