Agricultural and Forest Entomology, EarlyView.Spirodiclofen resistance levels in B. yothersi varied geographically across the Brazilian citrus belt, with higher resistance in the central region. Sublethal effects included reduced oviposition, increased non‐viable eggs and disrupted female reproduction.

Hairy Roadblock: Stem Trichomes Impede Herbivore Movement in a Species and Instar‐Dependent Manner
Journal of Applied Entomology, EarlyView.ABSTRACT Plants have evolved to deploy a vast set of defence mechanisms against insect herbivores, including physical barriers like leaf trichomes with pre and post ingestive effects. Yet, the role of stem trichomes in plant‐herbivore interactions, particularly mobility dynamics, is poorly understood.

Agronomía Colombiana, 1987 Some important ecological topics about Tetranychus cinnabarinus (Boisduval.) (Acari: Tetranychidae) pest management was studied in a comercial crop of carnation Dianthus caryophyllus L. in greenhouse in Suba - Cundinamarca.

Turkish Journal of Agriculture: Food Science and Technology, 2020 Two new spider mites, Tetranychus kanzawai Kishida and Eotetranychus rubiphilus Reck (Trombidiformes: Tetranychidae) were recorded for Turkish phytophagous mite fauna. While E. rubiphilus was obtained from Prunus domestica L.

Bivariate stochastic modeling of functional response with natural mortality [PDF]
, 2010 A correction due to Abbott (1925) is the standard method of dealing with control mortality in insect bioassay to estimate the mortality of an insect conditional on control mortality not having occurred.

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 ...

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.

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 ...
