Y a-t-il élimination d'Eupelmus orientalis Crawford par Eupelmus vuilleti Crawford (Hymenoptera : Eupelmidae) des systèmes de stockage du niébé (Vigna unguiculata Walp) ? [PDF]
Annales de la Soci\'et\'e Entomologique de France 43, 2
(01/06/2007) 139-144, 2007 Ni\'eb\'e is a food leguminous plant cultivated in tropical Africa for its seeds rich in proteins. The main problem setted by its production is the conservation of harvests. In the fields as in the stocks, the seeds are destroyed by pests (bruchids). These bruchids are always associated with several entomophagous species of hymenoptera.

Further contributions to the tritrophic plant-aphid-parasitoid associations in Malta with special reference to Aphis nerii (Hemiptera, Aphidoidea) as a prevalent refugium of Aphidiinae (Hymenoptera, Braconidae) [PDF]
, 2013 Four species of aphid parasitoids, namely Aphidius colemani, Binodoxys angelicae, Lysiphlebus fabarum and Lysiphlebus testaceipes were reared from Aphis nerii on Nerium oleander and/or Stephanotis floribunda in Malta.

Plant Species Biology, EarlyView.This article details the invasion of cycad aulacaspis scale into the islands of Okinawa‐Jima and Amami‐Oshima. Several recommendations are proposed in this article by members of the IUCN cycad specialist group and experts in the biological control of this scale insect.

Plant 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

Insect Science, EarlyView.Abstract Knowing how environmental conditions affect performance traits in pest insects is important to improve pest management strategies. It can be informative for monitoring, but also for control programs where insects are mass‐reared, and field‐released.

Ecology and EvolutionHow does diversity in nature come about? One factor contributing to this diversity are species interactions; diversity on one trophic level can shape diversity on lower or higher trophic levels.

Characterizing spatiotemporal patterns in three-state lattice models [PDF]
J. Stat. Mech. (2009) P02042, 2009 A two-species spatially extended system of hosts and parasitoids is studied. There are two distinct kinds of coexistence; one with populations distributed homogeneously in space and another one with spatiotemporal patterns. In the latter case, there are noise-sustained oscillations in the population densities, whereas in the former one the densities ...

Insect Science, EarlyView.Abstract Circadian rhythms are self‐sustained endogenous oscillations that are found in all living organisms. In insects, circadian rhythms control a wide variety of behavioral and physiological processes, including feeding, locomotion, mating, and metabolism.

An effective molecular approach for assessing cereal aphid-parasitoid-endosymbiont networks
Scientific Reports, 2017 Molecular approaches are increasingly being used to analyse host-parasitoid food webs as they overcome several hurdles inherent to conventional approaches.

Towards improved pest management of the soybean aphid [PDF]
arXivThe soybean aphid (\emph{Aphis glycines}) is an invasive insect pest that continues to cause large-scale damage to soybean crops in the North Central United States. The current manuscript proposes several mathematical models for the top-down bio-control of the aphid, as well as control via pesticides and neonicotinoids.
