Temperature-dependent oviposition and nymph performance reveal distinct thermal niches of coexisting planthoppers with similar thresholds for development

PLoS ONE, 2020
The brown planthopper (Nilapavata lugens: BPH) and whitebacked planthopper (Sogatella furcifera: WBPH) co-occur as the principal pests of rice in Asia.

20E biosynthesis gene CYP306A1 confers resistance to imidacloprid in the nymph stage of Bemisia tabaci by detoxification metabolism.

Pest Management Science, 2023
BACKGROUND The differences in physiological level between the immature and mature stage of insect likely contribute to different mechanisms of insecticide resistance. It is well acknowledged that insect 20-hydroxyecdysone (20E) plays an important role in

Characterization and functional analysis of chitinase family genes involved in nymph–adult transition of Sogatella furcifera

Insect Science, 2020
Chitinase degrades chitin in the old epidermis or peritrophic matrix of insects, which ensures normal development and metamorphosis. In our previous work, we comprehensively studied the function of SfCht7 in Sogatella furcifera.

Water quality effects on dragonfly and damselfly nymph communities: A comparison of urban and natural ponds.

Environmental Pollution, 2020
Cities are increasingly using constructed ponds to mitigate flooding and downstream water pollution from urban runoff. As a result, these stormwater ponds can have poor water quality, yet they can also attract wildlife.

The role of Lathyrus sativus flower surface wax in short-range attraction and stimulant for nymph laying by an adult viviparous aphid

Bulletin of entomological research, 2019
Aphis craccivora Koch (Hemiptera: Aphididae) is an important pest of Lathyrus sativus L. plants, and causes retarded plant growth and loss of seed production. The insect sucks cell sap from flowers and lays nymphs on flowers.

BTB domain-containing protein 6 is involved in the development of locust wings during the nymph to adult transition.

International Journal of Biological Macromolecules, 2019
The development of insect wings is a complex process controlled by a series of genes, whereas the mechanism of wing development of orthoptera insects is less frequently reported.
