“…The treatments Metarhizium anisopliae (Metarril) and Actara 750SG showed greater potential for reducing the number of leafhopper nymphs in sugarcane (Figure 3B). Studies by Barbosa et al (2015), verified efficiency in controlling leafhopper nymphs using Metarhizium anisopliae.…”

This work aimed to evaluate the agronomic effectiveness and practicality of microbiological insecticides in cotton, sugar cane, citrus, beans, tomatoes, coffee, wheat, soybeans and maize crops based on bacteria of the genus Pseudomonas fluorescens Pseudomonas chlororaphis and Bacillus thuringiensis, in the control of insect pests. Experiments were carried out to evaluate biological insecticides in each crop individually. Experiments were carried out in each culture in various environments in the states of MT, MS, SP, MG and PR in Brazil. A randomized block design with four replications was used in all the experiments. Agronomic traits, insect pest incidence and insecticide efficiency were evaluated for each of the crops. A heat map was made to understand the efficiency of insecticides in controlling insect pests in each crop. The linear correlation coefficients between the pairs of characters evaluated were calculated. The use of bacteria of the genus Pseudomonas fluorescens, Pseudomonas chlororaphis and Bacillus thuringiensis to control insect pests is a promising alternative for use alone or in combination with pesticides. The use of azadirachtin is effective for controlling mites in cotton, Diaphorina citri in citrus and moth in tomato.

Termites of the Nasutitermes genus are considered one of the main urban and agroforestry pests in Brazil, where the main method of control is the application of pesticides. The uso of entomopathogenic fungi to reduce the population of this plague in the environment could be use as an alternative. The goal of this study was to evaluate the virulence of isolates native Amazonian fungi belonging to the Tolypocladium endophyticum, Metarhizium anisopliae and Metarhizium marquandii species for the control of Nasutitermes sp. The strains of T. endophyticum (4.439), M. anisopliae (4.443) and M. marquandii (4.472) with their respective isolation codes, were evaluated using suspensions at concentrations of 105, 106, 107 and 108 conidia/mL against the termites. The fungi were characterized to species level by molecular analysis. The greatest virulence was registered with T. endophyticum (4.439), with a mortality of 100 % on the 4th day of treatment for all analyzed concentrations. The M. anisopliae strain (4.443) proved to be efficient, causing a mortality of 100 % on the 7th and 6th days at dilutions of 107 and 108 conidia/mL, respectively. Rates lower than 100 % were registered with M. marquandii (4.472). Therefore, the three fungal strains showed virulence against the termites Nasutitermes sp. In this study, the fungi Tolypocladium endophyticum and Metarhizium marquandii are reported for the first time for the biological control of pests, indicating the potential of native Amazonian fungi for the biological control of thermites Nasutitermes sp.

“…The chemical control of this pest is widely used in sugar cane, through the use of Thiamethoxam, Aldicarb, Carbofuran and Imidalcloprid, significantly reducing infestations of the pest in the sugarcane crop (Barbosa et al, 2015). However, chemical control has some disadvantages compared to biological control such as the possibility of resurgence of the pest, generation of resistant insects, human and environmental contamination, which has motivated the search for ecological strategies to control these insects, with isolated of native Metarhizium, due to the fact that in other countries such as Brazil, they have demonstrated that the mycoinsecticides based on Metarhizium anisopliae have been effective in the control of this pest (Rezende et al, 2015).…”

The efficacy of four native isolations of Metarhizium anisopliae in the control of Mahanarva andigena nymphs in greenhouse and field was evaluated. In both conditions, the treatments were: four native isolations: T1: MT-51 (01), T2: P-50 (01), T3: T-63 (01) and T4: F55 (01); a commercial strain T5: Metazeb and T6 control treatment. In a greenhouse, 30 days old sugar cane seedlings were used, each one was infested with 10 fourth instar nymphs and subsequently sprinkled with 15 mL of a suspension of 1x108 conidia/mL-1 for each isolation, the commercial strain at a dose of 2x1012 conidia/ha-1 (300 g of commercial product/ha-1) and the control treatment (sterile distilled water + agral 90). In greenhouse mortality was recorded for seven days and the corrected and confirmed mortality was determined. In the field, the treatments were sprayed at the same concentrations. The effectiveness of the treatments was determined at 7 and 14 days after the application, with the Henderson-Tilton formula. In the greenhouse treatments, T1, T2 and T3 caused high percentages of confirmed mortality, with values of 71.11, 67.5 and 54.45%, respectively, higher than the commercial strain, and in the field at 14 days, the application of treatments T1 and T2, reached an efficiency of 73.08 and 69.68%, higher than other treatments. These results demonstrate that the T1 isolations: MT-51 (01) and T2: P-50 (01) in greenhouse and field induced a high mortality of M. andigena nymphs, so they are the most promising for use as control biological agents of this insect pest in the cultivation of sugar cane.
