Shifts in leaf color during ontogeny do not affect herbivory in the tropical tree Lecythis pisonis (Lecythidaceae)

open access: yesPlant Species Biology, EarlyView.
Leaf color has been rarely evaluated as an important trait influencing herbivory levels in tropical plant species. Cannonball trees (Lecythis pisonis) present pink young leaves that are smaller, softer and with less chlorophyll that progressively turn into green as the season progresses. When all three leaf colors are present in the plants, there is no

Short term response of ants to the removal of ground cover in organic olive orchards

open access: yesEuropean Journal of Entomology, 2011
Ants are the most abundant group of soil arthropods in olive groves where they are involved in various trophic relationships of great importance for crops. The system of soil management is one agricultural practice that has a great effect on ants, so the

The transformer gene controls sexual development in Drosophila suzukii

open access: yesInsect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

The urban island: climatic suitability of Linepithema humile (Hymenoptera: Formicidae) and the role of cities in the invasion of the Western Palearctic

open access: yesIntegrative Zoology, EarlyView.
Urban environments provide favorable conditions for the introduction and spread of nonnative and invasive species like the Argentine ant, which exploit ecological and climatic homogenization in cities to overcome natural barriers. Monitoring the expansion of such species can be achieved through potential distribution models, which in this study ...
