20.500.12556/RUL-175199 Efectiveness of four release doses of two parasitoids species, Trichogramma (Hymenoptera: Trichogrammatidae) in some biological aspects of the lesser date moth Batrachedra amydraula Meyricke, 1916 (Cosmopteridae Batrachedridae) on date palm trees in Basrah/Iraq Učinkovitost štirih velikosti izpustitve parazitoidnih vrst iz rodu, Trichogramma (Hymenoptera: Trichogrammatidae) na nekatere biološke parametre manjšega dateljevega molja Batrachedra amydraula Meyricke, 1916 (Cosmopteridae: Batrachedridae) na palmah v Basri, Irak Date palms are infested with various destructive insect pests, which cause major economic losses. One of these pests is the smaller date moth Batrachedra amydraula Meyricke, 1916. The study aimed to examine the effectiveness of two different Trichogramma egg parasitoid (Trichogramma brassicae Bezdenko, 1968 and T. evanescens Westwood, 1833) in the biological control of the lesser date moth B. amydraula. Each parasitoid species was examined at four different release doses (250, 500, 750, and 1000 parasitoid/tree). The findings revealed that all species of Trichogramma had a substantial effect, particularly at high doses, on the high parasitism of B. amydraula eggs, reaching 86.75 % for a dose of 1000 T. evanescens parasitoids/tree, with a significant difference reached 83.49 % at a dose of 1000 T. brassicae parasitoids/tree. The maximum rate of emergence of T. evanescens adults was at a dose of 1000 parasitoids/tree, which was much higher than T. brassicae reached 64.20 %. The response of absolute doses of Trichogramma females to B. amydraula spawning sites was evaluated, and the parasite’s egg sites were determined according to tree height. The best parasitism rate was recorded for both Trichogramma species on trees whose height ranged from 1.5 m-2 m. natural enemies lesser date moth Trichogramma date palm B. amydraula naravni sovražniki mali dateljev molj Trichogramma dateljevec B. amydraula true false true Angleški jezik Slovenski jezik Članek v reviji 2025-10-21 11:22:59 2025-10-21 11:23:05 2025-12-07 03:53:36 0000-00-00 00:00:00 2025 0 0 8 str. no. 3 Vol. 121 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63 1854-1941 10.14720/aas.2025.121.3.21435 254048515 View_of_Effectiveness_of_four_release_doses_of_two_parasitoids_species,_Trichogramma_(Hymenoptera__Trichogrammatidae)_in_some_biological_aspects_of_the_lesser_date_moth_Batrachedra_amydraula_Meyricke_(Cosmopteridae__Batrachedridae)_on_date_palm__.pdf View_of_Effectiveness_of_four_release_doses_of_two_parasitoids_species,_Trichogramma_(Hymenoptera__Trichogrammatidae)_in_some_biological_aspects_of_the_lesser_date_moth_Batrachedra_amydraula_Meyricke_(Cosmopteridae__Batrachedridae)_on_date_palm__.pdf 1 55AB93427072F1130D4C4BE1AB8821C4 1cb18a0bac5bb5b3f9bd6e7a83f9435089e52eaf9915e8759fb526f54201e6c4 67f3d906-ae5f-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220519 https://journals.uni-lj.si/aas/article/view/21435/18912 1 45103dbd-ae5f-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220518 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
