“…Other mechanisms that can affect pheromone production and release are pathogens [19], volatiles from host plants [31], conspecifics [35,36], or prey [37]. Verheggen et al [37] recently found that pheromone production in the Asian lady beetles (Harmonia axyridis) (Figure 1A) is conditioned by the presence of prey, as exposure to volatiles of the prey initiated pheromone production. Also, the female calling behavior of the gregarious beet webworm moth (Loxostege sticticalis) is affected by the vicinity to male conspecifics [38].…”

“…Pheromonal blend has been recently characterized for H. axyridis , with (–)-β-caryophyllene being the most abundant molecule [95]. The pheromone is emitted by virgin and mated females, primarily under the presence of adequate aphid preys [96]. Major sex pheromone compounds are individually perceived by both sexes, while the complete pheromonal blend elicited behavioral attraction on males only [90].…”

In predatory ladybirds (Coleoptera: Coccinellidae), antennae are important for chemosensory reception used during food and mate location, and for finding a suitable oviposition habitat. Based on NextSeq 550 Illumina sequencing, we assembled the antennal transcriptome of mated Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) males and females and described the first chemosensory gene repertoire expressed in this species. We annotated candidate chemosensory sequences encoding 26 odorant receptors (including the coreceptor, Orco), 17 gustatory receptors, 27 ionotropic receptors, 31 odorant-binding proteins, 12 chemosensory proteins and 4 sensory neuron membrane proteins. Maximum-likelihood phylogenetic analyses allowed to assign can-didate H. axyridis chemosensory genes to previously described groups in each of these families. Differential expression analysis between males and females revealed low variability between sexes, possibly reflecting the known absence of relevant sexual dimorphism in the structure of the antennae and in the distribution and abundance of the sensilla. However, we revealed significant differences in expression of three chemosensory genes, namely 2 male-biased odorant-binding proteins and 1 male-biased odorant receptor, suggesting their possible involvement in pheromone detection. Our data pave the way for improving the understanding of the molecular basis of chemosensory reception in Coccinellidae.

“…Whereas the production of sex pheromone occurs in females for increasing their chances of future mating (Verheggen et al, 2020), males access these olfactory stimuli to discriminate female mating status to attain fitness by choosing whether to mate or not (Thomas, 2011;Singh et al, 2020). Cuticular hydrocarbons are also involved in mate recognition and become more effective with time (Brown et al, 2006;Johansson & Jones, 2007;Legrand et al, 2019).…”

For food security and sustainable crop protection, it is a necessity to optimize the massrearing and augmentation of biocontrol agents of numerous aphid pests. Coccinellids, commonly known as ladybird beetles, are potential predators on several sucking pests and promising biocontrol agents. In the present investigation, laboratory experiments were performed to find out whether manipulation of mate choice in aphidophagous ladybird Coccinella transversalis Fabricius (Coleoptera: Coccinellidae) under varying mating status could influence reproductive output in terms of high fecundity. It was found that the mating status under the mate choice highly affects mating duration and fecundity. The mating commenced earlier under the presence of different males than the females in an arena. The mating lasted for a longer duration between virgin females and multi-mated males than vice-versa. The bouts in copula increased with an increase in the mating status in both sexes. Females of multi-mated status were more fecund than the unmated females. Thus, the present study will be useful for the manipulation of quantitative mass-rearing of C. transversalis for the biocontrol of aphids and thereby enhancing crop productivity and sustainable crop protection.
