Control was ineffective in beans containing later weevil instars at time of harvest. To find out, separate several handfuls of beans from the rest of the beans. 0000015288 00000 n Reply . Finally, the researchers used statistical analyses to find genetic signals–called markers–that are more common in the DNA of bean plants resistant to weevils. 0000055011 00000 n 0000010965 00000 n A single introduction of the parasitoid D. basalis (five males and five females per kg bean seeds) in the first week following harvest resulted in weevil eradication on four farms with a low level of initial infestation. 0000001628 00000 n 0000003882 00000 n H�b```f``���$�11 �P������ ��X�qIA�����h�a`X�6=�m The study confirmed that weevil resistance in beans is genetic.

Some of the most common host plants of pea weevil include dry bean, faba beans, field pea, and perennial legumes. Proper soil preparation and planting can prevent most weevil infestations, but control pea weevils with natural means or pesticide applications if they are causing serious damage.
