“…Although B. bassiana has been identified by several authors as a potential control agent for A. diaperinus (Crawford et al, 1998;Geden & Steinkraus, 2003;Oliveira et al, 2014), its efficiency under field conditions in Brazil was only recently shown (Alves et al in press). Therefore, there are no available studies evaluating the compatibility of this microbial agent with the chemical insecticides used to control insect populations in Brazilian poultry production systems.…”

The control of Alphitobius diaperinus is based mainly on chemical insecticides, and the indiscriminate and incorrect use of these products has led to failures in insect control. Thus, it is important to monitor the efficiency of the products available on the market and to develop alternative insect control strategies. The present study evaluated the effect of a new product (cypermethrin-6%) under laboratory and field conditions and assessed its in-vitro compatibility with the fungus Beauveria bassiana (Unioeste 4 isolate). Its efficiency in dry powder and wettable powder formulations was also assessed in the laboratory through comparison with a similar insecticide (cypermethrin-5%) at five different concentrations. The field assays were conducted in two commercial broiler breeder houses (Treated and Control), applying the new product on the litter at the manufacturer's recommended concentration (RC). Germination, vegetative growth, conidial production, number of colony forming units (CFUs) and insecticidal activity of the fungus were used to evaluate the compatibility of the insecticide. The effects of the cypermethrin-6% product and cypermethrin-5% were equivalent in the laboratory, and the new product exhibited better performance at lower concentrations (¼RC, ⅛RC). The strategy applied in the field reduced the insect population in up to 96% after 75 days. Additionally, all concentrations of cypermethrin-6% were compatible with the fungus under the evaluated in-vitro conditions. Therefore, the new product is considered selective for B. bassiana. Further studies are necessary to assess its compatibility under field conditions, consolidating this strategy as a viable alternative for managing this pest.

“…Maior suscetibilidade larval do cascudinho para B. bassiana também foi observada por Steinkraus et al (1991), Crawford et al (1998) e por Geden et al (1998). Mais recentemente, Chernaki-Leffer (2004) também avaliou a suscetibilidade de A. diaperinus a fungos entomopatogênicos, verificando também maior suscetibilidade larval.…”

Vuill. and Metarhizium anisopliae (Metsch) Virulence against the Lesser Mealworm Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae)ABSTRACT -This study was carried out to evaluate the influence of temperature and poultry litter on germination vegetative growth virulence and conidial production of Beauveria bassiana (Bals.) Vuill. and Metarhizium anisopliae (Metsch.) isolates on larvae and adults of the lesser mealworm (Alphitobius diaperinus) (Panzer). The vegetative growth and conidial production were evaluated on culture media. Virulence was studied submerging larvae and adults in a conidial suspension (1 x 10 8 conidia/ml). All the experiments were carried out in growth chamber (26ºC and 32ºC and 14h photophase). Fungus-killed insects were daily collected and used for microscopic conidial counts. The poultry litter effect was evaluated by submerging the insects in a fungal suspension (10 8 conidia/ml) and then transferring them to cups containing poultry litter (new and used). B. bassiana isolates were more sensitive than M. anisopliae to high temperature because conidia viability, vegetative growth and virulence were negatively affected (P < 0,05). The conidial production was higher to B. bassiana in 26ºC (7 to 11 x 10 8 conidia/larval cadaver and 8 x 10 8 conidia/adult cadaver) (P < 0,05). Larval stage was about 10 times more sensitive to M. anisopliae at 26ºC than adults stage. Regarding B. bassiana, differences on sensitivity between larval stages and adults were not observed at this temperature. However, at 32ºC, larval stage was more sensitive for CB116 and UEL50 isolates. Mortality was higher when larvae and adults (15.7 and 66.7% respectively) were treated by B. bassiana and maintained on new poultry litter at 26ºC) (P < 0,05).KEY WORDS: Entomopathogenic fungus, microbial control, animal production RESUMO -O estudo avaliou a influência da temperatura e de cama nova e usada na germinação, crescimento vegetativo, virulência e produção de conídios de isolados de Beauveria bassiana (Bals.) Vuill. e Metarhizium anisopliae (Metsch.) sobre larvas e adultos do cascudinho Alphitobius diaperinus (Panzer). O crescimento vegetativo e a produção de conídios foram avaliados em meio de cultura. Para a avaliação da virulência os insetos foram tratados com suspensões contendo 1 x 10 8 conídios/ ml. Os experimentos foram realizados em câmara B.O.D. (26ºC e 32ºC e 14h de fotofase). Diariamente os insetos mortos foram coletados para quantificação da produção de conídios. Para avaliação das camas, após a inoculação, insetos foram transferidos para recipientes contendo cama de aviário (nova e usada). Os isolados de B. bassiana foram mais sensíveis à temperatura elevada em relação aos isolados de M. anisopliae no que se refere à viabilidade, crescimento vegetativo e virulência (P < 0,05). A conidiogênese também foi maior para B. bassiana a 26ºC (7 a 11 x 10...
