Variação na diversidade de insetos durante a primavera em cultivo orgânico de morango

Abstract

Organic strawberry crops requires new pest management strategies. One is the conservation of natural enemies already existing in the agroecosystem. To elaborate actions of this nature, it is necessary to know beforehand which organisms are present in the crop environment. The objective of this work was to know the diversity of insects associated with strawberry during the spring of 2018. We conducted the experiment in an experimental area of the Federal University of Southern Frontier, in Laranjeiras do Sul, Paraná, Brazil, in two strawberry cropfields of Pircinque and Jonica. We used pitfall and Moericke traps to collect the insects, and then quantified and identified them in laboratory. We captured 4022 insects in total, distributed in 8 orders and 63 families. To estimate diversity, the Shannon-Wiener index was used. The diversity was higher on October, when the culture was in reproductive period. Further studies are needed to determine what are the predominant conditions for the permanence of these organisms in the crop environment.
