Les principaux ravageurs des agrumes [PDF]

, 2023
A Mayotte, les agrumes sont attaqués par différents animaux, principalement des insectes. Ils peuvent être plus ou moins dommageables pour l'arbre et la production, en fonction du taux d'infestation et du type de dégâts. Cochenilles, aleurodes, psylles et pucerons vivent en colonies plus ou moins nombreuses, et parfois mélangées.

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Cultivating biophilia: Domestic gardens foster positive emotions towards wildlife, with gardening influence shaped by species' ecological functions

People and Nature, Volume 8, Issue 5, Page 1218-1232, May 2026.
Abstract Understanding how different types of nature interactions influence emotional responses to animal species is especially important in the context of the biodiversity crisis, as these emotions can shape conservation‐related attitudes and behaviours. Gardening is recognised as one such interaction, although its influence likely depends on the type

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

EPPO Bulletin, Volume 56, Issue 1, Page 130-137, April 2026.
Abstract The presence of Thrips parvispinus (Karny, 1922) is reported for the first time in Italy. Prior to this finding, within Europe the pest was only known to be established in Spain. The discovery happened in a greenhouse cultivating gerberas in south‐eastern Sicily, a region recognized as Italy's primary and one of Europe's most important ...

First occurrence of Etiella zinckenella (Treitschke) (Lepidoptera: Pyralidae) in soybean crops in Greece and its potential parasitoid Dolichogenidea appellator (Telenga) (Hymenoptera: Braconidae)

EPPO Bulletin, Volume 55, Issue 3, Page 494-502, December 2025.
Abstract This work documents the first occurrence of Etiella zinckenella (Lepidoptera: Pyralidae) infestations in soybean crops in Greece, and in particular within the Regional Unit of Drama, north‐eastern Greece. Larvae of this pest inflict direct damage by feeding on seeds and cause indirect damage by reducing crop marketability, resulting in ...

Climate‐specific dynamics of fall armyworm on maize: Implications for pest monitoring and management

Agricultural and Forest Entomology, Volume 27, Issue 4, Page 600-612, November 2025.
FAW moth captures were higher in the Sudanese zone than the Guinean zone, peaking during the major rainy season, while the Guinean zone had more captures in the dry season. In the Guinean zone, plant damage correlated with adult moth captures and larval densities, whereas no such correlation was found in the Sudanese zone or at different maize growth ...
