Survey of the Ficus whitefly, Singhiella simplex (Hemiptera: Aleyrodidae), and its natural enemies in the Western Mediterranean Region of Turkey
Abstract
In this study, the distribution of the Ficus whitefly, Singhiella simplex (Singh) (Hemiptera: Aleyrodidae), and its natural enemies in the Western Mediterranean Region of Turkey were investigated. For this purpose, the sampling was made from trees of Ficus spp. during Aug, Sep, and Oct when the pest population was at its peak in the various districts within the Antalya province in 2018 and 2019. In addition, the rate of natural parasitism in the sampling periods also was determined. To determine the dispersal and parasitoids of S. simplex, at least 100 branches were collected from Ficus trees in each district, the Ficus trees were checked visually for the determination of the predators. The results showed that Ficus whitefly is dispersed in all the districts within the Antalya province. Encarsia protransvena Viggiani (Hymenoptera: Aphelinidae) has been identified as the parasitoid of the Ficus whitefly in Antalya and its districts, wereas the highest natural parasitism rate was found to be 32.88% and 21.66% in Oct 2018 and 2019, respectively, across the sampling mo. Chrysoperla mutata (McLachlan) (Neuroptera: Chrysopidae), Semidalis aleyrodiformis (Stephens) (Neuroptera: Coniopterygidae), Conwentzia psociformis (Curtis) (Neuroptera: Coniopterygidae), Conwentzia sp. (Neuroptera: Coniopterygidae), Oenopia conglobata (L.) (Coleoptera: Coccinellidae), and Serangium parcesetosum Sicard (Coleoptera: Coccinellidae) species were determined as the predators. The results obtained in the study may contribute to the control of S. simplex by using its natural enemies.
Resumen
En este estudio, se investigó la distribución de la mosca blanca del ficus, Singhiella simplex (Singh) (Hemiptera: Aleyrodidae), y sus enemigos naturales en la región mediterránea occidental de Turquía. Para tal efecto, el muestreo se realizó a partir de árboles de Ficus spp. durante agosto, septiembre y octubre, cuando la población de plagas alcanzó su punto máximo en los diversos distritos de la provincia de Antalya en el 2018 y 2019. Además, también se determinó la tasa de parasitismo natural en los períodos de muestreo. Para determinar la dispersión y parasitoides de S. simplex se recolectaron al menos 100 ramas de árboles de Ficus en cada distrito, los árboles de Ficus fueron revisados visualmente para la determinación de los depredadores. Los resultados mostraron que la mosca blanca del ficus está dispersa en todos los distritos dentro de la provincia de Antalya. Encarsia protransvena Viggiani (Hymenoptera: Aphelinidae) ha sido identificada como el parasitoide de la mosca blanca del ficus en Antalya y sus distritos, donde se encontró que la tasa de parasitismo natural más alta del 32,88% y el 21,66% en octubre de 2018 y 2019, respectivamente. Se determinó Chrysoperla mutata (McLachlan) (Neuroptera: Chrysopidae), Semidalis aleyrodiformis (Stephens) (Neuroptera: Coniopterygidae), Conwentzia psociformis (Curtis) (Neuroptera: Coniopterygidae), Conwentzia sp., Oenopia conglobata (L.) (Coleoptera: Coccinellidae), y Serangium parcesetosum Sicard (Coleoptera: Coccinellidae) como depredadores. Los resultados obtenidos en el estudio pueden contribuir al control de S. simplex mediante el uso de sus enemigos naturales.
