Attractive food in the sampling and seasonality of insects in soybean-oats succession

Abstract: The objective of this work was to evaluate the fluctuation and population density of different families of insects by means of attractive food based on oleoresins and sugars in an area under soybean-oat succession. The experiment was carried out in the municipality of Cruz Alta, RS, according to Koppen type Cfa. During the months of March to September, 9 traps were installed with the alimentary attraction around an area of 10.5 hectares, the samplings in the traps were realized every two weeks, being the numbe… Show more

“…The low diversity of species is due to the continuous crop succession system (soybean-corn for five years), where the fittest are more abundant, whereas the species with the least adaptation tend to migrate or are unable to establish in this system. Studies indicate that cropping systems with crop succession, rather than rotation, tend to accumulate certain herbivorous insect species to the detriment of others (ENGEL et al, 2019).…”
