The susceptibility of field populations of diamondback moth (DBM) Plutella xylostella to lambdacyhalothrin methamidophos spinosad and indoxacarb collected from the four major brassicagrowing regions has been assessed approximately every 2 years from 1997 to 2008 Recent results indicate that populations from all regions have increased their resistance to lambdacyhalothrin but there is little or no resistance to spinosad and indoxacarb and reduced resistance to methamidophos This mitigation of resistance in DBM is attributed to in particular a decadelong regional adherence by the vegetable industry of rotating spinosad with indoxacarb in a twowindowsperyear rotation strategy The original insecticide resistance management rotation strategy had to be updated to incorporate chlorantraniliprole registered as a foliar spray and recently a mixture of chlorantraniliprole and thiamethoxam as a seedling drench Seedling drenches have been removed from the twowindow strategy used for foliar sprays with drenches now aligned with periods targeting the highest pest pressure allowing mode of action (MoA)free periods and rotation of different MoA insecticides to mitigate any resistance buildup in DBM

AbstractDiamides have been used worldwide to manage the diamondback moth (DBM),Plutella xylostellaL. (Lepidoptera: Plutellidae), however some strains showed resistance to these molecules. Also, pheromone traps could be used to manage this pest, hence reducing the use of insecticides in the field. Resistant DBM strains may have biological disadvantages in comparison to susceptible strains in areas without sprays, including reduction in fitness or behavioral changes. Therefore, the aim of this study was to investigate whether DBM strains resistant to chlorantraniliprole showed adaptive costs that could alter male attraction to the sex pheromone, in comparison to susceptible strains in the laboratory and semi-field conditions. First, the LC1, LC10, LC25, and LC50of DBM to chlorantraniliprole were established, which were 0.003, 0.005, 0.007, and 0.011 mg a.i. liter−1, and 5.88, 24.80, 57.22, and 144.87 mg a.i. liter−1for the susceptible and resistant strains, respectively. Development and reproduction of DBM strains subjected to those concentrations were compared. Later, male response to the sex pheromone was investigated in a Y-tube in the laboratory and in a greenhouse to pheromone traps. Resistant DBM strain showed an adaptive cost in comparison to the susceptible strain that can result in a delay in population growth in the field when selection pressure is absent. Conversely, resistant males have no olfactory response alteration in comparison to susceptible males, consistently at 3 (P= 0.6848) and 7 days (P= 0.9140) after release, suggesting that pheromone traps continue to be a viable alternative to manage DBM in an IPM system.

AbstractThe diamondback moth,Plutella xylostella(L.) is the major insect pest of cabbage crops in Togo and Benin. For control, farmers very often resort to spraying chemical insecticides at high dosages with frequent applications. Bioassays were carried out on three populations ofP. xylostella, two from Togo (Kara and Dapaong) and one from Benin (Cotonou), to assess their level of susceptibility to currently used insecticides. A reference strain ofP. xylostellafrom Matuu in Kenya was used as a control. In the laboratory, three insecticide representatives of different chemical families (deltamethrin, chlorpyrifos ethyl and spinosad) were assayed against third instar larvae ofP. xylostella. Results revealed thatP. xylostellapopulations from Dapaong, Kara and Cotonou were more resistant to deltamethrin (13 to 59-fold at LC50level, 149 to 1772-fold at LC90level) and chlorpyrifos ethyl (5 to 15-fold at LC50level, 9 to 885-fold at LC90level) than the reference strain. Spinosad was more toxic toP. xylostellapopulations than the other insecticides with LC50and LC90values less than 1 µg/ml and 15 µg/ml, respectively. However, the population from Cotonou appeared significantly more resistant to spinosad compared to the reference strain. These results are discussed in the light of developing an integrated pest management strategy for reducing the selection pressure of spinosad.
