Hungrier larvae of both species had more encounters and incidences of cannibalism with a shorter latency period than their satiated counterparts.

The experiments were accomplished in a randomized complete block design with treatments of intercropping onion (O) and safflower (S) in three patterns of row alternation: 4O:2S, 4O:4S, and 4O:8S along with the sole cropping of onion and safflower.

Besides, the leaf damage index per plant decreased in the intercropping systems compared to the onion sole cropping, reaching the lowest value in 4O:4S and 4O:8S in two years. The total abundance of onion plant- or ground-dwelling predators was higher in intercrops than in the sole crop. Further, higher Shannon diversity indices for onion plant-dwelling predators (<i>H</i>′ ≥ 1.73) and ground-dwelling predators (<i>H</i>′ ≥ 1.30) were recorded in intercrops, especially 4O:4S and 4O:8S.

These plantations have been progressively invaded by Australian insects, some of which have become pests, threatening the plantation productivity, and modifying ecological networks of trophic interactions. In this study we addressed whether ants could recognize and exploit the food sources offered by the introduced psyllids (Sternorrhyncha) associated with eucalypts. We hypothesised that ant-psyllids interaction will be more likely with exotic ant species than with the native ones, because of their higher abundance in anthropogenic habitats. For this reason, we also expected differences in ant biodiversity between plantations located near and far from human settlements. We studied the presence of ants on eucalypt trees, the ant diversity found on the ground in eight eucalypt plantations, and analysed in the laboratory the interactions between psyllids and three ant species, two native and one invasive. In the field, we found native ant species over psyllid clusters in eucalypts, as well as a higher use of eucalypt resources and colonization by specialist species in plantations distant from human settlements. However, we did not find differences in ant diversity between plantations near and distant from human settlements. Despite their absence in the field, during the laboratory experiment, exotic ant workers were more attracted to psyllids than the native ants. Our results point to invasive species as potential users of this resource. We discuss potential factors involved in the ant-psyllid interactions and suggest that introduced eucalypt plantations are low-quality habitats for ants.</p></div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"18 2","pages":"287 - 297"},"PeriodicalIF":1.2,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139686134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
