Identification of a General Odorant Receptor for Repellents in the Asian Corn Borer Ostrinia furnacalis

open access: yesFrontiers in Physiology, 2020
Attractants and repellents are considered to be an environment-friendly approach for pest management. Odorant receptors (ORs), which are located on the dendritic membranes of olfactory sensory neurons in insects, are essential genes for recognizing ...

Differences in Emergence Date and Size Between the Sexes of \u3ci\u3eMalacosoma Americanum\u3c/i\u3e the Eastern Tent Caterpillar (Lepidoptera: Lasiocampidae) [PDF]

open access: yes, 2017
Malacosoma americanum males were smaller and began to pupate earlier than females. Since the sexes spent the same amount of time as pupae, males also emerged earlier. The adaptive significance of these results is discussed.

Attraction of Acorn-Infesting \u3ci\u3eCydia Latiferreana\u3c/i\u3e (Lepidoptera: Tortricidae) to Pheromone-Baited Traps [PDF]

open access: yes, 2017
Males of acorn-infesting Cydia latiferreana are attracted to an equilibrium mixture of the four isomers of 8, 10-dodecadien-l-ol acetate, the virgin female-produced pheromone. Trap height relative to the height of trees in which traps are placed seems to

Research Progress of Insect Odorant Receptors

open access: yesGuangdong nongye kexue, 2022
For insects, olfaction is an important signal input source for their behavioral perception. There are many kinds of proteins involved in the process of odor recognition, and they play a leading role in regulating feeding, swarming, mating, oviposition ...

Behavioral traits and sexual recognition: multiple signaling in the reproductive behavior of Cyclocephala distincta (Melolonthidae, Cyclocephalini) [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2021
Night-foraging cyclocephaline scarab beetles rely on floral structures of specific plant hosts for food and shelter, as well as mating sites. Although the role of floral fragrances as long-range attractants in these interactions has been elucidated, the ...

Evaluation of textile substrates for dispensing synthetic attractants for malaria mosquitoes [PDF]

open access: yes, 2014
Background: The full-scale impact of odour-baited technology on the surveillance, sampling and control of vectors of infectious diseases is partly limited by the lack of methods for the efficient and sustainable dispensing of attractants.

ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

open access: yes, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Function and Characterization Analysis of BodoOBP8 from Bradysia odoriphaga (Diptera: Sciaridae) in the Recognition of Plant Volatiles and Sex Pheromones

open access: yesInsects, 2021
The belowground pest Bradysia odoriphaga (Diptera: Sciaridae) has a sophisticated and sensitive olfactory system to detect semiochemical signals from the surrounding environment. In particular, odorant-binding proteins (OBPs) are crucial in capturing and
