20.500.12556/RUL-175537 Limiting onion fly (Delia antiqua) and onion thrips (Thrips tabaci) damage to onions by combined use of environmentally acceptable control methods fact or fantasy? In a two-year study (2023–2024), field experiments were conducted at a location where onion fly (Delia antiqua [Meigen]) and onion thrips (Thrips tabaci Lindeman) are permanent pests. The objective of the study was to investigate independent and combined application (synergistic effect) of environmentally acceptable methods (biological and biotechnical control methods) of controlling these pests on onions. Seven treatments were tested, including a positive control (chemical control) and a negative control (untreated plots), as well as various combinations of environmentally friendly approaches, such as entomopathogenic fungi and nematodes, white clover intercropping, and colored sticky boards with lures. The onion fly caused greater damage and subsequent bulb loss than the onion thrips in both years, despite white clover (as independent application) as an intercrop, and the combined application of white clover and entomopathogens proved to be most effective against thrips and fly damage, ultimately resulting in a suboptimal onion yield of less than 7 tons per hectare annually. It is evident that environmentally acceptable control methods were experiencing challenges in either reducing the extent of damage caused by both pests or increasing the yield of healthy bulbs. It is unfortunate that, despite observing an increased yield of healthy bulbs in certain treatments, a significant quantity of bulbs was also lost due to onion fly. synergism biological control chemical control entomopathogens sticky boards white clover biotično varstvo sinergizem škodljivci rastlin kemično varstvo entomopatogeni lepljive plošče bela detelja true false false Angleški jezik Slovenski jezik Članek v reviji 2025-11-03 10:42:05 2025-11-03 10:42:13 2025-12-12 03:39:42 0000-00-00 00:00:00 2025 0 0 20 str. iss. 11, art. 1097 Vol. 16 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 632 2075-4450 10.3390/insects16111097 255609347 Insects_(Bohinc__Trdan_2025).pdf Insects_(Bohinc__Trdan_2025).pdf 1 8C87EFA6F92FC4B0E1DF15CFFE70DBE5 4e34014e45386a5145c17250948704a75cbcd1ec95bbfc7e6bcb9eb05c6f1512 5b248de1-b899-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=221176 https://www.mdpi.com/2075-4450/16/11/1097 1 1108f3f3-b899-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=221175 Biotehniška fakulteta 0 0 0
