- Abstract
The efficacy of native entomopathogenic fungi for biocontrol of Tecia solanivora (Lepidoptera: Gelechiidae) was evaluated in vitro. Native isolates were obtained from infected Premnotrypes vorax, Aepytus sp., Rhinchophorus palmarum, Tecia solanivora, and Pthorimaea operculella larvae and adults, from the localities of Ventaquemada and Umbita (Boyacá) and San Gil (Santander). This work was developed at the Biological Control Laboratory of the Biological Culture Management Group, Tunja, Colombia. Preliminarily, five of seven isolates,which produced higher than 10% mortalities, were selected in vitro: Bv01, Bv03, Bv04, Bv05, and Bv07. According to morphological characterization, the isolates belonged to the Beauveria genus. Efficacy was evaluated on 10 T. solanivora larvae, disinfected and submerged in a suspension of 1x107spores. mL-1. Mortality was quantified every 8 days during 32 days. A completely randomized experimental design was used, with 6 treatments and 4 replicates. Tukey´s probe was used. Results showed that 32 days after treatment application, isolates Bv03 and Bv05 produced the greatest accumulative mortality percentages (7.4 and 8.5%, respectively). We confirm low native fungi pathogenicity against T. solanivora.
