Minor cucurbit pests
Farmer's Weekly
|Farmer's Weekly 6+13 January 2023
Bill Kerr looks at the leaf miner, cucurbit ladybird beetle and African bollworm, all of which, despite being minor pests, can cause damage.
This article explores three pests of cucurbits that are of lesser importance, but that nonetheless are still threats to be taken seriously.
LEAF MINER
The main leaf miner in South Africa is Liriomyza huidobrensis, and when it first appeared in South Africa it created alarm. I even found the larvae burrowing down the stems of newly emerged seedlings.
Fortunately, parasitoids (parasitic wasps) can keep this pest largely under control, provided they are allowed to do so! I have seen L. huidobrensis inflict substantial damage on farms where a harsh chemical is used to kill it, because the same spray then also kills the parasitoids.
