Resumo(s)
The insects present in the blackberry and blueberry crops are still almost
unknown in Portugal. Thrips and their natural enemies were surveyed in these crops,
during the flowering period, in Odemira region, as well as in the weeds inside and
around the crops areas. This allows an evaluation of the entomological interaction cropweeds,
for a future management of weeds taking also into account crops protection
against pests. The preliminary results obtained are presented. Thrips flavus and T. tabaci
were the most abundant thrips in the crops. Weeds where Thrips sp. adults were more
abundant were Arctotheca calendula, Crepis capillaris, Senecio gallicus, Geranium
molle, Malva parviflora, Lavatera cretica and Lupinus luteus. In this last weed species,
Aeolothrips spp. predators were abundant. The heteropterans Orius sp., predators of
thrips, were detected in the blackberry crop, and also on Conyza bonariensis, Conyza
sumatrensis, Sonchus tenerrimus and Echium plantagineum
