Successful Control of Chilo suppressalis By Bioglobal's Newly Developed Mating Disruption Product

The rice stem borer (RSB), Chilo suppresslis, is one of most destructive pests in rice farming. RSB occurs in East Asia, South Asia, and Europe. It has many overwintering sites and develops several generations in the rice growing period, which can easily result in serious generation overlapping. Heavily relying on chemical insecticides to control this pest has already led to its increasing resistance to insecticides. Controlling this pest has become a rising challenge. Searching for alternative solutions is pressing in the plant industry. Using sex pheromones to disrupt the mating of this pest has been widely viewed as a promising alternative.

In the past four years, Bioglobal has conducted large-scale field trials of its newly developed RSB mating disruption product in Hunan, Anhui, Zhejiang, Shanghai, Hebei, and other provinces in China. The product is a plastic tube dispenser that provides seasonal long protection. Long field activity is ideal and crucial to control pests with multiple generations and serious generation overlapping, like RSB. Different levels of dosages and different field deployments of this product have also been tested. These trials show the mating disruption rate of adult RSB could reach over 95%, and hence, it could significantly prevent the occurrence of withered sheaths, withered hearts, and white spikes caused by RSB in rice fields. This mating disruption could increase rice yields by 20% to 30%. In addition, because of its different modes of action, this product can be used as an alternative to manage RSB resistance to chemical insecticides.

Bioglobal has started product registration of this mating disruption product and expects to finish the registration in 2025.
