The orange wheat blossom midge, Sitodiplosis mosellana (Géhin), can significantly reduce wheat yield. Growing resistant wheat cultivars is an effective way of managing this pest. The assessment of cultivar resistance in field trials is difficult because of unequal pressure of S. mosellana caused by differences in cultivar heading dates relative to the flight period of S. mosellana adult females and huge variations of egg laying conditions from 1 day to another. To overcome these hurdles and to expose all cultivars homogeneously to the pest, an assessment method of cultivar resistance was developed under semi-field conditions. In 2015, the resistance of 64 winter wheat cultivars to S. mosellana was assessed. Few or no larvae developed in the ears of resistant cultivars, but in susceptible cultivars, large numbers of larvae developed. Seventeen cultivars proved to be resistant, whereas 47 were susceptible. The identification of new resistant cultivars offers more opportunities to manage S. mosellana. The phenotyping method is easy, cheap, efficient and reliable. It can be used to guide the breeding of new resistant wheat cultivars. Using specific midge populations, this method could also be used in research on new resistance mechanisms in winter wheat or in other cereal species. [less ▲]

Agronomists often underestimate the damage inflicted by the orange wheat blossom midge, Sitodiplosis mosellana (Géhin), a wheat (Triticum aestivum L.) pest. The main risk arises when the emergence of the adult midges coincides with wheat ear emergence. The emergence of adult midges was monitored in Belgium over four years and analysed against climate data, establishing the significance of specific rainfall events as triggers for the final phase of development prior to emergence. This discovery, combined with experience from previous models, was incorporated into a new forecasting model, described in this paper. The new model consists of three separate phases. The first phase comprised a temperature accumulation of 250 degree-days (DD) above 3°C, starting from 1 January. Once this initial condition is satisfied, the second phase starts, and it lasts until the occurrence of a double signal consisting of a rise in the mean daily temperature up to 13°C, followed by rainfall. This rainfall event triggers an accumulation phase of 160 DD above 7°C. Once this last condition is met, the adults emerge. [less ▲]

Varietal resistance is an effective control method against orange wheat blossom midge, Sitodiplosis mosellana (Géhin). The determination of the resistance degree through field trials is hindered by the homogeneity lack of the exposure to the insects due to the variation in the date of heading of various varieties. To overcome this obstacle, a novel method has been developed, where the varieties sown in containers are placed in greenhouse at the approach of heading, and covered with a veil. Starting from the appearance of first ears, and for ten days, young adults of S. mosellana are released into the se enclosures. The degree of resistance is measured from the number of larvae that developed in the ears. This easy, economical and reliable method, benefits from the recent advances of knowledge in the biological cycle of S. mosellana, which allow to induce the emergence of young adults ready to lay eggs over several weeks.
