SummaryThis study was conducted between 2012 and 2013 years on sour orange in Aydın city centre (Muğla, Atatürk and Batı Gazi Boulevard). The aim of the study was determine population density and natural enemies of A.floccosus. Samplings were made periodically every 15 days. As a result; It was determined that A. flococcus produced three generations a year and its populations peaked between June and July. It was observed that A. flococcus owerwintered in nymph and pupae stages on sour orange trees in Aydın. Cales noacki Howard (Hymenoptera: Aphelinidae) was found as natural enemy on A. floccosus. Parasitization was the highest in September and parasitization rate has reached to 27,2% in both years. In the suitable weather conditions and absence of natural enemies, it is considered that A. flococcus may reach to high population. We conclude that A. floccosus can be controlled by its parasitoid if it can be protected during the sprayings for mosquito control in the city. A. floccosus 'un yılda üç döl verdiği ve en yüksek popülasyon düzeyine haziran-temmuz ayında ulaştığı saptanmıştır. Zararlının kışı Aydın koşullarında turunç ağaçlarında nimf ve pupa döneminde geçirdiği gözlenmiştir. A. flococcus 'un doğal düşmanı olarak Cales noacki Howard (Hymenoptera: Aphelinidae) belirlenmiştir. Her iki yılda da C. noacki ile parazitlenme oranının en yüksek olduğu zamanın eylül ayı olduğu ve bu oranın %27.2'ye kadar yükseldiği görülmüştür. Uygun iklim şartları ve doğal düşmanların yokluğunda, A. floccosus' un yüksek popülasyon oluşturabileceği düşünülmektedir. Bu nedenle, özellikle şehir merkezinde yapılan sivrisinek ilaçlamalarında gerekli önlemlerin alınarak doğal düşman varlığının korunması gerektiği sonucuna varılmıştır.
In this study, which was carried out in Aydın Province of Türkiye in 2019, predatory species belonging to the Coccinellidae family on mealybug infested plants in agricultural and non-agricultural areas, are reported and discussed. Ten predator species belonging to the Coccinellidae family were identified from 22 host plant species infested with mealybugs. These predator species are promising candidates for mass rearing for biological control purposes in the future.
As a result of surveys conducted in Aydın Province (Turkey), 19 parasitoids belonging to the family Encyrtidae were found on pseudococcids. Four species are newly recorded from Turkey: Anusia tornike Japoshvili, Coccidoxenoides perminutus Girault, Homalotylus quaylei (Timberlake), and Prochiloneurus aegyptiacus (Mercet). One new species, Leptomastix baspinari Japoshvili sp. n., is described and illustrated. This species was recorded parasitizing six different mealybugs on ten different plant species, including weeds, ornamentals, and crops. Based on its host range, this parasitoid may be a very promising biocontrol agent against many mealybug species.
Mealybugs (Hemiptera: Coccomorpha: Pseudococcidae) include economically important insect pests worldwide. Pseudococcus Westwood is the second biggest genus in Pseudococcidae, with several pest species. Pseudococcus adult females were collected and identified from wild and cultivated plants in Turkey. Molecular and morphological characters were analyzed to investigate the relationship among species. It was recognized that Pseudoccoccus species are shown in three distinctive groups concerning to both morphological and molecular aspects.
Mealybugs (Hemiptera: Coccomorpha: Pseudococcidae) were collected from Aydın province, Turkey between 2019 and 2021 to document the species found in agricultural and non-agricultural areas. Thirty-five species belonging to 16 genera were collected from more than 150 host plants. Six of the species are new country records for Turkey: Allotrionymus multipori Kawai, 1973; Kiritshenkella sacchari (Green, 1900); Phenacoccus parietaricola Goux, 1938; Phenacoccus peruvianus Granara de Willink, 2007; Phenacoccus schmelevi Bazarov, 1980 and Spilococcus flavus (Borchsenius, 1949). Seyneria neohordei (Marotta, 1992) is returned to its original genus assignment, as Phenacoccus neohordei Marotta comb. rev.
