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 silverleaf whitefly (SLW - Bemisia tabaci B-biotype) has developed into an important problem pest in cotton... SLW secretes a sticky honeydew that can contaminate cotton lint once there are open bolls in the crop (Figure 1)... In summary, the key take-home messages for managing SLW in soybeans are (a) adopt the go soft early spray strategy, (b) observe mirid thresholds, and (c) avoid late plantings in regions with a history of high late season SLW pressure...
