Summary: The study reveals that neonicotinoid insecticides have a long-term impact on the gut microbial community of honeybees, leading to dysbiosis and affecting various microbial genera and species. Microbial diversity is significantly reduced, potentially compromising the ecosystemic functionality of honeybees.

Summary: A study was conducted to evaluate the attractiveness of nineteen host plant volatiles to adult codling moths in apple experiments. The results showed that certain compounds significantly increased moth catches, while others decreased the capture effectiveness. Further research should explore new blends with different component ratios and conduct field trials across various geographical regions.

Summary: Smart traps baited with a nonselective lure successfully monitored codling moth in apple and pear orchards, but automatic counts were inflated in some orchards due to mischaracterizations of primarily similar-sized nontarget moths. Improved image-identification algorithms are needed for smart traps baited with less-selective lures and with lure sets targeting multiple species.

Summary: Using traps baited with kairomone-based lures for female removal was shown to be effective in managing codling moth in organic pear production in Italy and the USA. Fruit injury from codling moth was significantly reduced, and mean fruit protection at harvest was 65% in the USA and 27% in Italy. Further studies should investigate the cost-benefit of matching the intensity of female removal to variable pest pressures.

Summary: This study characterized the herbivore-induced plant volatiles released from infested olive leaves for the first time. The gall midge D. oleae, a specific pest of O. europaea, was found to cause specific plant volatile compounds to be emitted from infested plants. The study also showed increased emission of certain volatile compounds in infested trees, with potential implications for attracting natural enemies of D. oleae.

Summary: Field studies were conducted to test the effectiveness of lure-baited traps in capturing female codling moths. The study found that a specific lure caught the highest number of females, and a bucket trap with a green top and clear bottom was the most effective. Trap density did not significantly affect the capture rate. Additionally, treating females with MD-FR resulted in a significant reduction in fruit damage and mating proportion.

Summary: Combining H. uvarum with spinosad as an attract-and-kill formulation against D. suzukii helps reduce pesticide residues on fruits by targeting treatment to the canopy and decreasing the amount of insecticide per hectare without compromising control efficacy.

Summary: The yeast Hanseniaspora uvarum can manipulate the behavior of Drosophila suzukii by attracting them to insecticide formulations. The yeast attraction competes with grape berries and enhances insecticide effectiveness, suggesting that spray applications targeting the canopy only could reduce residues on fruit without compromising management efficacy.

Summary: We evaluated the effectiveness of palm wine and three other food-based mixtures as baits for trapping C. ditissima and the impact on non-target insects. The results showed that traps baited with palm wine captured more C. ditissima and had a lower proportion of non-target insects compared to traps baited with other lures. This study suggests that cheap palm wine can be used to monitor the presence of C. ditissima in citrus orchards.

Summary: Several sawfly species possess oesophageal diverticula for sequestering plant compounds as defense against predators. In this study, the oesophageal diverticula extract of Susana cupressi, along with other parts of the larvae and hostplant, were analyzed. The results revealed the presence of 48 terpenes, including alpha-cedrene, alpha-fenchene, and germacrene D. The chemical profiles of these compounds showed significant correlations between certain parts of the larvae. The findings suggest that larvae of S. cupressi defend against predators by sequestering and regurgitating hostplant terpenes, including germacrene D.

Summary: The life cycle of the invasive alien insect pest, fall armyworm (FAW), was studied using a colony established from field-collected larvae. Eggs, neonate larvae, and newly emerged adult moths were used to investigate the basic biology of the FAW. The study provides baseline information about the biology of the FAW and aids in future research and management decision-making.

Summary: This study observed the colonization dynamics and density of the European spruce bark beetle in Norway spruce stacks, and tested the behavioral effects of spruce and pine essential oils on the beetles. The results showed that stacks with Scots pine delayed the primary colonization and reduced the secondary colonization, indicating the colonization disruption through nonhost volatiles. Volatile analysis also revealed a significant change in bark emission profiles, with the release of verbenone marking the antiaggregation phase. Behavioral experiments confirmed the attractiveness of spruce essential oil and the strong repellency of pine essential oil.

Summary: Population dynamics of fruit fly species were studied in the southeastern mango enclave of Ghana. A year-long trapping of fruit flies was conducted in three mango orchards, capturing a total of 10 fruit fly species. The population of B. dorsalis and Z. cucurbitae fluctuated from April to July, with B. dorsalis peaking in April, May, and June.
