Currently, Ecuador is one of the largest exporters of nectar from this fruit. The increase in monocultures such as passion fruit cultivation leads to the proliferation of insect pests. Dasiops inedulils is one of the insects present in the passion fruit crop, registering damage close to 90%. The damage is caused by the larvae. These begin by consuming the anthers, there they continue with the part of the ovary, causing the flower bud, preferably 1 to 2 cm in size, to fall. The damage caused by D. inedulis to the passion fruit flower is due to the action of larval feeding on the flower in formation. Feeding on anthers and stamens causes losses of up to 90%. Control tests against D. inedulis should be carried out when 30% of flower buds are attacked or 0.5 fly trap measurements per day. Four control measures for D. inedulis are reported in this work. Natural biological control, cultural control, control by plant extracts and chemical control are used against D. inedulis. The cultural control method is the method with low environmental impact and can be combined with the other types of methods carried out to reduce the natural population of the flower bud fly D. inedulis in the passion fruit crop. |
