20.500.12556/RUL-184446 Exploring the biodiversity of aphid communities and their natural enemies in citrus orchards in the north-west of Algeria Raziskovanje biotske raznovrstnosti skupnosti listnih uši in njihovih naravnih sovražnikov v nasadih citrusov na severozahodu Alžirije Citrus production in Algeria is threatened by aphid infestations, which damage plants directly and transmit Citrus Tristeza Virus (CTV). Although chemical pesticides remain the dominant control approach, their environmental and health impacts underscore the urgency of developing sustainable pest management alternatives. To support sustainable pest management, this study assessed aphid communities and their natural enemies in citrus orchards of northwestern Algeria (Chlef) from September 2023 to August 2024. A total of 8347 aphids belonging to six species were recorded, dominated by Aphis spiraecola and Aphis gossypii. In parallel, 1956 natural enemies were identified, including 15 predator species and four parasitoid species. Predators represented 60.1 % of the community, mainly hoverflies, whereas parasitoids (39.9 %) were dominated by Lysiphlebus testaceipes. Aphid populations peaked during spring and early summer under favorable climatic conditions. Surveys of surrounding vegetation showed that aphids persist on nearby crops and wild plants, highlighting the role of the agroecosystem in maintaining populations. Overall, the results confirm the important potential of predators and parasitoids in the biological control of citrus aphids. citrus aphids biological control parasitoids predators agroecosystem Algeria citrusi listne uši biološki nadzor parazitoidi plenilci agroekosistem Alžirija true false true Angleški jezik Slovenski jezik Članek v reviji 2026-07-07 14:48:53 2026-07-07 14:48:56 2026-07-08 04:12:22 0000-00-00 00:00:00 2026 0 0 11 str. no. 2 Vol. 122 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63 1854-1941 10.14720/aas.2026.122.2.23095 283959299 BADANI+et+al.+(J).pdf BADANI+et+al.+(J).pdf 1 B340634BCD14C9478B1B3418F8DD6309 f542bb0a70c74318a00ce3030e28ad406690d2f87d8467cc9007f7f493ff7fb4 41648b13-7a02-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=237272 https://journals.uni-lj.si/aas/article/view/23095 1 1bbcc7cd-7a02-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=237271 Biotehniška fakulteta 0 0 0
