Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

open access: yesInsect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Breadwinner backlash: The gendered effects of industrial decline

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Low‐skilled men have long been vulnerable to globalization, decarbonization, and other forms of economic disruption. When shocks are realized, women often increase their paid labor to compensate for men's loss of income. We study how layoffs of low‐skilled men and concurrent shifts in workforce composition toward women affect voting.
