Pale cotton stainer, Dysdercus sisae, adult showing markings.. Reduced insecticide use in Bollgard transgenic crops and uptake of integrated pest management (IPM) may result in the cotton stainer becoming a more frequent pest... Damage can be assessed regularly from boll set to boll maturity, by randomly selecting 14-day-old bolls, and squashing them into the palm of the hand to look for the presence of warts or stained lint...

Lucerne leafhoppers are phloem feeders and inject a toxin, causing leaves to turn yellow and burn off (die) from the tips... Severe infestations of the lucerne jassid can stunt plant growth and reduce yield, but even high vegetable jassid populations have negligible if any effect on yield... Only control vegetable leafhoppers if more than 25 hoppers per single sweep over a single row (90 cm spacing)...
