In this study, we compared the effect of insect feeding vibrations on flavonoid defenses with two other mechanical stimuli, a silent sham treatment and an active touch treatment.

Managing emerging invasive pests can be challenging as repeated insecticide inputs can lead to resistance and impact non-target organisms. Alternative strategies, such as biological control, reduce risks but require extensive investigation before implementation. A recent community science study suggests that arthropods are major predators of L. delicatula. However, this pest can sequester toxins from its preferred host, tree of heaven (Ailanthus altissima), which may defend it from predation. Thus, we tested a variety of predatory arthropods against all life stages of L. delicatula to determine if they would avoid prey fed on A. altissima compared to other host plants. Predatory arthropods did not show a preference when given a choice between L. delicatula reared with access to A. altissima compared to those reared on alternative hosts. We then tested 10 commercially available or easily field-collected generalist predators to determine if these potential biological control agents could reduce L. delicatula populations. Spined soldier bugs (Podisus maculiventris (Say, Hemiptera: Pentatomidae)), Carolina mantids (Stagmomantis carolina (Johansson, Mantodea: Mantidae)), and Chinese mantids (Tenodera sinensis (Saussure, Mantodea: Mantidae)) were the most effective at reducing prey populations, indicating they have promise as effective natural control agents.

We used observational and experimental approaches commonly used and validated for assessing nocturnal pollination, including variation in stigma receptivity and pollen viability at day and night, nectar standing crop dynamics, temporal effects of pollen germination, pollinator exclusion experiments and the presence of pollen on the bodies of potential nocturnal pollinators (moths). Stigma receptivity and pollen viability were similar between our day and night sample points. We found no negative effects of time of pollination on pollen germination. Nectar availability was strongly associated with time of day, and although nectar was available both day and night, nectar volume was highest at night. Fruit set was highest in flowers with unrestricted access to pollinators, but we are unable to determine the relative importance of nocturnal versus diurnal pollination as these treatments gave the same result as our control. Moths caught in blueberry orchards carried pollen from 25 plant species, with blueberry pollen being the fifth most abundant.

The most frequent pollinators were the solitary bees Macrotera sinaloana, Diadasia rinconis, and Lithurgopsis apicalis (Hymenoptera) that collect rewards and perch on the stigma of flowers. Pollinators responded differently to florivory; Ashmeadiella opuntiae avoided flowers with perianth damage, possibly associating it with a lack of rewards, while D. rinconis prefered such flowers, the removal of this structure facilitated access to floral rewards. Flowers in the stigma-perianth treatment produced seedless fruit. Intact flowers had higher seed production than those with perianth damage or emasculation due to low pollinator visitation and pollen deposition.

The seasonal and landscape-level alterations have significant impacts on leafcutter bees, influencing species richness, abundance, community composition and leaf foraging behaviour. This study underscores the critical role of different seasons and landscape characteristics in shaping the leaf-foraging behaviour of leafcutter bees. We noted that semi-urban areas (151 different plant species recorded with cut leaves), with their greater landscape heterogeneity and high-quality habitats, supported higher species richness and abundance of leafcutter bees. In contrast, fully urban (49 different plant species recorded with cut leaves) and intensively agricultural landscapes (85 different plant species recorded with cut leaves) posed challenges to the survival of these bees due to habitat loss and fragmentation. We also found that during early autumn, leafcutter bees emerged and constructed ephemeral nests, intensifying leaf-cutting behaviour, whereas the summer and monsoon seasons exhibited a heightened activity, with bees building seasonal nests and gathering leaf and other essential resources extensively. In winter, leafcutting ceased as these bees entered into dormant conditions, seeking shelter in their nests for insulation and protection.
