“…This study showed that the sex pheromones can play modulatory roles in gustatory perception in non-social insects, such as moths, and may affect their behavioral plasticity. Follow up studies by Murmu et al [ 126 ] showed that pheromones facilitated both appetitive and aversive olfactory learning in A. ipsilon moths. The exposure to the A. ipsilon conspecific sex-pheromone before conditioning enhanced appetitive but not aversive learning, while exposure to a heterospecific sex-pheromone component facilitated aversive but not appetitive learning.…”

Since the first identification of the silkworm moth sex pheromone in 1959, significant research has been reported on identifying and unravelling the sex pheromone mechanisms of hundreds of insect species. In the past two decades, the number of research studies on new insect pheromones, pheromone biosynthesis, mode of action, peripheral olfactory and neural mechanisms, and their practical applications in Integrated Pest Management has increased dramatically. An interdisciplinary approach that uses the advances and new techniques in analytical chemistry, chemical ecology, neurophysiology, genetics, and evolutionary and molecular biology has helped us to better understand the pheromone perception mechanisms and its practical application in agricultural pest management. In this review, we present the most recent developments in pheromone research and its application in the past two decades.

“…Pheromones do more than conveying specific messages to members of the same species. In insects, for instance, they can modulate in the long term responsiveness to relevant stimuli (appetitive, aversive) in contexts that differ from the one for which the pheromone is used as a messenger (Baracchi et al 2017;Rossi et al 2018;Hostachy et al 2019;Rossi et al 2019;Baracchi et al 2020;Murmu et al 2020;Oberhauser et al 2020;Rossi et al 2020). Further studies are needed to clarify these novel functions of pheromones as neuromodulators and to understand their implications for the functioning of recognition systems in general.…”

Formic acid modulates latency and accuracy of nestmate recognition in carpenter ants

Decision-making processes face the dilemma of being accurate or faster, a phenomenon that has been described as speed-accuracy trade-off (SAT) in numerous studies on animal behaviour. In social insects, discriminating between colony members and aliens is subjected to this trade-off as rapid and accurate rejection of enemies is of primary importance for the maintenance and ecological success of insect societies. Recognition cues distinguishing aliens from nestmates are embedded in the cuticular hydrocarbon (CHC) layer and vary among colonies. In walking carpenter ants, exposure to formic acid (FA), an alarm pheromone, improves accuracy of nestmate recognition by decreasing both alien acceptance and nestmate rejection. Here we studied the effect of FA exposure on the spontaneous aggressive mandible opening response of harnessed Camponotus aethiops ants presented with either nestmate or alien CHCs. FA modulated both MOR accuracy and the latency to respond to odours of conspecifics. In particular, FA decreased MOR towards nestmates but increased it towards aliens. Furthermore, FA decreased MOR latency towards aliens but not towards nestmates. As response latency can be used as a proxy of response speed, we conclude that contrary to the prediction of the SAT theory, ants did not trade off speed against accuracy in the process of nestmate recognition.

“…Habituation is the simplest type of learning behavior in the animal world and refers to the gradual decay of a behavioral reaction during continuous or repeated simulation [16]. The habitual response of insects does not mean acquisition of new responses but refers to repeated contact with some stimulation that decreases the response to that stimulation, and in some cases, specific responses disappear [17,18]. After repeatedly experiencing the mixture of willow and A. chinensis fecula and wood meal at 4 days old, 6 days old, and 8 days old, instead of increasing, the tropism of these adults to odor decreased significantly compared with that of 4-day-old, 6-day-old, and 8-day-old adults that only experienced no obvious cumulative effect of repeated stimulation on learning.…”

Sclerodermus sichuanensisXiao is an important natural enemy of forest boring pests. We used a two-way selection test to investigate the behavioral mechanisms used by S. sichuanensis when searching for hosts. Y-tube olfactometers and electroantennogram recordings were used to study learning by S. sichuanensis exposed continuously or discontinuously to a mixture of longhorn beetle (Anoplophora chinensis Forster) fecula and wood meal, and to mixtures of A. chinensis fecula and wood meal from different trees, either successively or simultaneously. Following exposure of 4-day-old adult S. sichuanensis to a mixture of A. chinensis fecula and wood meal for 3 d, tropism toward this odor did not improve significantly. After discontinuous exposure to a mixture of A. chinensis fecula and wood meal, adult S. sichuanensis exhibited a habitual response and its tropism to this odor decreased markedly. Five-day-old female S. sichuanensis that previously experienced a mixture of A. chinensis fecula and wood meal from two different host trees (willows, Salix sp., and oriental parasol, Platanus orientalis) or a mixture of A. chinensis fecula and wood meal (willows) during the eclosion period and were then stimulated by the mixture of A. chinensis fecula and wood meal (oriental parasol) at 4 days old exhibited a relatively strong behavioral reaction to mixed stimulation by the two types of substrate information. These observations suggest that the learning behavior of S. sichuanensis is cumulative. The parasitoid can differentiate between two kinds of chemical information experienced simultaneously and recognize the two odors when they are experienced successively. This discovery is important for elucidating the behavioral mechanisms of learning in parasitoids and for the development and application of natural enemy insects for pest control.
