- Abstract:
- ... Biotechnological techniques allow the investigation of alternatives to outdated chemical insecticides for crop protection; some investigations have focused on the identification of molecules tailored from nature for this purpose. We, herein, describe the negative effects of water-soluble lectin from Moringa oleifera seeds (WSMoL) on Anagasta kuehniella development. The chitin-binding lectin, WSMoL ...

- Abstract:
- ... The coatomer subunit alpha (COPA) and aquaporin 9 (AQ9) genes from the two-spotted spider mite, Tetranychus urticae, were previously determined to exhibit RNA interference (RNAi)-based lethality when their double-stranded RNAs were systemically delivered via multi-unit chambers (Kwon et al., 2016 [8]). In current study, the hairpin RNAs of the COPA and AQ9 were transiently expressed in soybean pla ...

- Abstract:
- ... Fenamiphos is a systematic nematicide-insecticide used extensively for the control of soil nematodes. Fenamiphos and oxidation products have been known to induce water pollution, soil pollution and ecotoxicological effects on aquatic organisms, as well as heath issues. This contaminant can be removed by phytoremediation. Herein, we tested several strategies to improve the effectiveness of this tec ...

- ... The brown planthopper, Nilaparvata lugens, possesses a strong adaptability to extreme temperature and insecticide stresses. Heat shock proteins (Hsps) are highly conserved molecular chaperones and play a pivotal role in response to various environmental stresses in insects. However, little is known about the response of Hsps to stresses in N. lugens. In the present study, an inducible Hsp70 (NlHsp ...

Therefore, these insecticides are ideal for pest control. Ryanodine receptors (RyRs) play a critical role in Ca2+ signaling in muscle and non-muscle cells. In this study, we cloned the complete cDNA (DcRyR) of the RyR from the citrus whitefly, Dial ...
