ABSTRACT Green oil‐in‐water (O/W) nanoemulsions incorporating essential oils (EOs) and food‐derived compounds are gaining prominence as biopesticidal platforms that address the growing demand for sustainable agriculture, food safety, and reduced chemical inputs.

Inter-specific crosses between Tetranychus urticae Koch and Tetranychus kanzawai Kishida.
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。

Citrus defense responses against Tetranychus urticae [PDF]
En la presente tesis doctoral se han estudiado los mecanismos de defensa de cítricos frente al ataque de T. urticae a diferentes niveles. En primer lugar se analizaron los mecanismos de defensa directa utilizando dos patrones con diferente nivel de susceptibilidad.

Glufosinate Ammonium Suppresses Tetranychus urticae in Cotton
Twospotted spider mites, Tetranychus urticae, are an important agricultural pest of many field crops worldwide. Insecticides and acaricides play a primary role in controlling T. urticae populations on agricultural crops. Here, we used greenhouse and field applied foliar spray tests and leaf dip bioassays to examine the susceptibility of T.

(A) The predator Phytoseiulus persimilis and its prey Tetranychus urticae were reared under mild or extreme heat waves from egg to adulthood, which resulted in asymmetrical thermal shifts of adult body sizes in favour of prey under extreme heat waves. (B) Single couples of adult predators and prey, reared under mild heat waves interacted at mild heat ...
