Observations sur la biologie et le comportement cleptoparasite d'Eurytoma waachtli [Chalc.: Eurytomidae], parasite dePissodes validirostris [Col.: Curculionidae] dans les cones de pin sylvestre a Fontainebleau
BioControl - Tập 21 - Trang 289-295 - 1976
Des observations ont été effectuées sur la morphologie des stades préimaginaux et le cycle de développement d'Eurytoma waachtli
Mayr., qui se développe en ectoparasite sur les larves de 4e stade du curculionidePissodes validirostris
Gyll. dans les cônes de pin sylvestre. On a constaté que le chalcidien n'attaque les larves dePissodes que si celles-ci sont préalablement parasitées et paralysées par...... hiện toàn bộ
Host range tests reveal Paectes longiformis is not a suitable biological control agent for the invasive plant Schinus terebinthifolia

Evidence for the influence of conspecific chemical cues on Aphthona nigriscutis (Coleoptera: Chrysomelidae) behaviour and distribution
BioControl - Tập 50 - Trang 343-358 - 2005
Although the distribution of biological control agents may have a significant effect upon their impacts, the mechanisms regulating these distributions are often unknown. Such is the case with Aphthona nigriscutis, a classical biological control agent of leafy spurge in North America. These beetles assume aggregated distributions at some sites but disperse rapidly at others. The potential influence...... hiện toàn bộ
The role of antibiosis and induced systemic resistance, mediated by strains of Pseudomonas chlororaphis, Bacillus cereus and B. amyloliquefaciens, in controlling blackleg disease of canola
BioControl - Tập 56 - Trang 225-235 - 2010
Antibiotic-producing Pseudomonas chlororaphis strains DF190 and PA23, Bacillus cereus strain DFE4 and Bacillus amyloliquefaciens strain DFE16 were tested for elicitation of induced systemic resistance (ISR) and direct antibiosis in control of blackleg in canola caused by the fungal pathogen Leptosphaeria maculans. Inoculation of bacteria 24 h and 48 h prior to the pathogen was crucial for disease ...... hiện toàn bộ

Repeated damage by specialist insects suppresses the growth of a high tolerance invasive tree
BioControl - Tập 61 - Trang 793-801 - 2016
Many invasive plant species have high tolerance to herbivore damage, which can lead to low impacts of introduced biological control insects. High herbivore tolerance may be a trait acquired by invasive plants in their invaded range which makes it difficult to predict impacts of introduced insects. In this study, we compared the growth and foliar secondary chemical responses of invasive and native ...... hiện toàn bộ
Comparative toxicity of some acaricides to the predatory mite, Phytoseiulus persimilis and the twospotted spider mite, Tetranychus urticae
BioControl - Tập 47 - Trang 563-573 - 2002
The relative toxicity of someacaricides to the predatory mite, Phytoseiulus persimilis and the twospottedspider mite, Tetranychus urticae (Acari: Phytoseiidae, Tetranychidae) wasevaluated in laboratory. Five of theacaricides tested, including bifenazate,acequinocyl, chlorfenapyr, flufenoxuron andfenbutatin oxide, were much less toxic to adultfemales and immatures of P. persimilisthan to those of T...... hiện toàn bộ
Recherches sur l'utilisation deVagoiavirus melolonthae pour la lutte microbiologique contre les vers blancs
BioControl - Tập 14 - Trang 349-357 - 1969
Les résultats des infections au laboratoire des larves deM. melolontha par le virus de la ≪sphéroïdose≫ ont fait l'objet d'essais sur le terrain dans la Sarthe. Cette expérimentation, en parcelles, préliminaire à des applications à une échelle plus agricole, a mis en évidence la possibilité d'implantation de la maladie dans un sol non contaminé naturellement et le développement de cell-ci avec le ...... hiện toàn bộ
Incomplete control of the diamondback moth, Plutella xylostella, by the parasitoid Cotesia vestalis in a cabbage field under tropical conditions
BioControl - Tập 59 - Trang 671-679 - 2014
Immature Plutella xylostella (Lepidoptera: Plutellidae) and parasitoids were sampled for 39 months in an unsprayed cabbage field near Cotonou, Benin, to determine how and when host-parasitoid interactions influence the population dynamics of the moth in a tropical environment. Eighty-three samples were taken at approximately two-week intervals. There were no seasonal patterns in the abundance of i...... hiện toàn bộ
