“…isolate ESALQ-1448 was tested against Aphids and identified that the LT 50 rate was over 10 days. In another study, four different isolates of S. lamellicola were used against adult mosquitos and mortality rates were between 53.2% and 63.9% at the end of day 14 (Ishii et al, 2015). Iskender et al (2012) found that three isolates of B. bassiana tested on H. cunea larvae caused mortality between 90±5.77% and 96.6±3.33%.…”

Article history:Received date: 20.04.2017 Accepted date: 15.06.2017 Fall webworm (Hyphantria cunea Durry, Lepidoptera: Arctidae) is an important pest infecting about 600 hosts. It is harmful especially in hazelnut orchards in the Black Sea Region and is becoming epidemic occasionally. It may cause damage in mulberry, cherry, apple, poplar, and willow beside hazelnut in the region. Due to having a polyphagous feeding behavior and a high reproduction power; fall webworm can spread rapidly and make difficult to manage. In the region, currently, mostly chemical control is applied against this pest. Due to adverse effects of the chemical control to the environment and to living organisms, it is inevitable to develop other alternative control methods for this pest. In this study, the effects of some entomopathogenic fungi isolates obtained from Palomena prasina which is another pest in hazelnut production areas, on H. cunea in laboratory conditions. Overall, 1x10 8 conidia mL -1 of concentration obtained from 2 isolates of Simplicillium lamellicola (TR-01 and TR-02) and 4 isolates of Lecanicillium muscarium (TR-04, TR-05, TR-07 and TR-08) was used against 3 rd period larva of the H. cunea. The experiment was conducted with four replications, 10 larvae individuals in each. Mortality of H. cunea were reported daily, over 12 days. At the end of 12 th day, among the isolates of entomopathogenic fungi, the TR-05 isolate of the L. muscarium ranked the highest mortality by 93.9% rate. Effect of the other isolates of L. muscarium varied between 72.7% and 90.9%. The TR-01 isolate of the S. lamellicola showed effect of 57.6%, and the TR-02 isolate showed effect of 78.8% mortality. Effects of all the isolates used in the study were differed from the control (P<0.05). Based on LT 50 and LT 90 values, the most effective isolate was identified as TR-04 (5.64/day and 9.38/day, respectively). It can be concluded that, the isolates of L. muscarium was found quite effective and it could be a promising agent for controlling this pest in the field in the future.

“…Numerous orders of arthropods that are vulnerable to the use of Paecilomyces spp. ( Table 3 ), including hemiptera, have been described, such as aleurodids [ 246 ], aphids [ 238 ], thysanoptera [ 242 ], diptera [ 247 ], lepidoptera [ 73 ], hymenoptera [ 248 ] and coleoptera [ 235 ].…”

Incorporating beneficial microorganisms in crop production is the most promising strategy for maintaining agricultural productivity and reducing the use of inorganic fertilizers, herbicides, and pesticides. Numerous microorganisms have been described in the literature as biological control agents for pests and diseases, although some have not yet been commercialised due to their lack of viability or efficacy in different crops. Paecilomyces is a cosmopolitan fungus that is mainly known for its nematophagous capacity, but it has also been reported as an insect parasite and biological control agent of several fungi and phytopathogenic bacteria through different mechanisms of action. In addition, species of this genus have recently been described as biostimulants of plant growth and crop yield. This review includes all the information on the genus Paecilomyces as a biological control agent for pests and diseases. Its growth rate and high spore production rate in numerous substrates ensures the production of viable, affordable, and efficient commercial formulations for agricultural use.

“…En la Tabla 6, se observa que el porcentaje promedio de mortalidad de larvas de A. aegypti a la aplicación de B. bassiana se da a partir de los 4 días y está en relación directa al tiempo y a la concentración, pues a mayor tiempo de exposición a las concentraciones aumenta la mortalidad de larvas de A. aegypti, resultados similares a los obtenidos por Miranpuri y Khachatourians, (1991), quienes encontraron una gran efectividad de B. bassiana, contra este insecto. Esta efectividad se debe a los conidios de B. bassiana pues estos son retenidos por contacto en la superficie de la cutícula hasta formar los túbulos germinales que facilitan la diseminación del hongo a través del hemocele (Deshpande, 1999), alterando sus funciones fisiológicas, así como, el deterioro de sus órganos hasta producirle parálisis y finalmente la muerte en un lapso entre 4 y 12 días (Ishii et al, 2015), corroborando los resultados obtenidos, encontrándose dentro de los límites establecidos del tiempo de mortalidad.…”

En el presente trabajo se evaluó la actividad larvicida de Bacillus thuringiensis H-14 var. israelensis y Beauveria bassiana sobre larvas del III estadio de Aedes aegypti, bajo condiciones de laboratorio, además se determinó la dosis letal media (DL50) y máxima (DL90). Se realizaron los bioensayos con doce grupos experimentales y dos grupos control, con tres repeticiones, utilizando 25 larvas del III estadio de A. aegypti en 100 mL de agua destilada por cada unidad experimental. Se utilizaron seis grupos experimentales con B. thuringiensis H-14 var. israelensis, a las concentraciones de 670; 1683; 4247; 10619; 26673; 67000 esp/mL y un grupo control; obteniéndose una mortalidad del 50% a las 8 horas y del 100% a las 24 horas. Con B. bassiana se utilizaron seis grupos experimentales a las concentraciones de 4x10 8 ; 1x10 9 ; 2,5x10 9 ; 6,3x10 9 ; 1,6x10 10 ; 4x10 10 conidios/mL y un grupo control; obteniéndose una mortalidad del 50% a los 7 días y del 100% a los 9 días. Mediante la dosis letal media (LD50) y máxima (DL90) se demostró que tanto B. thuringiensis H-14 var. israelensis como B. bassiana presentan mayor mortalidad en relación directa a la concentración e inversamente al tiempo. Se concluye que B. thuringiensis H-14 var. israelensis y B. bassiana a las diferentes concentraciones utilizadas en los bioensayos, presentó una alta actividad larvicida en A. aegypti bajo condiciones de laboratorio.
