“…GC-EAD analyses revealed that females responded to four compounds present in the VOC blends of the different cultivars: two monoterpenes (β-ocimene and sabinene) and two sesquiterpenes (α-farnesene and β-caryophyllene) (Figures 2, 3a). The response to these compounds was confirmed with synthetic compounds [64]. Four females also responded to β-myrcene but only with VOC blends from cv.…”

“…The way that mature insects behave in reaction to volatile substances released by plants differs depending on the gender. Modulations in the peripheral or central neural systems may be the cause of these variations in behavioral reactions [5]. It is interesting to note that ethylacetophenone, an appealing flower volatile, elicited stronger responses in immature than in mature flies of the cabbage root fly, Delia radicum, whereas allyl isothiocyanate, a compound stimulating oviposition behavior, elicited stronger responses in mature than in immature flies.…”

“…These findings are consistent with the behavioural roles of these compounds. Differential antennal sensitivity to behaviorally active chemicals was demonstrated by a number of host-derived compounds that elicited stronger reactions in females than in males and, at least at high doses, stronger responses in mature flies than in immature flies [5].…”

“…Aspects of feeding and mating aggregation formation, insect strategies to locate both hosts and mates, behavioral reproductive isolation among sibling species, and reproduction regulation to coincide with the availability of food and oviposition sites are all potentially impacted by host plant influences on insect sex pheromone communication [2]. In recent years, researchers have looked into how different phytophagous insects behave differently in reaction to plant volatiles depending on their sex, maturity, and mating status [5]. Mature female Bactrocera tyroni (Froggatt) fruit flies (Diptera: Tephritidae) were more drawn to the volatiles in their host fruit than were unmated females [6].…”

Impact of Plant on Insect Behavior and Sex Pheromone Emission

Insects intricately interact with host plants, significantly impacting their behavior and chemical communication, especially in phytophagous species. Insect physiology and behavior, particularly sex pheromone communication, are influenced by host plants, which improves mating and reproduction. While some insects release sex pheromones in response to cues from plants, others use the molecules of their host plants to synthesize sex pheromone precursors. Host plants chemicals synergize with sex pheromones, aiding in insect communication and reproductive success. These interactions shape various aspects of insect behavior, from aggregation formation to mate and host finding strategies, and even reproductive isolation among related species. Understanding these relationships is essential for comprehending ecological dynamics and devising sustainable pest management strategies.

Olfactometer-measured responses of Listronotus bonariensis (Kuschel) (Coleoptera: Curculionidae) to feeding-induced grass volatiles and conspecific frass as influenced by the weevil’s seasonality

This contribution aimed to uncover the unique host plant-finding and spatial ecology of reproductive and diapausing Argentine stem weevil, Listronotus bonariensis, and its adaptive implications in Aotearoa-New Zealand pasture. Still-air two-armed olfactometers revealed the reproductive and diapausing L. bonariensis preferences for plant and weevil-derived volatiles. Winter-collected diapausing weevils were strongly attracted to host plant feeding damage by conspecifics and their frass. Such attraction disappeared when 20 stem weevils were added to the damaged ryegrass. This suggests that L. bonariensis on a damaged host plant above a certain density causes repellency probably avoiding over-exploitation of the host plant. Neither the weevils’ sex nor related physiological condition were found to impart any significant effects. Volatile organic compound (VOC) analysis showed that phenylacetaldehyde was the only de novo synthesised herbivore-induced volatile compound found resulting from diapausing L. bonariensis feeding damage. This study therefore found that the seasonal behaviour of L. bonariensis was very closely related to that of the rice water weevil Lissorhoptrus oryzophilus and its very similar responses to phenylacetaldehyde. In both cases the compound attracts spring populations (emerging from diapause) to their host plants and conspecifics. Thereafter, as with L. oryzophilus, L. bonariensis similarly on becoming reproductive, its sensitivity to phenylacetaldehyde ceases. Such close connection between L. bonariensis and L. oryzophilus seasonal responses to phenylacetaldehyde therefore greatly reenforces the concept of evolved L. bonariensis behaviour in its native range as being relict behaviour in New Zealand’s grassland ecosystem.
