Evaluation of Chinchorro Biological Control (Leptoglossus zonatus), using two entomopathogenic fungi

It is urgently necessary to replace synthetic pesticides with alternatives that help the recovery, optimization and conservation of the delicate balance of ecosystems. Numerous works and experiences at national and international level confirm the effectiveness of biological control. GENERAL OBJECTIVE: Look for a new Chinchorro (Leptoglossus zonatus) control alternative based on biological methods. Specific objectives: - Evaluate Chinchorro's biological control in relation to chemical control and absolute witness. - Compare the results of the biological control of the fungi Beauveria Bassiana and Metarhizium anisoplye. - Determine the most active dose of the fungi Beauveria Bassiana and Metarhizium anisoplye in the biological control of Chinchorro. - Evaluate the costs of biological and chemical control. Hypothesis: - Chinchorro's biological control is as or more efficient than chemical control. - The B. Bassiana fungus controls the Chinchorro better than the M. Anisoplye fungus. - The dose of 4 g/l is better than the dose of 2 g/l in the biological control of the Chinchorro. - Biological control is cheaper than chemical control. Research Methodology Two entomopathogenic fungi will be tested (Beauveria Bassiana and Metarhizium anisoplye) in dose of 0.0, 2.0 and 4.0 grams per liter of water, a chemical insecticide and a witness in a design of complete blocks with six treatments and three repetitions. The number of chinchorros per treatment will be 10 and two experiments will be carried out. The first with adult states and the second experiment with nymph states of the insect. In total, 360 chinchorros will be used. As a chinchorro host plant, the cheamico (Stramonium) will be used that will be sown in four -liter plastic pots of soil capacity.
