Beauveria Bassiana Triggers Soybean Systemic Resistance and Causes Sublethal Effects in Spodoptera frugiperda

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The interaction of soybean plant and the endophytic microorganism Beauveria bassiana was evaluated by inoculating a single trifoliate leaf. The effects of this inoculation on the herbivory, larval development, and life traits of Spodoptera frugiperda were measured.

How Do Female Pest Tephritids Behave During Male Courtship?

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In this paper, the female role during male courtship was described for the first time in fruit flies. Our findings show that females imitate some male behaviors and suggest that certain behaviors are associated with male mating success. Indeed, the Mediterranean fruit fly displays fewer behavioral units (i.e., shorter courtship sequences) than ...

An Easy Method to Sample Headspace Pheromones in the Field

open access: yesEthology, EarlyView.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.
