“…Among the benefits offered by these microorganisms are their safety to human beings and animals, their relatively high specificity and the absence of the development of resistance in target organisms. Moreover, the efficiency of these microorganisms to control important pests has been proven in multiple studies (Li et al, 2010;Lacey et al, 2011;Pelizza et al, 2012;Reddy et al, 2014). A crucial step prior to its use as an insecticide is the formulation, which should assure the viability and pathogenicity of infective units during storage and after application and should improve the product form for ease of application (Jackson et al, 2010).…”

V.E. Sy, S. Schalamuk, A.C. Scorsetti, and I.L. Botto. 2016. Volcanic materials as carriers for the formulation of mycoinsecticides using the fungus Beauveria bassiana. Cien. Inv. Agr. 43(2):273-282. Improvements in the formulation of biological insecticides are crucial to increase their stability and competitiveness in the market. The aim of this work was to evaluate the use of volcanic materials with different hydric retention capacities to increase the thermotolerance of B. bassiana conidia. Two pyroclastic rocks and a zeolite clinoptilolite were selected for this study. In addition, a commercial silica gel was used due to its reported capacity to increase conidial thermotolerance. Dry conidia were mixed with the materials to obtain a 2% w/w granular formulation, while conidial powder alone served as the control. Mixtures were stored at room temperature for 30 days and then exposed to 50 ºC for two hours, and the viability was measured before and after the thermal exposure. No significant decrease in viability was observed for conidia stored with any of the pyroclastic materials, while the germination was reduced by 10, 17 and 23% for unformulated conidia, conidia stored with silica gel and conidia stored with zeolite, respectively. From these results, a pyroclastic rock was selected to test its capacity to maintain high viability under different temperatures (4, 25 and 35 ºC) and humidities (~0 and 20%). A decrease in viability was observed with an increase of temperature, and lower viability was also recorded in humid treatments, but only at 25 and 35 ºC.

The cotton stainer bug Dysdercus peruvianus (Hemiptera: Pyrrhocoridae) is an insect pest that causes heavy losses in cotton plantations. The need to reduce the use of insecticides for control of this pest has increased steadily, and Metarhizium anisopliae (Ascomycota: Clavicipitaceae) could be an important biopesticide candidate to control this pest. The effect of M. anisopliae on D. peruvianus nymphs and adults using formulations with soybean oil and Agral Ò was evaluated. Formulation using 10% soybean oil added to 10 8 conidia mL -1 (grown on used and reused rice) was the most effective for nymph and adult, causing 100% mortality 6 and 7 days after exposure, respectively. The SEM analysis of infected insects showed that M. anisopliae conidia were able to adhere anywhere on the exoskeleton, but were more abundant between the joints. Using the same rice for two batches of growth may be an option for improving commercial conidial production of M. anisopliae and may reduce overall costs. Its effect on D. peruvianus adults opens a new possibility for using this fungus as an alternative to chemical pesticides and the use of M. anisopliae in association with integrate pest management.

“…The majority of products are based on the ascomycetes Beauveria bassiana or Metarhizium anisopliae. The largest single country of use is Brazil, where commercial biopesticides based on M. anisopliae are used against spittlebugs on around 750 000 ha of sugarcane and 250 000 ha of grassland annually [28]. The fungus has also been developed for the control of locust and grasshopper pests in Africa and Australia [29] and is recommended by the Food and Agriculture Organization of the United Nations (FAO) for locust management [30].…”

Over the past 50 years, crop protection has relied heavily on synthetic chemical pesticides, but their availability is now declining as a result of new legislation and the evolution of resistance in pest populations. Therefore, alternative pest management tactics are needed. Biopesticides are pest management agents based on living micro-organisms or natural products. They have proven potential for pest management and they are being used across the world. However, they are regulated by systems designed originally for chemical pesticides that have created market entry barriers by imposing burdensome costs on the biopesticide industry. There are also significant technical barriers to making biopesticides more effective. In the European Union, a greater emphasis on Integrated Pest Management (IPM) as part of agricultural policy may lead to innovations in the way that biopesticides are regulated. There are also new opportunities for developing biopesticides in IPM by combining ecological science with post-genomics technologies. The new biopesticide products that will result from this research will bring with them new regulatory and economic challenges that must be addressed through joint working between social and natural scientists, policy makers and industry.
