ABSTRACT Importation biological control can create new host‐natural enemy responses that are different from those behaviours elicited in native ranges of the agent, and/or the pest. This possibility was investigated with the Argentine stem weevil (Listronotus bonariensis) in the presence of three endoparasitoid species with different levels of affinity

Biological Control of Cotton Aphid by Aphidius colemani(Hymenoptera: Braconidae) in Watermelon Greenhouses [PDF]
Biological control of Aphis gossypii by natural enemies was carried out in watermelon from April to June. Aphidius colemani was released 3 times at rate of to control A. gossypii(April 24, May 8, and May 22 in 2007). In A. colemani-released plots, A.

The influence of genetic variation on pre‐oviposition processes for host‐parasitoid co‐evolution
Co‐evolution between aphid hosts and their parasitoids has been associated with adaptative pressures linked with aphid physiological resistance (related to aphid and their endosymbionts' genetic variation) and parasitoid virulence. The aphid‐parasitoid interaction is composed of multiple previous stages before parasitoid oviposition that has been ...

The aphid Myzus persicae (Sulzer) (Hemiptera: Aphididae) is considered one of the main pests in tobacco crops. By knowing their natural enemies, such as parasitoid wasp, is the first step to develop management strategies for the biological control of the

Another tool in the toolbox: Aphid‐specific Wolbachia protect against fungal pathogens
Wolbachia infected more than 80% of Pentalonia aphids sampled across the Hawaiian Islands and other locations. The aphid‐specific M‐supergroup strains of this symbiont protected against a specialist fungal pathogen, Pandora, but not the generalist pathogen Beauveria or the parasitoid Aphidius colemanii.

Diez especies de áfidos (Hemiptera: Aphididae) se hallaron parasitados por siete especies de parasitoides (Hymenoptera: Braconidae, Aphidiinae) en cultivos hortícolas orgánicos. Myzus persicae (Sulzer) fue el áfido más frecuentemente encontrado sobre una

Body size is a main fitness component of insect parasitoids. We assessed the potential influence of maternal size of the parasitoid wasp Aphidius colemani Viereck (Hymenoptera: Braconidae: Aphidiinae) on its ability to parasitize the different instars of

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Costa Rica
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Costa Rica.

Spinosad was the most toxic active ingredient, in both laboratory bioassays and field trials. Cyantraniliprole resulted as the least toxic and selective one, but showed sublethal effects on longevity at LC30. Abstract Background G1 strain Ganaspis brasiliensis (Ihering) has been recently released in both Europe and America as a biological control agent
