Fungos entomopatogênicos: uma revisão sobre a espécie paecilomyces lilacinus no controle de pragas na agricultura

Abstract

This study examines the use of entomopathogenic fungi of the species Paecilomyces Lilacinus in the control of pests in agriculture. The objective was to describe the importance of the fungus P. Lilacinus in the control of pests in agriculture, based on studies already published in the literature, and to emphasize the importance of the search for new sources as an alternative to the existing biological control. The use of biological products has become one of the most discussed and viable means or alternatives in the control of pests, since it is the alternative that has more advantages than the chemical agent, taking into account that it is a practice that when contaminated does not unbalance the environment or leave residues, with low cost and easy applicability. Among this diversity of known egg-parasitic fungi, only two species have been better studied: Pochonia chlamydosporia and Paecilomyces lilacinus due to the promising results they have presented. The survey showed that the species P. lilacinus has a great capacity to reduce infections caused by some agents, combined with survival in the soil, which are factors to be considered in the selection of biocontrol agents. Thus, the use of the species P. lilacinus is recommended in areas that may be affected by agents that cause damage to the soil and plants, thus seeking to reestablish the natural balance in the soil and by extension, increase the suppressive effect on pests
