Host influence on life history traits of Wiedemann in an arid region of Argentina.
Bull Entomol Res
November 2024
Estación Experimental Agropecuaria INTA, San Juan, Argentina.
Article Synopsis
- The fruit fly demonstrates adaptability through trade-offs in its life history traits, allowing it to thrive on different fruit hosts like peach, plum, and fig in arid conditions.
- Research found that the choice of host affects various traits, including pupal abundance, sex ratio, and physical measurements such as weight and wingspan.
- Males reared on figs showed earlier sexual maturity, emphasizing the importance of understanding these interactions for effective management of local orchards and fruit plantations.
Sawfly Sex Pheromones: Analysis of Their Impact on Pine Odor Attractive to Egg Parasitoids.
J Chem Ecol
November 2024
Applied Zoology/Animal Ecology, Institute of Biology, Freie Universität Berlin, Berlin, Germany.
Pinus sylvestris trees are known to efficiently defend themselves against eggs of the herbivorous sawfly Diprion pini. Their direct defense against eggs is primable by prior exposure to the sex pheromones of this species and their indirect defense involves attraction of egg parasitoids by egg-induced pine needle odor. But it is unknown whether exposure of pine to D.

Insect-plant interactions are shaped by the exchange of chemical cues called semiochemicals, which play a vital role in communication between organisms. Plants release a variety of volatile organic compounds in response to environmental cues, such as herbivore attacks. These compounds play a crucial role in mediating the interactions between plants and insects.

Bactrocera tryoni (Froggatt) and Bactrocera neohumeralis (Hardy) are sibling fruit fly species that are sympatric over much of their ranges. Premating isolation of these close relatives is thought to be maintained in part by allochrony-mating activity in B. tryoni peaks at dusk, whereas in B.

Tribolium castaneum and Rhyzopertha dominica are cosmopolitan, destructive postharvest pests. Although research has investigated how high densities of T. castaneum affect attraction to the aggregation pheromone by conspecifics, research into the behavioral response of both species to food cues after high density exposure has been lacking despite its importance to foraging ecology.
