Avaliação populacional de artrópodes na cultura do pepino utilizando armadilhas do tipo moericke e pitfall

Abstract

Cucumber is an important and representative vegetable across the country. As food it is usually consumed "in natura", however, in the industry sector it’s used for the production of cosmetics and drugs. The vegetable is a host of a large number of insects and mites, having as key pests individuals from the Orders Hemiptera, Thysanoptera, Lepidoptera, particularly. The objective of this study was to evaluate the population of arthropods in the cucumber crop using Moericke (air) and Pitfall (soil) traps. Cucumber seedlings were obtained commercially and grown in the experimental area of the Federal University of Fronteira Sul, Campus Chapecó, Santa Catarina. Three samplings were conducted from October to December, 2015. The sampled individuals were screened and identified at taxon Order and placed in vials containing alcohol [70%]. A total of 1651 individuals divided into 11 groups were collected throughout the work. Soil traps were the ones that had the highest number of Orders (9) and specimen (in 1309) caught, being the Order Hymenoptera (928) the most abundant one. In Moericke traps (air), 342 individuals were captured and distributed in eight orders, having the Order Diptera as the most abundant (153). The Moericke trap got to the Shannon diversity index a value of 1,53. Regarding the Pitfall trap, the Shannon diversity index value corresponded to 1.02.
