Summary: Plant-derived volatile organic compounds play key roles in interactions with insect herbivores, acting as toxic or deterrent agents, signal molecules, and priming signals for plant tissues. The functions of VOC blends are strongly influenced by environmental conditions and specific plant-insect interactions. The complexity of plant-insect chemical communication via VOCs is enriched by the sophisticated molecular perception mechanisms of insects, which influence insect behavior in ways that are not fully understood.

Summary: Threats to food security require sustainable agriculture practices for insect pest management. Conservation biological control (CBC) relies on pest control services provided by local populations of arthropod natural enemies. This review discusses past strategies using chemical ecology in CBC and proposes future directions, including leveraging induced plant defenses and genetically engineered crops.

Summary: This study found that high levels of flavonoids in tomatoes enhance the plant's direct and indirect defenses against herbivores, increase resistance to pests, and attract predatory bugs. The high levels of flavonoids suppress the growth of herbivores and promote plant growth. Therefore, the use of transgenic plants can utilize the beneficial role of flavonoids in integrated pest management while maintaining or improving resistance against other pests and pathogens.

Summary: Water availability has a significant impact on plant-herbivore interactions. This review summarizes recent research on the effects of water availability on plant antiherbivore defense and the physiological processes involved. Water deficit tends to enhance certain defense traits but negatively affects others, and the impact of water availability on species interactions and plant evolution is discussed. However, there is a lack of study on the interactive impact of additional abiotic stressors on water-plant-herbivore interactions.

Summary: Parasitoids induce physiological changes in their herbivorous hosts that affect plant responses to herbivory. However, the interactions among parasitoid larvae have received little attention. This study reveals that there are indirect plant-mediated interactions between parasitoid species, but only when feeding sequentially, not simultaneously.

Summary: Plant-herbivore interactions play a crucial role in the biodiversity of ecosystems. This study investigates the defensive strategies employed by swamp white oak against insects and large mammals. The results show that plant defense strategies vary spatially on individual trees, and the presence of different herbivores can affect the composition of plant defenses.

Summary: Pea plants grown with rhizobia exhibit reduced herbivory by Sitona lineatus due to increased expression of hormone-related and physical defenses. However, herbivory also disrupts the symbiosis between pea plants and rhizobia.

Summary: This study revealed significant differences in defense syndromes between native and introduced populations of an invasive plant, with varying associations with climate and herbivory. Native plant populations exhibited three main defense syndromes correlated with latitude, while introduced populations only had two syndromes, one of which was unique to the introduced range. The results suggest that invasive plants may exhibit different latitudinal patterns of defense syndromes under new environmental conditions, emphasizing the importance of considering geographical dependence in studies on the evolution of defense in invasive plants.

Summary: The indirect interactions between a focal and alternative resource mediated by a generalist consumer can be influenced by associational effects, resulting in various dynamics such as apparent competition and apparent mutualism. The inclusion of density-dependence expands the range where alternative resources positively influence the focal resource.

Summary: Many animals actively adjust their diet to maintain nutrient balance and improve performance. This study found that predatory mites have higher oviposition rates when feeding on a mixture of eggs from different prey species. They actively select prey to obtain a mixed diet and commute between different plant parts to find these prey.

Summary: The intrinsic rate of natural increase (r(m)) is a key parameter in entomology and acarology, especially in studying the potential biological control agents of fast-growing pests. This study proposes a new method for estimating r(m) from partial life tables, allowing researchers to decide when to terminate life-table experiments based on the chosen precision. This method saves experimental time without compromising the reliability of the estimated growth parameter.

Summary: Damage by herbivores can modify plant structure and physiology, affecting the behavior and performance of future herbivores. This study found that necrosis caused by two mite species on coconuts facilitated access by caterpillars to the meristematic zone. The caterpillars primarily co-occurred with one mite species and preferred nuts with easy access to the meristematic region, regardless of mite presence. The presence of one mite species improved caterpillars' performance, but did not affect female moth oviposition preference. these findings suggest that mite damage plays a role in the infestation of coconuts by the moth.

Summary: Herbivores choose host plants based on plant quality, the presence of predators and competitors. The spider mite Tetranychus evansi suppresses plant defences and benefits later-arriving herbivores. The web produced by T. evansi prevents other herbivores from settling on the plant and benefiting from the suppressed defences. The whitefly Bemisia tabaci is negatively affected by the web of spider mites and prefers plants without the web.

Summary: Dispersal plays a crucial role in the dynamics and persistence of predator-prey metapopulations, with different dispersal strategies leading to variations in prey exploitation levels and influencing interaction times and numbers of dispersing predators. Experimental studies in the predatory mite Phytoseiulus persimilis suggest that timing of dispersal is a heritable trait that can result in quantitative differences in local predator-prey dynamics, providing opportunities to investigate the evolution of alternative prey exploitation strategies and select for predator strains with better biological control outcomes.

Summary: Many grass species use silicified trichomes, prickles, and spines to protect their basal meristems. Rice and broomsedge leaves with these features experience more chewing damage to the tips than the bases, suggesting that small herbivores are directed away from vulnerable meristems. Removing the silicified structures increases the frequency of damage to leaf sections without trichomes and prickles.

Summary: Herbivory-induced plant volatiles (HIPVs) play a role in communication among plants, herbivorous insects, and carnivorous arthropods. This review focuses on the specificity of plant-carnivore communication mediated by specific blends of HIPVs, as well as the communication between plants and herbivores, and plants and other plants mediated by specific HIPVs. Factors influencing the net benefits of HIPV production are also examined. These specific means of communication contribute to the complexity of the interaction-information network, which should be further explored to understand the mechanism underlying species coexistence in ecosystems.

Summary: The effects of plant quality on the performance of a phytophagous mite were evaluated on intact plants and leaf discs. The mites produced fewer eggs on detached leaf discs than on intact plants. The oviposition rate of the mite was lower on plants infested with the inducer strain than on plants infested with the suppressor strain or uninfested plants.

Summary: This study identified 2,3,5,6-tetramethylpyrazine (TMP) as a new attractant for capturing booklice in combination with UV light. Cocoa powder was found to weakly attract booklice in total darkness and enhance the attraction to light. The combination of TMP and UV light almost doubled the attraction of booklice compared to light only. This research provides a practical new way to monitor and capture booklice.
