En busca de una alternativa de control del mosquito Culex quinquefasciatus en áreas urbanas se desarrolló el proyecto: “Evaluación de microorganismos biocontroladores sobre el mosquito Culex quinquefasciatus” cuyo objetivo fue evaluar la capacidad biocontroladora de diferentes hongos entomopatógenos sobre larvas del mosquito a nivel de laboratorio. Se evaluaron 16 aislamientos de hongos en diferentes concentraciones. Se constataron diferencias en el porcentaje de mortalidad producido en larvas de Cx. quinquefasciatus dependientes del tipo de aislamiento, de la concentración utilizada y del tiempo de exposición. Los aislamientos que presentaron el nivel de mortalidad más alto pertenecen a la especie Metarhizium anisopliae, seguidos por aislamientos de la especie Beauveria bassiana. El aislamiento que presentó el mayor nivel de mortalidad (100%) en menor tiempo de exposición (24 horas) fue Metarhizium anisopliae 99068 en una concentración de 1x106 e/ml. Por lo tanto este aislamiento es recomendado para su evaluación en campo y desarrollo de un producto comercial.

Con el objetivo de evaluar cuatro cepas del hongo Metarhizium anisopliae (Metschincoff) Sorokin para el control garrapatas del genero Boophilus spp., se seleccionaron dos cepas de garrapatas para su evaluación en su fase adulta sobre terneros parasitados. Se utilizó un diseño completamente al azar, con seis tratamientos y diez repeticiones.En esta fase las cepas PLH y CH 93-3 fueron las que mostraron la mayor efectividad, por lo que fueron evaluadas en garrapatas adultas sobre terneros previamente parasitados; en la prueba in vivo se utilizó un diseño de bloques completamente al azar, cuatro tratamientos (Las dos cepas seleccionadas, un compuesto químico y un placebo a base de agua) y ocho repeticiones. Los resultados mostraron que las dos cepas evaluadas presentaron una efectividad del 50% con respecto al producto químico.

Abstract Background In this study, commercial bioinsecticides including entomopathogenic fungi, Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii, and Spinetoram active ingredient insecticide were evaluated against the tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) larvae. Main body The active ingredients were prepared at the recommended concentrations under laboratory conditions and applied to the 2nd instar larvae of T. absoluta by spraying with a hand sprayer. On the 1st, 3rd, 5th, and 7th days of the application, evaluations were made by counting survived individuals. The findings showed that the highest mortality rates were detected in the case of Spinetoram with 56, 60, 88, and 100% on all counting days of the experiments, respectively. The highest mortality rate among bioinsecticides was recorded for M. anisopliae, with 87% mortality on the 7th day of application. Short conclusion As a result, Spinetoram was found the most effective insecticide when applied to T. absoluta, followed by M. anisopliae.

Abstract Background The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is a noxious pest of cruciferous crops all over the world causing serious economic damage. Management of insect pest generally depends on chemical control; however, due to development of resistance against all types of insecticides, alternative approaches especially utilization of a microbial agent is inevitable. Results Potential of 2 entomopathogenic fungi (EPF), viz., Beauveria bassiana and Metarhizium anisopliae, was evaluated against 2nd and 3rd larval instars of P. xylostella by adopting leaf dip and direct spraying methods under laboratory conditions. Significant mortality rate was achieved by each fungus under adopted methodologies. However, B. bassiana was found to be more effective in both conditions than M. anisopliae. Highest mean corrected mortality (77.80%) was recorded, when spores of B. bassiana were sprayed on the 2nd instar larvae (LC50=1.78×104/ml) after the 6th day of treatment. Similarly, incase of M. anisopliae LC50 for the 2nd instar at the same methodology was 2.78×104/ml with a mortality percentage of 70.0%. Offspring sex ratio was non-significantly related to treatment concentration and methodology, except for the control. Conclusion Beauveria bassiana and M. anisopliae had potential to suppress P. xylostella infestations when applied appropriately. Present findings suggested that B. bassiana and M. anisopliae when sprayed on immatures of host insect had more effect as compared to leaf dip procedure. Furthermore, no significant effect of concentrations was observed on sex ratio.
