Abstract

Pitaya, Hylocereus spp. (Caryophyllales: Cactaceae) has been one of the new species cultivated in Türkiye for recent years. There are many limiting factors, including pests, diseases and weeds, to decrease the yield and fruit quality in pitaya (dragon fruit) areas in Türkiye. In addition, the pests of pitaya is not fully studied therefore this study has been conducted to determine mealybug species in pitaya greenhouses in Türkiye. The present study was aimed to determine mealybug species and its natural enemies (parasitoids, and predator insects) in pitaya greenhouses in Adana, Mersin, and Antalya between 2021 and 2022. According to results of this study, 2 different mealybug species was determined; Phenacoccus solenopsis Tinsley 1898, Phenacoccus madeirensis Green, 1923 (Hemiptera: Pseudococcidae) in pitaya greenhouses. Moreover 1 parasitoid (Aenasius arizonensis Girault (Hymenoptera: Encyrtidae), and 2 different predatory insects from 2 different order and 2 different families (Chrysoperla carnea Stephens (Neuroptera: Chrysopidae), Nephus includens Kirsch (Coleoptera: Coccinellidae)) were detected within this study. As can be seen above results, these two invasive mealybug species have wide spectrum host plants and may cause economically important damages on pitaya, if natural enemies cannot work successfully or control strategies do not applied properly in pitaya greenhouses.

确定地中海地区番木瓜温室中的蚧壳虫种类和天敌

火龙果（Hylocereus spp.）（Caryophyllales: Cactaceae）是土耳其近年来栽培的新品种之一。蒂尔基耶火龙果种植区的产量和果实质量受到许多限制因素的影响，其中包括害虫、疾病和杂草。此外，对火龙果害虫的研究并不充分，因此本研究旨在确定土耳其火龙果温室中的蚧壳虫种类。本研究旨在确定 2021 年至 2022 年期间阿达纳、梅尔辛和安塔利亚番木瓜温室中的蚧壳虫种类及其天敌（寄生虫和捕食昆虫）。研究结果表明，在番木瓜温室中发现了 2 种不同的蚧壳虫，分别是 Phenacoccus solenopsis Tinsley 1898 和 Phenacoccus madeirensis Green, 1923（半翅目：假蝉科）。此外，本研究还发现了 1 种寄生虫（Aenasius arizonensis Girault，膜翅目：Encyrtidae）和 2 种不同目、2 个不同科的捕食性昆虫（Chrysoperla carnea Stephens，神经翅目：Chrysopidae）、Nephus includens Kirsch，鞘翅目：Coccinellidae）。从以上结果可以看出，这两种入侵蚧壳虫的寄主植物范围很广，如果天敌不能成功发挥作用，或在番木瓜温室中没有适当采用控制策略，可能会对番木瓜造成重要的经济损失。
