Abstract:

This work was performed in Tijuana, Baja California, Mexico, from October 2012 to January 2013. The work aimed to evaluate the effectiveness of two different traps and the SuzukiiTrap® attractant in the catch of Drosophila suzukii. The monitoring of pest confirmed the presence of spotted-wing drosophila (Drosophila suzukii Mats.) in the territory of Baja California, Mexico. This fly had a population peak of females in November 2012 in proportion (2:1) respect to the total of flies and a lower incidence of both sexes in January 2013. D. suzukii could be monitored by red traps, followed by yellow traps, with SuzukiiTrap® attractant. These yellow traps, slighly exceeded the control capture with vinegar. All traps that used the SuzukiiTrap® attractant take longer time before to be rebaiting again, while the traps with vinegar were loaded in shorter time. The relationship between the insects captured by red traps in different types of host such as citrus (Citrus spp.), guava (Psidium guajava L.), ornamentals (alternative host) and loquat (Eribotrya japonica) was significanly higher, followed by the artisanal traps with vinegar, that had better correlation with peach (Prunus persica L.), guava (Psidium guajava L.) and grape (Vitis vinífera L.), while the yellow traps were only associated with ornamentals (alternative host). The guava (P. guajava L.) was the plant species most dangerously infested during monitoring of this pest. However, this is not included in the register host of D. suzuki in Mexico. As to the weather conditions, it was observed that maximum temperature did not appear to influence negatively on populations of D. suzukii. It was also observed that female have adaptability to environmental changes. However, the difference between maximum and minimum temperatures over 14°C had a negative influence on the total number of insects collected and males, which occurred by the abrupt decline in temperature and frost of December.
