Using Semiochemicals and other biologicals to control Tomato Leafminer (TLM)

The Tomato Leafminer (Tuta absoluta - Lepidoptera:Gelechiidae) is also known by the common names of South American tomato pinworm, tomato pinworm, and South American tomato moth. It is a serious pest of tomato crops in most areas worldwide. In recent years, it has become an invasive species in China. The Chinese Ministry of Agriculture is seeking experts' opinions to determine whether this insect shall be classified as a Category One Pest, which, according to the PRC Regulations on Control of Agricultural Diseases and Pests, means TLM is a pest that occurs all year long in large areas or may cause severe damages on agricultural farming.

The Bioglobal R&D team has been preparing biologicals to monitor and control this insect for four years. While researching and manufacturing sex pheromone lures for monitoring this insect, Bioglobal has been using repelling agents and kairomone-based attractants. The repelling agent works to deter TLM from approaching or landing on a tomato, and the kairomone-based attractants lure the male and female adults of TLM and kill them with sticky cards or drown them in the water contained in basins. The three-year trials in Yunnan Province and other places indicate positive results that these Innovative control measures may work well.

Additionally, Bioglobal has also begun experimenting with TLM pheromone-based mating disruption dispensers, intending to provide a seasonal long management solution.
