Summary: This study clarified the differences in the ability of Solanaceae crops and the pepino melon to attract gravid Zeugodacus tau females. The volatile odors of Solanum muricatum were identified and the compounds inducing behavioral responses in gravid Z. tau females were determined. The results showed that the odor of S. muricatum was attractive for Z. tau females, and the nine compounds from the volatiles of S. muricatum induced behavioral responses in gravid Z. tau females. These results are beneficial for preventing Z. tau females from harming S. muricatum, developing attractants and repellents, and establishing ecological control for Z. tau females.

Summary: This study found that generalist insect herbivores exhibit differences in host plant selection, with larvae showing higher survival rates on plants where more eggs were laid under experimental conditions. The attractiveness of different types of host plants to moths and caterpillars did not fully align, and oviposition was better correlated with larval survival rates than with larval attraction to host plants.

Summary: Retrospective host range testing is crucial for understanding the physiological host range of biological control agents and non-target risks. This study focused on determining the host ranges of Trissolcus basalis and Trissolcus oenone in New Zealand. The results showed that T. basalis attacks and develops in all tested pentatomid species, while T. oenone attacks and develops in seven out of eight species. The importance of physiological host range testing for assessing non-target effects is discussed in the context of introducing Trissolcus japonicus for brown marmorated stink bug control.

Summary: The study found that adult fall armyworms prefer to lay eggs on both transgenic and conventional maize, but oviposition significantly increased on transgenic maize after being damaged by fall armyworm larvae. Field trials showed that fall armyworms prefer to oviposit on maize with less damage at the early stage, and adults mainly laid eggs on Bt maize, resulting in lower larval density and leaf damage rating compared to conventional maize.

Summary: Plant-insect interactions are complex, involving multiple trophic levels and species. Herbivore attack on a host plant changes the plant's odor emission, and well-adapted herbivores can judge these changes to determine host suitability. However, the molecular and olfactory mechanisms underlying the effects of previous infestations on oviposition preferences remain unknown.

Summary: In a heterogeneous and changing environment, oviposition site selection plays a crucial role in the survival and fitness of offspring, while larval competition also influences their prospects. However, the involvement of pheromones in regulating these processes is still not well understood. This study demonstrates that mated females of Drosophila melanogaster prefer to lay eggs on substrates containing extracts of conspecific larvae. Further experiments identify (Z)-9-octadecenoic acid ethyl ester (OE) as the compound responsible for this preference, which activates female tarsal Gr32a+ neurons. This cross-generational communication strategy is essential for oviposition site selection and regulation of larval density.

Summary: Ticks are important vectors of pathogens, and understanding their chemoreception mechanisms can help in tick management. Two NPC2 genes were cloned and functionally characterized in Rhipicephalus linnaei, a species of brown dog tick. These genes were expressed in all developmental stages, with the highest expression in adult males. Ligand binding analysis showed that R.linNPC2b had a wide spectrum of ligand binding, while R.linNPC2a had a more narrow range. Molecular docking suggested that specific amino acid residues in these proteins may play a key role in ligand recognition. These findings contribute to our understanding of the olfactory mechanisms in R. linnaei and provide new directions for tick management.

Summary: Many animals engage in cannibalism for dietary supplementation, and this is also prevalent among dense populations of migratory locusts. This study shows that locusts produce an anticannibalistic pheromone called phenylacetonitrile under crowded conditions. The degree of cannibalism and phenylacetonitrile production are dependent on population density. By identifying the olfactory receptor that detects phenylacetonitrile and inactivating the gene responsible for its production, researchers demonstrate the loss of protection against intraspecific predation in locusts lacking this compound. This research sheds light on the importance of an anticannibalistic feature in locust population ecology and its potential for locust management.

Summary: Olfaction is a crucial sensory modality in insects, but the regulation of odorant receptor function and intracellular signaling pathways in the sensory periphery are not fully understood. This study investigates the presence and role of nitric oxide (NO) signaling in the antennal tissue of Drosophila. The researchers find that while the NO signaling machinery is present, inhibiting or activating the NO-cGMP pathway does not affect olfactory responses. Additionally, cyclic nucleotides cAMP and cGMP have no effect on olfactory responses, suggesting that NO may not be a regulator of olfactory transduction in insects.

Summary: Little is known about how animals overcome temporal constraints on movement during dispersal. This study used GPS tracking of vulturine guineafowl and found that dispersers showed the greatest increase in movement at the same times of day when they moved the most prior to dispersal. These findings suggest that individuals face the same ecological constraints during dispersal as they do in daily life and achieve large displacements by maximizing movement when conditions are most favorable.
