AbstractThe susceptibility of representative pyrethroid (cypermethrin, deltamethrin, lambdacyhalothrin, bifenthrin), organophosphate (chlorpyriphos, triazophos, profenophos) and new chemistry insecticides (spinosad, indoxacarb and emamectin) was investigated for 18 field populations ofPlutella xylostella(Linnaeus) from three different zones in Pakistan. The LC50(mg ml−1; 48 h) values of pyrethroids for various populations ranged from 0.19–1.88 for cypermethrin, 0.31–2.64 for deltamethrin, 0.08–1.16 for lambdacyhalothrin and 0.07–0.88 for bifenthrin. The LC50(mg ml−1; 48 h) of organophosphates ranged from 0.52–5.67 for chlorpyriphos, 0.37–4.14 for triazophos and 0.03–2.65 for profenophos. The most probable reason for low toxicity of organophosphates and pyrethroids is the evolution of multiple resistance mechanisms; however, further studies are required to establish these mechanisms. When these same products were tested against a susceptible laboratory population (Lab-Pak), the new chemistry compounds were significantly more toxic than pyrethroids and organophosphates. The results are discussed in relation to integrated pest management and insecticide resistance management strategies forP. xylostella.

Set Up

Pheromone traps have potential to assist with integrated pest management of diamondback moth (Plutella xylostella (Linnaeus)) Trapping experiments were set up in brassica crops in Canterbury and Auckland to test the potential for improving lures for pheromone traps Catch was improved with higher purity of synthetic lures containing (Z)11hexadecenyl acetate and (Z)11hexadecenal and (Z)11hexadecen1ol (306010) The initial lures tested caught 75 of the number of moths caught in traps baited with virgin females This increased to 2047 using better lures Coupled gas chromatography and electrophysiology confirmed the presence of three active peaks from the chemicals listed above plus a fourth unidentified compound Traps with improved lures were used in a pilot IPM programme in Pukekohe and will assist brassica growers to minimise insecticide usage

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
