Summary: The use of essential oils has been found to enhance male mating success in several species of Tephritidae fruit flies, particularly in Anastrepha fraterculus exposed to commercial guava essential oil. Sexual stimulation from guava oil was observed only when males were exposed after attaining sexual maturation and fed on a low-quality diet, while males fed on high-quality diet showed higher calling levels regardless of guava oil exposure. The treatment did not have detrimental consequences on male starvation resistance.

Summary: The study identified a mixture of five hydrocarbons shared between Pterostylis orbiculata orchids and female Mycomya sp. fungus gnats, including an undescribed triene compound that was confirmed to be (6Z,9Z)-1,6,9-tricosatriene. Field bioassays showed that this triene, along with other hydrocarbons, elicited attraction and sexual behavior from male gnats, indicating its importance as a key component in orchid pollinator attraction and female fungus gnat sex pheromones. This suggests that long-chain unsaturated hydrocarbons play a crucial role in sexual deception in Pterostylis orchids and provide a valuable insight into deciphering female fungus gnat sex pheromones.

Summary: Tsetse flies engage in chemical communication through volatile pheromones, specifically methyl palmitoleate, which elicits strong behavioral responses. This compound induces G. morsitans males to mount females of another species, Glossina fuscipes. Infection with African trypanosomes alters the flies' chemical profile and mating behavior, indicating the potential usefulness of identifying volatile attractants in tsetse flies for reducing disease spread.

Summary: The research highlights the identification of volatile lactones from Madagascan Mantellidae and African Hyperoliidae frogs, demonstrating that frogs use chemical communication in addition to acoustic channels. The focus is on synthetic approaches to clarify the constitution and configuration of glandular compounds, as well as the use of GC/MS analysis, GC/IR, microreactions, and synthesis for identification.

Summary: The study found that using ipsenol, an aggregation pheromone of Ips grandicollis, on jack pine logs can attract more Ips grandicollis compared to logs baited with pheromones of mountain pine beetle and host volatiles. The presence of lures for mountain pine beetle inhibits colonization by Ips grandicollis, while longhorn borers are more attracted to logs baited with ipsenol. These results suggest that common bark and woodboring species like Ips grandicollis and longhorn borers may not compete with mountain pine beetles at tree-colonizing stages, posing little resistance to invasion if mountain pine beetle were to invade the Great Lakes Region.

Summary: By analyzing sexual interactions in Pachyloides thorellii, this study identified specific behaviors exhibited by females before and during mating, which are related to their sexual receptivity and cooperation with mating. The study also found that males use multimodal courtship displays that involve tactile and possibly chemical signals exchange between sexes.

Summary: Agricultural crop productivity relies on the use of chemical pesticides to reduce damage caused by pests and pathogens. However, these pesticides have negative ecological, environmental, and economic impacts. Therefore, alternative sustainable methods, such as manipulating semiochemicals, should be considered for crop protection.

Summary: Kairomones are chemical signals that mediate interspecific interactions beneficial to organisms that detect the cues. Natural enemies eavesdrop on kairomones during foraging behavior and are likely to elicit stronger olfactory responses in natural enemies. Kairomone-based lures can be used to reduce insect pest populations and crop damage in an environmentally friendly way, and future studies should focus on the application of kairomone blends to improve biological control strategies.

Summary: Spiders, especially Araneomorphae, have been extensively studied for their courtship behaviors, while the understanding of courtship in Mygalomorphae is limited. This study focuses on the courtship behaviors of a mygalomorph, the Sydney funnel-web spider, and describes new behaviors not previously observed in this group. The mating positions and behaviors of males and females are also detailed. The research provides valuable insights into the evolutionary aspects of sexual selection in Mygalomorphae, which has been understudied and biased towards tarantulas.

Summary: Insect pheromones can be degraded by the air pollutant ozone. Jiang et al. show that ozone-exposed male flies lose their pheromones and become less attractive to females. Additionally, ozone-exposed males exhibited increased male-male courtship behaviour as a result of reduced sex recognition.

Summary: The use of nectar-producing companion plants can help in biological control. This study found that floral volatiles from marigold are attractive to the parasitoid Aphidius platensis, and more attractive than volatiles from sweet pepper plants. However, volatiles emitted by aphid-infested sweet pepper were as attractive as those of uninfested or aphid-infested marigold.

Summary: A novel trisubstituted tetrahydropyran was isolated from the sex-specific volatiles produced by males of the cerambycid beetle Macropophora accentifer. Although this compound was the major component, it was weakly attractive to beetles of both sexes in field trials, suggesting that the presence of the unnatural enantiomer in the racemate might inhibit the attraction. The male-produced volatiles also contained minor and trace components, and further research is needed to identify and synthesize these compounds to determine their role in the active pheromone blend for this species.

Summary: Cyclocephaline beetles are primarily attracted to major floral volatiles. The volatile compounds identified from trumpet flowers, such as eucalyptol, methyl benzoate, and beta-myrcene, were found to attract the beetle Cyclocephala paraguayensis. The blend of Mebe and nerolidol showed a synergistic interaction in attracting the beetles.

Summary: This study examines the effects of nutrient availability and induced resistance on plant-herbivore interactions. It suggests that higher fertilizer rates lead to increased nutrient content in tomato plants, making them more preferred by T. absoluta. However, the application of defensive phytohormone MeJA can counteract this preference. Interestingly, there was no significant interaction between fertilizer and MeJA, indicating that the induced responses against T. absoluta remain similar regardless of fertilizer rates.

Summary: Based on the theory of optimal foraging and preference-performance hypothesis, gravid females of Diabrotica speciosa, a cucurbit beetle, select plant hosts for oviposition that benefit themselves or their offspring. This study investigated the use of volatiles emitted by non-infested maize plants and herbivore-infested plants by conspecific immatures and adults by gravid females in host selection. Results showed that the presence of conspecifics on maize plants triggered volatiles emission, influencing the host selection for oviposition. Gravid females avoided plants infested by larvae and plants infested by larvae and adults. Leaf-infested plants did not affect the host-selection behavior. Weight gain of larvae was higher on non-infested and leaf-infested plants, indicating that female preference is related to offspring performance.

Summary: Abiotic factors have a strong influence on ecological interactions and spatial distribution of organisms. Barometric pressure, an essential factor, has a poorly understood impact on insect behavior, especially in predators. This study investigates how different predatory insects adapt their foraging behavior to variations in barometric pressure, and also examines the response of different life stages to these pressure fluctuations. The results provide insights into the effects of barometric pressure on insect foraging efficiency and predator-prey interactions, highlighting the importance of studying abiotic factors in the context of climate change.
