Monitoring and Occurrence Prediction of the Migration Population of Helicoverpa armigera (Hübner) Based on Adult Semiochemical Attractants

open access: yesAgronomy
Helicoverpa armigera (Hübner) is a destructive agricultural pest. Facultative migration usually causes regional catastrophes; therefore, developing a simple and easy new technology for the monitoring and early warning of immigrant populations is urgent ...

(R)-(+)-citronellal identified as a female-produced sex pheromone of Aromia bungii Faldermann (Coleoptera: Cerambycidae)

open access: yesEgyptian Journal of Biological Pest Control, 2018
Aromia bungii Faldermann (Coleoptera: Cerambycidae) is an important wood-boring pest of peach, apricot, plum and cherry in China. It is difficult to control it because of the cryptic feeding behaviour of larvae within the bark.

Sex Attractants for Male Lepidoptera

open access: yesAgricultural and Biological Chemistry, 1977
About one hundred of unsaturated long straight chain compounds (C10-C18) containing a terminal hydroxyl or acetoxyl group were synthesized and their attractiveness to male Lepidoptera were tested in various environments. In this screening test, male insects of ninety- three species which belong to fifteen families were attracted specifically.

Gazing Behavior During Mixed-Sex Interactions: Sex and Attractiveness Effects [PDF]

open access: yesArchives of Sexual Behavior, 2009
We investigated to what extent the length of people's gazes during conversations with opposite-sex persons is affected by the physical attractiveness of the partner. Single participants (N = 115) conversed for 5 min with confederates who were rated either as low or high on physical attractiveness.

Semiochemical and Vibrational Cues and Signals Mediating Mate Finding and Courtship in Psylloidea (Hemiptera): A Synthesis

open access: yesInsects, 2014
Mate finding and courtship involve complex interactions that require close coordination between individuals of the opposite gender. Well-organized signalling systems, sometimes involving a combination of signal modalities, are required to convey species ...

Attraction of Adults of Cyclocephala lunulata and Cyclocephala barrerai (Coleoptera: Scarabaeoidea: Melolonthidae) towards Bacteria Volatiles Isolated from Their Genital Chambers

open access: yesMolecules, 2020
In the study of the chemical communication of adults of the Melolonthidae family, bacteria have been observed in the epithelium of the genital chamber; possibly, bacteria are involved in the production of sex attractants in their hosts.

Chemistry of sex attraction. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1995
The chemical communication system used to attract mates involves not only the overt chemical signals but also indirectly a great deal of chemistry in the emitter and receiver. As an example, in emitting female moths, this includes enzymes (and cofactors, mRNA, genes) of the pheromone biosynthetic pathways, hormones (and genes) involved in controlling ...

Laboratory and field evaluation of acetic acid-based lures for male Asian citrus psyllid, Diaphorina citri

open access: yesScientific Reports, 2019
The Asian citrus psyllid (ACP) is a vector of a pathogen associated with greening and thus a major problem in citriculture worldwide. Lures are much needed for improving ACP trapping systems for monitoring populations and surveillance.
