Monitoring: Inspect crops weekly during the vegetative stage and twice weekly from very early budding onwards until crops are no longer susceptible to attack (late podding)... Crops should be scouted for looper eggs and moths to pinpoint the start of infestations and to increase the chance of success of biopesticides such as Bacillus thuringiensis (Bt)... Small loopers (less than 12 mm long) can be controlled with Bt; more than one application may be required...

Loopers can be distinguished from helicoverpa by: their 'looping' action when walking by their body, which tapers to the head they have only two pairs of hind legs, as opposed to four for helicoverpa... Loopers appear susceptible to all insecticides used for helicoverpa control, with the exception of Gemstar and Vivus (NPVs) which only act against helicoverpa... Dipel (Bt) is far more effective against loopers than against helicoverpa but thorough coverage is required for best results...

A number of thrips species can affect peanuts but their damage is minor and infrequent and should not be a problem in irrigated crops... Thrips may also attack flowers which can lead to flower abortion... Control if threshold exceeds 4-6 thrips per flower...

Larger larvae (10-15 mm long) have a pigment free, cream-yellow coloured body that tapers to the rear and a dark, somewhat flattened head capsule... Eggs are initially white and develop a red ring closer to hatching... Use of broad-spectrum insecticides for control often provides poor efficacy and destroys natural enemies, leading to a resurgence of tipworm and outbreaks of secondary pests such as spider mites...
