“…On the leg, males possess tibial spurs and claws, which for other species facilitate grasping and control of females, preventing aggregated males from dislodging copulating males and distributing their own CHC profile overall the female's cuticle (80). Thus, mate location and sex discrimination, the first steps of mating, is maybe due to a combination of physical and chemical recognition by the antenna and legs (59).…”

“…All tested beetles were used only once, whereas beetles within the chambers were allowed to acclimatize for 1 h before the tests to avoid them producing unattractive compounds such as alarm pheromones. The assignment of odour sources to each arm was reversed after each trial to avoid potential illumination and directional bias (59). After each test, the olfactometer and chambers were washed with methanol.…”

“…Therefore, circadian behaviour is a crucial component of almost any ecological and evolutionary process (55,57). Thus, basic knowledge such as identifying processes affecting aggregation or mating behaviour addressing their circadian pattern of sexual behaviour is crucial for more efficient pest management (44,(57)(58)(59)(60)(61)(62).…”

Alphitobius diaperinus (Coleoptera: Tenebrionidae), the lesser mealworm, is one of the most significant pests of the poultry industry worldwide. These insects cause structural damage in poultry houses and transmit several diseases, impacting chickens' productivity and rearing costs. Although semiochemicals may offer alternative insect pest management strategies, basic information regarding pheromone identity and their role on the behavioural ecology according to their circadian pattern of sexual behaviour of A. diaperinus is essentially lacking. This study is aimed to analyse the relation of gender identity and sexual experience of adults of A. diaperinus on their mating behaviour and whether this response is related to their CHC profiles secreted. The following steps were taken to achieve the study’s goal. First, the circadian pattern of their sexual activity was observed in newly emerged pairs for at least twenty-one days (virgin adults) and experienced adults collected from the field to identify a difference based on their sexual experience and achieve the optimal mating season to develop the following assays. Subsequently, Y-tube olfactometer bioassays were conducted to evaluate their odour bouquet attraction based on gender and sexual experience. Additionally, mating behaviour bioassays were conducted to evaluate the two factor effects. Finally, cuticular analysis was performed using gas chromatography-mass spectrometry to evaluate possible chemical differences based on the two factors. With statistical and multivariate analysis, we found that behavioural, mating and chemical responses are different based on their sexual experience. The mating sequences were described into precopulatory, copulatory and postcopulatory phases. This finding gives us a deeper understanding of the sexual communication during mating. In summary, our findings provide new insights into the mating system and chemical ecology of A. diaperinus . The results presented here may serve as a base for further studies to develop strategies for managing this pest.

“…The production of aggregation pheromones by the male of a species is not unique (e.g. in the Cerambycidae including Neoclytus acuminatus; Lacey et al, 2004;Hanks & Millar, 2016); the bug Narnia femorata; Addesso et al, 2014; and a weevil Cyrtomon luridus; Kamiya et al, 2014). Although such chemicals usually attract both sexes of a species, Leal et al (1996) demonstrated a pheromone mix (2-(E)-octenyl acetate and octanol) produced by both sexes of rice bug (Leptocorisa chinensis) that attracts males in the field and not females, and does not elicit a sexual response in males.…”

Use of novel attraction compounds increases monitoring success of a rare beetle, Elater ferrugineus

The use of pheromones to determine distributions of rare saproxylic insects is an increasingly popular technique. Pheromones may, however, also be used to elucidate the biology of these cryptic species, a vital requirement if they are to be accurately monitored and conserved. We used non‐invasive aerial trapping to compare the effectiveness of chemicals produced by Elater ferrugineus L (Coleoptera: Elateridae), namely 7‐methyloctyl (Z)‐4‐decenoate (the female‐produced sex pheromone), and male compounds (geranyl and neryl acetone and 6‐methyl‐5‐heptene‐2‐one). The male compounds were identified using headspace analysis by solid phase micro‐extraction gas chromatography‐mass spectrometry. We discovered that males only produce these two compounds after having been attracted to a female, and that this serves to attract further males to a female. Such compounds do not appear to attract females but for a species that has a short activity period and is non‐feeding in the adult stage, may ensure breeding success when populations are low. By marking all beetles caught, we were able to demonstrate that recapture rate using this method is low (approximately 11% of total captures annually). Therefore, the method does not limit dispersal or breeding opportunities, making it a valuable tool for monitoring endangered saproxylic beetle species.

“…Extensive studies have revealed that CHCs act as contact sex pheromones in the mating of some coleopteran species, such as Coccinellidae [3], Curculionidae [4], and Cerambycidae [5,6,7]. In weevils, the behaviors triggered by contact sex pheromones are similar across species, with only a few differences, mainly related to precopulation, copulation, and postcopulation [4,8,9,10,11,12,13,14,15,16,17,18].…”

Cuticular Hydrocarbon Recognition in the Mating Behavior of Two Pissodes Species

Two sibling weevil species, Pissodes strobi Peck and P. nemorensis Germar (Coleoptera: Curculionidae), can form reduced-fitness hybrids in the laboratory, but neither their premating isolation mechanisms nor mating behaviors are well-understood. Cuticular hydrocarbons (CHCs) have been reported as crucial chemical cues in mating recognition in many insects, including weevils, and, thus, may also mediate the mating behavior of P. strobi and P. nemorensis. We conducted a series of behavioral observations, bioassays, and chemical analyses to investigate the role of CHCs in their mating behavior. Copulation behavior of both species followed similar steps: approaching, mounting, tapping, aedeagus extrusion, and copulation. In P. strobi, hexane extraction significantly reduced the number of successful male copulations compared with freeze-killed females. Conversely, significantly fewer P. nemorensis males copulated with dead females compared with live females. No significant differences were detected among hexane-extracted, freeze-killed or recoated female carcasses to P. nemorensis. These findings suggested that female cuticular extracts contain important cues in mate recognition in P. strobi but not in P. nemorensis. We identified 21 CHCs from both species with variation in abundances between sexes and seasons. Discriminant analysis revealed incomplete overlap of CHC compositions in females of the two species in summer, when hybridization potentially occurs.
