The ladybird <i>Eriopis connexa</i> (Germar, 1824) is a generalist predator known for its voracity and ability to exploit aphid populations across diverse habitats. This study aimed to evaluate the foraging behaviour and prey preference of <i>E. connexa</i> when exposed to two aphid species, <i>Myzus persicae</i> (Sulzer, 1776) and <i>Aphis gossypii</i> Glover, 1877, under varying ecological contexts. We conducted three independent experiments to assess: (i) preference across developmental stages (2nd vs. 4th instars); (ii) functional response to increasing prey density; and (iii) prey choice in varying species proportions. Results indicate that <i>E. connexa</i> lacks an intrinsic preference for either aphid species. Instead, its predation behaviour is significantly influenced by prey characteristics such as instar stage and relative abundance. The predator tended to consume smaller instars and more abundant prey first, suggesting decisions based on prey profitability.

Infestations can reduce fruit production and quality due to sooty mould development. Accurate species-level identification of mealybugs is valuable for effective agricultural pest management and in some cases may be of phytosanitary relevance. Traditional morphological identification is challenging. Slide mounted adult female specimens are usually required for accurate morphological identification, a process that is time consuming and requires specialist skills. Molecular diagnostics targeting mitochondrial genes, particularly the cytochrome c oxidase subunit I (<i>COI</i>), have become valuable rapid tools for reliable species discrimination in most insect groups. The use of molecular techniques in combination with morphological assessments provides stronger support for accurate species identification. This study reports the first validated mitochondrial genome of <i>P. citri</i>, an important citrus pest, alongside partial mitochondrial sequences for the six other mealybug species previously reported on citrus and two other species that are not associated with citrus in South Africa. Using high-throughput and Sanger sequencing combined with manual curation, a high-confidence <i>P. citri</i> mitogenome was assembled while draft mitogenomes were generated for the other species. Two complementary molecular assays were developed and validated. These consisted of a set of multiplex PCRs and restriction enzyme digest assays that enable rapid, same-day differentiation of the nine mealybug species. The multiplex PCR assays provide sensitive and specific detection, while the restriction digest assays act as a confirmatory tool and fail-safe mechanism, allowing early identification of discrepancies. In one of the species, <i>Nipaecoccus viridis</i>, greater genetic diversity was uncovered, suggesting cryptic speciation.

Pollination success depends not only on the presence of flower visitors but also on their behaviour and traits. Although Chile is among the world's leading cherry producers, information on the diversity and pollination roles of insect visitors in its orchards remains scarce. In this study, we used video monitoring to assess the foraging behaviour of floral visitors in 16 conventional orchards in central Chile. In 2023, we recorded 3012 insect visits. Bees comprised 65% of visits, with honey bees (<i>Apis mellifera</i>) alone accounting for 64% and fewer than 1% for wild bees. Besides, 33% of the visits were attributed to flies—mainly <i>Dilophus</i> sp. (Bibionidae) and several syrphid species—and 2% to beetles. Bees spent the shortest time per flower, exhibited greater inter-floral movement and contacted the stigma most frequently, behaviours associated with high pollination potential. In contrast, flies and beetles typically remained longer on flowers, moved little between them and often consumed floral resources without making contact with the stigma. These behavioural patterns suggest that hymenopterans are the most effective pollinators in these systems. Nevertheless, the high abundance of flies in the orchards may partly compensate for their limited pollination efficiency. Additionally, we found a significant positive relationship between body size and the likelihood of stigma contact, highlighting a key morphological trait associated with pollination effectiveness. The overall low diversity and small size of floral visitors in these conventional cherry orchards may explain why few of the species present have the potential to be effective pollinators. Promoting practices that enhance bee floral visitor diversity could increase the presence of alternative pollinators, reduce reliance on managed honeybees and contribute to more stable cherry yields.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"150 4","pages":"475-486"},"PeriodicalIF":2.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683993","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}
