Diadegma semiclausum is an important larval parasitoid of diamondback moth Plutella xylostella Little was known about the reproductive biology of this parasitoid The present study investigated mating behaviour and egg maturation dynamics of D semiclausum in the laboratory at 211C 168 h (lightdark) and 5060 RH Both males and females became sexually mature

Diadegma semiclausum is an important larval parasitoid of diamondback moth (DBM) Plutella xylostella The present study investigated the reproductive fitness of D semiclausum females in response to host densities of 5 and 30 DBM larvae per cabbage seedling per day Both the number of hosts parasitised and the number of female progeny produced over the life of the parasitoid were significantly greater in the 30 than the 5 host density (hosts parasitised 60131 versus 12015 and female progeny produced 6710 versus 122) (P

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
