Mr McMaster says growers should practice good broadleaf weed control in and around crop areas as SLW has a very wide host range and can rapidly develop resistance to insecticides. ".. Queensland Department of Primary Industries and Fisheries (QDPI&F) entomologists have visited the area and also report cotton fields around St George are at or reaching high densities of SLW. QDPI&F graduate entomologist Zara Ludgate says the whitefly present in the.. Greenhouse whitefly (GHW) and East Australian native whitefly have been common in the past but are easy to control compared with SLW. "It is thought that increased host plant availability from a wet winter/spring, warm conditions and a decline in natural enemies due to the use of broad spectrum insecticides has contributed to the high SLW numbers," Ms Ludgate said...

The four types of whitefly found in Australia are: the greenhouse whitefly , Trialeurodes vaporariorum the silverleaf whitefly (SLW), or B biotype, Bemisia tabaci species complex the Australian native (AN), biotype Bemisia tabaci species complex , also known as the cotton whitefly... The greenhouse whitefly has overlapping wings that form a heart shape... B biotype poses a greater pest threat than other whitefly because of their greater host range, quicker reproductive rate, and ability to rapidly develop resistance to insecticides...

A significant problem in the management of SLW is its ability to develop resistance very quickly to many insecticides when used repeatedly... SLW management in Queensland cotton will be based on a number of integrated controls such as: breaks in the cropping cycle and elimination of alternative hosts use of economic thresholds to determine whether control action with an insecticide is necessary use of appropriate insecticides such as insect growth regulators (IGRs) as required conservation of natural enemies an insecticide management to conserve susceptibility...
