Discovery and characterisation of field resistance to organophosphorus chemicals in a major mite pest, Halotydeus destructor

Abstract

These findings demonstrate the strong evolutionary capability of H. destructor and highlight the need for ongoing resistance surveillance within Australia. © 2017 Society of Chemical Industry.

A cryptic diapause strategy in Halotydeus destructor (Tucker) (Trombidiformes: Penthaleidae) induced by multiple cues

“…In comparison with South African populations, Australian populations have expanded into hotter and drier inland areas and have become more thermoresistant . Pesticide resistance against pyrethroids and organophosphates has also evolved in H. destructor populations in Australia. Although the interactions between these evolutionary changes and diapause induction are unclear in H. destructor , pesticide resistance has been shown to influence photoperiodic diapause in the codling moth, Cydia pomonella , indicating pleiotropic trade‐offs .…”

“…The number of diapause eggs produced by H. destructor dramatically impacts the population size in the following autumn . The first generation of mites can cause serious feeding damage to crop and pasture seedlings because of the synchronicity between the germination of annual plants and the emergence of post‐diapause H. destructor …”

“…5 The first generation of mites can cause serious feeding damage to crop and pasture seedlings because of the synchronicity between the germination of annual plants and the emergence of post-diapause H. destructor. 38,39 To minimize autumn population sizes, a carefully timed chemical spray can be applied before the onset of diapause, as prescribed in a strategy developed in Western Australia based on assessments of 18 field populations. 5 This work suggested diapause induction was best predicted by day length (80.1% of variation explained), followed by the duration of long-term plant growing season (10.4%) and other factors (9.5%).…”

Design, synthesis, insecticidal activity and 3D-QSR study for novel trifluoromethyl pyridine derivatives containing an 1,3,4-oxadiazole moiety

“…2,3 Currently, because of the generation of resistance and cross resistance, the insecticidal effect of phthaldiamides (such as uobendiamide) and traditional organophosphorus pesticides was tapered. [4][5][6][7][8] Thus, the development of insecticidal agent with novel structure is increasingly required.…”

Novel Trifluoromethyl Pyridine Derivatives Bearing a 1,3,4‐Oxadiazole Moiety as Potential Insecticide

“…With the generation of resistance and cross resistance on the harmful pests in agriculture, and the banning use of pesticides with high toxicity and poor environmental compatibility. [1][2][3][4][5][6] The agricultural pests often brought about actual losses in productivity of crops all over the world annually. [7] The development of insecticidal agent with novel structure and mechanism of action increasingly required.…”
