“…L.) está presente na região do Submédio do São Francisco, sendo visitada por M. mandacaia durante o forrageamento para coleta de pólen e néctar. Nessas culturas é comum o uso de acefato, um tipo de agrotóxico, sendo que ele pode levar à mortandade de até 90% das abelhas quando expostas a ele em um período de um dia (Gassen, 2008;Bovi, 2013).…”

The objectives were to evaluate the efficiency of entomopathogenic fungi against Plutella xylostella (L.) and the compatibility of the most virulent isolates with some of the insecticides registered for use on cabbage crops. Pathogenicity tests used isolates of Beauveria bassiana, Metarhizium rileyi, Isaria fumosorosea, Isaria sinclairii, and Lecanicillium muscarium standardized at a concentration of 10(7) conidia/ml. Cabbage leaf discs were immersed in these suspensions, and after evaporation of the excess water, were placed 10 second-instar larvae of P. xylostella, totaling 10 leaf discs per treatment. Mortality was assessed 7 d after treatment, and the isolates that caused mortality>80% were used to estimate LC50 and LT50. The compatibilities of the most virulent isolates and the insecticides were tested from the mixture of these into the culture medium, and after solidifying, the medium was inoculated with an aliquot of the isolated suspension. The following parameters were evaluated: growth of the colony, number and viability of conidia after 7 d. The isolated IBCB01, IBCB18, IBCB66, and IBCB87 of B. bassiana, LCMAP101 of M. rileyi, and ARSEF7973 of I. sinclairii caused mortality between 80 and 100%, with LC50 and LT50 between 2.504 to 6.775×10(4) conidia/ml and 52.22 to 112.13 h, respectively. The active ingredients thiamethoxam and azadirachtin were compatible with the entomopathogenic fungi. The results suggest that the use of these isolates is an important alternative in the pesticidal management of P. xylostella, with the possible exception of the associated use of chemical controls using the active ingredients thiamethoxam or azadirachtin.

ABSTRACT:The differences in the toxicity of pesticides, herbicides and ripeners for isolates AM 09, JAB 07, IBCB 07 e JAB 46 of Beauveria bassiana were evaluated through experiments conducted in culture medium. The isolates were cultured on potato dextrose agar (PDA) containing agrochemicals. Germination, growth and sporulation were evaluated and, based on these parameters, the toxicological classification of pesticides for each isolate was made. The insecticide Actara® was considered compatible with AM 09, moderately toxic for JAB 07 and toxic for IBCB 07 and JAB 46. Regente WG 800® was considered compatible with all isolates, while Temik 150® showed to be toxic. In relation to the herbicides, the product Glifosato Nortox® was considered compatible with AM 09, moderately toxic for IBCB 07 and JAB 46 and toxic for JAB 07. Plateau® was classified as moderately toxic for AM 09 and JAB 07, and toxic for IBCB 07 and JAB 46. Contain®, DMA®, Karmex®, Sencor 480® e Velpar-K® were classified as toxic for all isolates. In the case of ripeners, both Curavial K® and Moddus® showed to be toxic for all the isolates. The results revealed that there is variation between isolates of B. bassiana regarding the toxicity profile of agrochemicals. AM 09 was the most tolerant to the toxic action of the products. Germination suffered minor effect than growth and sporulation, and JAB 07 was the isolate less affected by agrochemicals with regard to this parameter.
