Behaviours of insects can be manipulated by transmitting vibrational signals to host plants in order to develop pest management techniques. Bactericera cockerelli is an important pest and uses vibrations for mate-finding. In order to design a future control strategy for B. cockerelli, three different bioassays were performed to assess whether vibrational signals could affect relevant behaviours. Single males or pairs were treated with a female playback in test 1 and 2, respectively. In test 3, mixed sex groups received either different disturbance playbacks. The use of a female playback significantly reduced the mating success of males, since they were attracted towards the source of the stimulus. Moreover, test 2 revealed that B. cockerelli females are competitive, since they used their signals to cover the playback and to duet with males, while in test 3, the disturbance playback, consisting of broadband noises significantly reduced male signalling activity. However, none of the treatments of test 3 negatively affected the mating success of males, which tended to mount the other conspecifics present on the same leaf. The role of vibrations in sexual communication and their potential application as control technique for B. cockerelli are discussed as well.

Herbivore-induced plant volatiles (HIPVs) synergize with the sex pheromones of herbivorous insects to facilitate mate location. However, the synergism of HIPVs and acoustic signals for sexual communication remains unknown. Here, we investigated the synergy between HIPVs and vibrational duets for sexual communication and mating in the pea leafminer ( Liriomyza huidobrensis ). Our results indicated that adult leafminers do not produce species-specific pheromone, and female-puncture-induced plant volatiles facilitate the attraction of both sexes to host plant leaves and sexual encounters. Insect-derived cues do not participate in mate locations. Both sexes do not produce qualitatively different cuticular hydrocarbons (CHCs), and CHCs from females cannot elicit the antennal and behavioural responses of males. By contrast, induced green leaf volatiles, terpenoids and oximes elicit dramatic antennal responses in both sexes. Electrophysiological and behavioural tests consistently showed that the volatiles (Z)-3-hexenol and (Z)-3-hexenyl-acetate elicited the most intense gas chromatographic-electroantennographic responses, and attracted males and females. Remarkably, these volatiles significantly promoted the occurrence of vibrational duets between the sexes, thereby increasing the mating success of leafminers. Therefore, the synergism of HIPVs and vibrational signals largely promoted the mating success of leafminers, suggesting an alternative control strategy through precision trapping for non-pheromone-producing insects.

Sexual communication is a pivotal part of interpersonal relationships; recent research reveals associations between sexual communication and various relational outcomes. Within the broad domain of sexual communication, current scholarship specifically addresses the role of postsex communication in relationships and its links to physiological and genetic markers. Given these advancements, the present chapter offers an overview of research linking physiology, hormones, and genes to communication after sexual activity. The chapter first presents reviews of two key hormones in sexual communication research: testosterone (T) and oxytocin (O). The oxytocin receptor gene and its link to social behavior broadly, and sexual behavior specifically, is also explored. The chapter then offers a review of several theories relevant to understanding the hormonal underpinnings of sexual communication, as well as future directions for research exploring sexual communication and physiology.

In the United Kingdom reforms to professional regulation have been introduced to enhance public protection. This chapter accounts for changes from 2002 to 2016 with the introduction of a meta-regulator to oversee nine statutory professional Councils. It examines the expansion of the role of the meta-regulator and reforms within the professional councils themselves. It draws on data collected to show increases in costs and activity and explains the shift from self-regulation to top-down governance using corporate management techniques of audit and review. It demonstrates that the reforms have been evolutionary and that further reform is ongoing.

The tomato/potato psyllid Bactericera cockerelli (Sulc) (Hemiptera Triozidae) is an introduced pest of solanaceous crops in New Zealand A range of established plants play host to Bactericera cockerelli including three traditional Maori food sources taewa or Maori potatoes (Solanum tuberosum ssp andigena) kumara (Ipomoea batatas) and poroporo (Solanum aviculare) Taewa and kumara are highly susceptible to summer B cockerelli infestation whilst poroporo an evergreen plant remains susceptible yearround and provides overwintering refuge Extensive monitoring of each host plant was carried out to determine the significance of each host in the lifecycle of B cockerelli in New Zealand Poroporo was monitored from late autumn for 6 months to determine if the plant served as a significant overwintering host for the pest after harvesting summer crops Taewa and kumara plants were monitored throughout the summer growing season on a weekly basis increasing to twice a week as populations proliferated Host plants were monitored both in the natural environment and under laboratory conditions Data collected contributed to tracking population development of B cockerelli on each host including the length of each life stage (ie egg nymph adult) Comparisons between the three hosts revealed host preference host suitability and the significance of each host in the lifecycle progression of B cockerelli

Autophagy, also known as type II programmed cell death, is a cellular mechanism of “self-eating”. Autophagy plays an important role against pathogen infection in numerous organisms. Recently, it has been demonstrated that autophagy can be activated and even manipulated by plant viruses to facilitate their transmission within insect vectors. However, little is known about the role of autophagy in the interactions of insect vectors with plant bacterial pathogens. ‘Candidatus Liberibacter solanacearum’ (Lso) is a phloem-limited Gram-negative bacterium that infects crops worldwide. Two Lso haplotypes, LsoA and LsoB, are transmitted by the potato psyllid, Bactericera cockerelli and cause damaging diseases in solanaceous plants (e.g., zebra chip in potatoes). Both LsoA and LsoB are transmitted by the potato psyllid in a persistent circulative manner: they colonize and replicate within psyllid tissues. Following acquisition, the gut is the first organ Lso encounters and could be a barrier for transmission. In this study, we annotated autophagy-related genes (ATGs) from the potato psyllid transcriptome and evaluated their expression in response to Lso infection at the gut interface. In total, 19 ATGs belonging to 17 different families were identified. The comprehensive expression profile analysis revealed that the majority of the ATGs were regulated in the psyllid gut following the exposure or infection to each Lso haplotype, LsoA and LsoB, suggesting a potential role of autophagy in response to Lso at the psyllid gut interface.
