First report of the parasitoid wasp Aneuclis melanaria (Hym.: Ichneumonidae: Tersilochinae) from Iran [PDF]
In 2013, we launched a project to collect and identify the insects, which were associated with the pistachio gall aphid species Forda hirsuta Mordv. and Slavum mordvilovi Kreutz in Tang-Shekan region of the city of Arsanjan in the province of Fars.

ABSTRACT Plant galls are abnormal growing tissues induced by various parasitic organisms, exhibiting diverse and complex morphologies. Typically, these galls differ significantly in appearance from their host plants. Here, we report that larvae of a parasitic fly generate unique, rosette galls on Aster scaber, a perennial herb. These galls develop from

Gall-Colonizing Ants and Their Role as Plant Defenders: From ‘Bad Job’ to ‘Useful Service’
Galls are neoformed structures on host plant tissues caused by the attack of insects or other organisms. They support different communities of specialized parasitic insects (the gall inducers), and can also provide refuge to other insects, such as moths,

Abstract Quantifying the impact of lower trophic level species abundance on higher trophic level predators (and vice versa) is critical for understanding marine ecosystem dynamics and for implementing ecosystem‐based management. Trophic ecosystem models generally predict a tight coupling between prey and fish predators, such that higher abundance of ...

THE PRESENT PEST STATUS OF EUCALYPTUS SAP-SUCKERS AND GALL WASPS IN CAMPANIA (ITALY) [PDF]
Sap-suckers and gall wasps may be a severe phytosanitary problem for several Eucalyptus species, particularly for the red gum E. camaldulensis, the most widely cultivated Australian native tree species worldwide.

Estimating (Non)Linear Selection on Reaction Norms: A General Framework for Labile Traits
It remains difficult to empirically estimate nonlinear selection on individual reaction norms, inhibiting robust tests of adaptive theory and accurate predictions of phenotypic evolution for labile traits. To address this challenge, we propose generalized multilevel models for estimating stabilizing, disruptive, and correlational selection on the ...

Practices to manage chestnut orchards infested by the Chinese gall wasp
The rapid spread of the Chinese gall wasp (Dryocosmus kuriphilus Yasumatsu) in Italian chestnut growing areas is causing new criticisms. In this context, in addition to a clear plant suffering due to the wasp infestation, the dangerous recurrence of ...
