A Mucin-Like Protein Is Essential for Oviposition in Nilaparvata lugens [PDF]

open access: yesFrontiers in Physiology, 2019
Mucins play a variety of roles; for example, in vertebrates, mucins lubricate epithelial surfaces and protect tissue from physical and biological damage, however, knowledge of insect mucins is limited. Here, we identified an eggshell-related mucin-like protein, NlESMuc, in the brown planthopper (BPH), Nilaparvata lugens.

Impact of Abamectin on Anagrus nilaparvatae, An Egg Parasitoid of Nilaparvata lugens

open access: yesJurnal Perlindungan Tanaman Indonesia, 2018
Anagrus nilaparvatae (Hymenoptera: Mymaridae) is an egg parasitoid potential for controlling the major pests on rice, the brown planthopper (Nilaparvata lugens [Hemiptera: Delphacidae]).Abamectin is one of insecticides registered for N. lugens. The research was aimed to investigate the impact of contact application of abamectin on the parasitism level ...

Influences of chlorpyrifos on antioxidant enzyme activities of Nilaparvata lugens

open access: yesEcotoxicology and Environmental Safety, 2013
The brown planthoppers (Nilaparvata lugens, BPH) resistant to chlorpyrifos were selected in laboratory for eight generations. In the full course, the successive changes of activities of SOD, CAT and POD were analyzed. The analyses revealed that increasing of LD50 value was parallel to increasing of SOD, CAT, and POD, all of which increased gradually ...

The Metarhizium anisopliae Strains Expressing dsRNA of the NlCHSA Enhance Virulence to the Brown Planthopper Nilaparvata lugens

open access: yesAgriculture, 2022
Metarhizium anisopliae is a broad-spectrum entomopathogenic fungus with large-scale applications in pest control; however, its slow-killing action is a limiting factor. To enhance fungal virulence, we constructed transgenic M.

The effect of migration on transmission of Wolbachia in Nilaparvata lugens.

open access: yesMathematical biosciences and engineering : MBE, 2023
Brown planthopper Nilaparvata lugens, which can transmit rice ragged stunt virus, is a serious and damaging pest to rice plants. Rice plants can protect themselves from the associated diseases of N.lugens by either suppressing or replacing N.lugens by releasing N.lugens infected by a special strain of Wolbachia wStri.
