“…The fungus Beauveria bassiana was efficient in to cause vitro mortality of Helicoverpa zea (Zambiazzi et al, 2016). The species Beauveria Bassiana and Metarhizium anisopliae are promising alternatives of entomopathogenic fungi as possible tools in the management of biological control of Diatraea saccharalis (Rodrigues et al, 2016) and Agrotis Ipisilon due to toxins that these fungi release in the Insects (Gabarty et al, 2014).…”

The areas of maize production harbor a high number of insect species, some of which are considered pests that cause damage to the crop. The methods of pest control have been a cause of concern for the society since the use of chemicals and the environmental problems arising from this practice indicate the need to search for alternatives to control. In this sense, it is necessary to seek an agricultural production system that contemplates environmental sustainability and promotes biodiversity in the Agrosystem, among which the use of biological agents is highlighted. The objective of this research was to update through a bibliographic review the advances in the literature on biological control of maize crop pests. For the development of this article, we used the method of approach the analytical and as procedural method the monographic, through bibliographic research, using specialized doctrines, appropriate to the object of the study and legislations. Because of the observed aspects, it is possible to conclude that the group of natural enemies that act as biological control agents is formed by parasitoids, predators and entomopathogenic microorganisms. The rationalization of the use of chemicals should be associated with the use of biodefensives in integrated pest management. Advances in the legislation of biological products in Brazil are fundamental to give speed to the registration of new alternatives of biological control, aimed at the safety of the environment, human health and that are generated without the exploratory use of biodiversity.

Beauveria bassiana is one of the entomopathogenic fungi to control various kinds of insect pests. Virulence of B. bassiana against insects could be affected by ultraviolet (UV) light. The study was aimed to determine the effect of different times of UV light exposure to B. bassiana against Spodoptera litura. The study was arranged in a Completely Randomized Design (CRD) with six different times of UV light exposure (control, 0, 15, 30, 45, 60 minutes) in four replications, respectively. Those B. bassiana were inoculated on the second instar of larvae of S. litura. The parameters observed were colony growth of B. bassiana, conidial germination, larval mortality, percentage of pupae, and adults formed. The data were analyzed by analysis of variance and LSD test at the 5% significance level. The results showed that exposure of B. bassiana to UV light reduced its germination but not inhibit the growth of B. bassiana. The exposure for 45 minutes and 60 minutes increased the virulence of B. bassiana that indicated by an increase of S. litura mortality (15.0-62.5%) and shorter LT50 (6.29-10.92).

“…In spite of this microbial agent play an important role in the control of H. hampei, its efficiency is conditioned to environmental factors, like ultraviolet radiation, temperature, moisture, altitude, product concentration, correct application, among others (Vega et al, 2015;Aristizábal et al, 2016). The ultraviolet radiation and high temperatures reduce field conidia viability, because this affects its metabolism, changing enzyme production processes, toxins, spore germination, germ tube development, penetration, colonization and reproduction (Alves & Lecuona, 1998;Rodrigues et al, 2016). Besides that, the fungus loses its ability to infect when subjected to direct sunlight for three hours (Alves & Lecuona, 1998;Rodrigues et al, 2016).…”

The coffee berry borer, Hypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae: Scolytinae) presents a cryptic life cycle, which occurs all within the fruit, which makes its control a difficult task. For this reason, one of the methods that has stood out is the biological control through the entomopathogenic fungus Beauveria bassiana (Balsamo) (Hypocreales: Cordycipitaceae). However, the efficiency of this fungus is conditioned to environmental factors, such as ultraviolet radiation, temperature, humidity, concentration, correct application, among others. Therefore, the objective of the present study is to evaluate the mortality of coffee berry borer, pre and post application of the entomopathogenic fungus Beauveria bassiana associated with emulsifiers under field conditions. The experiments were conducted in three farms in different locations. The fungus isolate used was the PL63, and emulsifiers (Gum arabic and X1) evaluated were gum arabic and X1 (product subject to patent). Two modes of application were performed: pre and post the coffee berry borer release. In the pre-application, the fungi were mixed in with the emulsifiers and the pure, and after thirty minutes, the coffee berry borer was released. In the post-application, it released the insects, and after 24 hours, the fungus was applied with the emulsifiers and pure. All treatments tested showed coffee berry borer mortality; the emulsifying agents (Gum and X1) in admixture with the fungus B. bassiana, did not increase the mortality of coffee berry borer; the application of the fungus B. bassiana before the entry of the drill into the coffee fruit, resulted in higher mortality.
