Biological control against the European Corn Borer with trichogramma has quickly increased since a single release method was marketed in 1997. More than 80.000 ha, representing 20% of the overall area of maize treated against this pest in France, are now protected with this environment-friendly technique. Over the last two years BIOTOP company...

The introduction of the single release method for trichogramma used against the European corn borer in France, has allowed a dramatically increase of treated corn areas from 32.000 ha in 1997 to more than 65.000 ha in 2001. This technique is supported by a favourable context at the moment, however its development is mainly due to continuous...

The predatory mite Neoseiulus cucumeris is an efficient beneficial against thrips. This study aims to develop a preventive control method against the thrips Frankliniella occidentalis in integrated production of roses in greenhouse. At the same time, the assumption of obtaining a better efficiency by increasing the frequency of releases and by...

Trichogramma (Hymenoptera: Trichogrammatidae) are species used worldwide for the biological control of Lepidopteran pests, notably through inundative releases on millions of hectares. The optimal use of Trichogramma parasitoids in crop protection requires an accurate knowledge of their biology. More specifically, the importance of age factor in...

Although many studies of lindane toxicity have been carried out, we still know little about the underlying molecular mechanisms. We used a microarray specifically designed for studies of the hepatotoxic effects of xenobiotics to evaluate the effects of lindane on specific gene expression in primary cultured rat hepatocytes. These genes were...

The tomato fruitworm, Helicoverpa armigera (Hubner), is a major pest in processing tomato crops in Tunisia. The dynamics of fruitworm populations in the field is important in order to enhance the efficiency of insecticides. Seasonal activity was studied by sampling methods on foliage and by pheromone traps over a three year period. Two traps...

Thrips species Frankliniella occidentalis and Thrips tabaci [Thysanoptera: Thripidae] are two important pests of greenhouse rose crops in the south of France. Thrips catches on yellow traps placed outside reach their peak 2 to 3 weeks before the thrips infestation peaks inside the greenhouse. The rapid increase in the number of thrips captured...

A single microsatellite marker was used to distinguish between strains of Trichogramma cacoeciae Marchal collected from the carob moth ( Ectomyelois ceratoniae) in Tunisia and from the grapevine moth ( Lobesia botrana) and a hawk moth in France. This marker can be used as an identification and monitoring tool in pest management programs.

The tomato leafminer Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) has recently invaded Mediterranean countries and is a major pest in tomato crops. Trichogrammatid oophagous parasitoids have shown promising potential for controlling the pest before the yield decreases in the greenhouse. In protected tomato crops (greenhouse), mirid...

Frankliniella occidentalis (Pergande) is a key pest of various crops worldwide. In this study, we analyse the dependence of the infestation of this pest on spatially distributed micro climatic factors in a rose greenhouse. Despite the importance of this subject, the few existing studies have been realized in laboratory rather than in greenhouse...

Thrips are widespread pests in ornamental greenhouses in France. The survey of thrips populations in greenhouses on rose and gerbera crops in two sites in Southern France, at the INRA Research Center (Sophia-Antipolis, France) and at the CREAT Experimental Center (Nice, France), were performed from 2006 to 2009. During that period, more than...
