Bibliographic Details
Summary:In an assay performed in November 2010, adults captured in sexual pheromone water traps with and without light were counted. In traps with light a part of the insects were sampled for sex identification. Water traps for mass trapping which combined the attractive effect of sexual pheromone and light captured higher levels of Tuta absoluta adults than the traditional ones, with pheromone bait only. However, these traps were unable to capture females of T. absoluta (about 1.1% of the captured adults were females), an expected event due to the light effect. Although capturing higher number of males of T. absoluta, the lack of female captures makes it hard to justify the use of these traps, considering its high cost compared with conventional pheromone water traps.
