- Description
- False codling moth, Thaumatotibia leucotreta(Meyrick, 1913) (Lepidoptera: Tortricidae), is animportant pest on citrus in South Africa. Several new insecticides were screened for theirpotential negative impacts onT. leucotreta’s reproduction through topical insecticide applica-tions and detached fruit bioassays. Detached fruit bioassays showed that the registeredstandard concentration of Delegate®20 g/100 l and DPX-HGW86 35 ml/100 l caused femalesto oviposit significantly fewer eggs (P= 0.0016) than the controls. The same was found forthe registered concentration of Coragen® (P is less than 0.0001). Topical insecticide trials showed thatonly concentrations of Coragen®, at the registered field rate and above had an effect on themoths’ reproductive output (P is less than 0.0001). Alsystin®and Meothrin™, which were used asindustry standards, did not negatively affect the reproductive output of the moths duringtopical or detached fruit bioassay trials. This study helps to better understand the impor-tance of the application mode,i.e.directly on moths or fruit and implies secondary benefits tosome insecticide applications.
