Abstract: The control of insects associated with home garden vegetable crops is usually done by sintetic pesticides. However, the risks of the indiscriminate use of pesticides on human health and the environment need to be considered. The objective of this work was to study the attractive effect of natural substances on D. speciosa, a very important pest in Latin America. The following treatments were tested: roots of Cayaponia sp., green fruits of Lagenaria sp., water extract of Brassica pekinensis, extract of fermented fruits, red vinegar and water as a control. The experimental design was randomized blocks with six replications. All the tested substances were put into PET plastic bottles of 2L with eight lateral holes and distributed at random in the experimental area. Green fruits of Lagenaria sp. captured the larger number of D. speciosa, 5.4 times more than roots of Cayaponia sp. that captured 19.7 times more than the control tratament. The water extract of Brassica pekinensis had no effect on D. speciosa attraction, and did not differ from the control treatment in the number of captured insects. Independently of the treatment, the population peak of D. speciosa occurred in February and March.
