In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Note technique : Entre expérimentations scientifiques et veille écologique: comment évaluer des mesures d’atténuations proposées par une étude d’impacts? Le cas de canalisations enterrées dans la plaine de Crau [PDF]
L’évaluation de la pertinence des mesures d’atténuations proposées par une étude d’impacts lors d’un projet d’aménagement s’effectue par la mise en place de veilles écologiques. Néanmoins, ce type de suivis est rare puisqu’aucune législation ne l’impose.

Flowers and Insects. XXIII [PDF]
The flower groups are divided into (i) a social set, whose flowers are in heads, spikes, or close umbels, so that insects pass from one to another without taking wing or climbing; and (2) a non-social set. The latter contains 54.4 per cent of the flowers, and is divided into Ma, I2I long-tongued bee flowers, and II adapted to birds, hawk-moths, and ...

Our results highlight that prescribed burning in sub‐Mediterranean pine forests does not affect their resistance to PPM in the short term, either positively or negatively, indicating that it can be implemented to reduce wildfire hazard without influencing forest susceptibility to future PPM outbreaks.

More diverse temperate forests are more resistant against non‐native insect herbivores
Promoting mixed forests could be an effective strategy to attenuate the impact of invasion by non‐native forest pests. Abstract In general, trees suffer less damage by insect herbivores when growing in forest mixtures than in tree monocultures. Yet, most current knowledge is based on responses of native herbivores to tree diversity.

AbstractPhylogenomics, the integration of phylogenetics with genome data, has emerged as a powerful approach to study the evolution and systematics of species. Recently, several studies employing phylogenomic tools have provided better insights into insect evolution.
