New findings on the biology and control of Mandalotus weevils including insecticide trials.. In recent seasons, wetter weather patterns and some good winter rainfall has largely reduced pest pressure on established crops in winter and spring, and in both 2010 and 2011 there were fewer reports of damage from spring pests such as aphids, diamondback moth, and native budworm (Table 1)... Efficacy was assessed by releasing marked weevils after the plots had been treated with insecticide (within 28 hours) into cages in the centre of plots for 7 days and afterwards assessing recovered weevils as alive, moribund (unable to feed) or dead...

MANDALOTUS WEEVILS ACTIVE: As Mandalotus weevils become active in parts of South Australia's grain belt, growers are advised that early detection is critical in preventing and reducing damage to germinating crops... According to the South Australian Research and Development Institute (SARDI) Entomology Unit, the weevils have been reported actively feeding in the Murraylands and on Yorke Peninsula... Adults are known to attack seedlings of canola, lentils, beans, cereals, and medic pasture, with canola most susceptible to serious damage," said Mr Perry, whose work is supported by growers and the Australian Government through the Grains Research and Development Corporation's (GRDC) investment in the National Invertebrate Pest Initiative (NIPI).

Canola growers urged to check for destructive weevils As canola crops emerge and establish across the southern grain-growing region, growers are advised to keep an eye out for destructive Mandalotus weevils... The weevils have become an increasingly serious pest of young canola crops on lighter soil types, and early detection is critical in preventing and reducing damage to germinating plants... Mr Perry said little was previously known about the pest's basic biology, but the study is already revealing more about the number of species involved, their life history and host range - information which is critical for developing effective management strategies...
