This study was carried out to evaluate two biological methods for the control of Ectomyelois ceratoniae (Lepidoptera: Pyralidae) which is considered to be the most important pest species in Tunisia. Mass trapping through 14 traps (water and delta) baited with sex pheromone, and Trichogramma cacoeciae releases with two doses: 25,000 Trichogramma (T)/ha (D1) and 50,000 T/ha (D2) were tested separately. Field trials were conducted during 2016 in oases cultivated by date palm trees and pomegranates. In this experiment the infestation rates for delta traps, water traps and control were 17.6, 32.9 and 87.3%, respectively. Therefore, mass trapping with 14 delta traps was the most effective on pomegranate fruits. After inundative releases of T. cacoeciae (D1: 25,000 and D2: 50,000 T/ha), the results revealed an impact of this parasitoid in inhibiting carob moth eggs hatching, and a significant reduction of the infestation rate of pomegranate fruits between 19.1 and 22.7% for both doses compared to control plot with 87.3%. However, these trials (mass trapping and Trichogramma releases) applied on date palm trees were not sufficient to limit economic losses.

进行了这项研究，以评估两种控制方法，这些方法可用于控制ceratoniae ceratoniae（鳞翅目：Pyralidae），这是突尼斯最重要的害虫。通过用性信息素诱饵的14个诱集装置（水和三角洲）进行诱捕，并分别测试了两种剂量的马尾形毛线虫的释放：25,000个赤眼线虫（T）/ ha（D1）和50,000 T / ha（D2）。2016年期间对枣椰树和石榴种植的绿洲进行了田间试验。在该实验中，三角洲陷阱，集水区和控制区的感染率分别为17.6％， 32.9％和87.3％，分别。因此，用14个三角诱集器诱集对石榴果实最有效。在大量释放T. cacoeciae（D1：25,000和D2：50,000 T / ha）之后，结果表明这种寄生虫对抑制角豆蛾卵的孵化有影响，并且在19.1和22.7之间显着降低了石榴果实的侵染率。两种剂量的百分数为％，而对照组为87.3％。但是，对枣椰树进行的这些试验（诱捕和赤眼蜂释放）不足以限制经济损失。
