Few studies have evaluated the effectiveness of alternative attractants in the subtropical region worldwide, where environmental conditions and resource availability differ markedly. We tested the effectiveness of two bait types, fermented banana with sugarcane juice and rotten fish, in capturing fruit-feeding butterflies across contrasting habitats (native grasslands and Restinga Forests) in the Pampa biome, southern Brazil. Using Van Someren–Rydon bait traps, we compared richness, abundance, diversity and species composition to evaluate how bait type and habitat influence assemblage structure. Contrary to expectations that rotten fish would attract more butterflies, fermented banana consistently had higher richness, abundance and diversity in both habitats. Rotten fish attracted fewer individuals and species, showing a narrower representation of butterflies. Species composition also differed between baits, with banana capturing a broader subset of the regional pool. Habitat influenced diversity patterns regardless of bait, in which Restinga Forests supported more diverse fruit-feeding butterfly assemblages with forest-dwelling species, whereas grasslands were dominated mainly by the Satyrini tribe. Our results demonstrate that fermented banana with sugarcane juice is the most effective bait for sampling fruit-feeding butterflies in subtropical regions.

This study quantified spatiotemporal variation and conditional co-occurrence networks among insect assemblages across nine commercial citrus orchards in East Java, Indonesia. Using a longitudinal repeated-measures design, one symptomatic fruit and five flowers were sampled or inspected monthly from 81 trees per orchard over three consecutive months (<i>n</i> = 2187 tree-by-sampling units). Fruit rearing yielded two tephritids (<i>Bactrocera dorsalis</i> and <i>Bactrocera carambolae</i>), drosophilids conservatively reported as <i>Drosophila</i> sp., and opiine parasitoids reported as <i>Fopius</i> sp., whereas floral observations quantified flower-associated thrips collectively. Generalized linear mixed models (GLMMs) controlled for orchard location, sampling period and repeated observations within trees. From 5236 recorded insects, total <i>Drosophila</i> was the most abundant group, whereas <i>B. dorsalis</i> dominated the tephritids. Insect abundance and occurrence varied strongly among orchards, whereas temporal fluctuations were taxon specific. Each additional adult <i>Bactrocera</i> emerging per fruit increased the odds of total <i>Fopius</i> occurrence by 16.8% (OR = 1.168, 95% CI = 1.026–1.329, <i>p</i> = 0.019), demonstrating a quantitative host-emergence–parasitoid recruitment relationship. The apparent parasitoid emergence ratio averaged 10.5%, showing spatial variation but no consistent temporal shift across the three sampling months. Conditional analyses revealed scale-dependent associations: <i>Bactrocera</i>-positive fruits had 2.66 times higher odds of producing drosophilids, and flower-associated thrips were positively associated with fruit-infesting <i>Bactrocera</i> at the tree level. In contrast, <i>B. carambolae</i> showed significant conditional segregation from <i>B. dorsalis</i> within fruits.

In this study, we evaluated the effect of parental microbial status on the performance of <i>Ceratitis capitata</i> offspring under chemical stress during larval development. Dysbiosis was induced in the parental generation through antimicrobial delivery, and offspring were reared on two diets: a control diet and a diet supplemented with juglone (0.5 mg/g), a phenolic compound with high redox activity found in <i>Juglans australis</i>. Developmental traits (pupal recovery and adult emergence) and survival (adult longevity) were assessed. Results showed that both parental antimicrobial treatment and exposure to juglone significantly affected performance during the egg–pupa transition, indicating that early larval development represents a critical stage under chemical stress. In contrast, no clear effects were observed on the pupa–adult transition, and emergence rates remained high across treatments. Conversely, the effects of chemical stress became more evident, significantly reducing adult longevity, particularly in offspring derived from aposymbiotic parents. Overall, these findings indicate that parental microbiota contributes to tolerance against plant defensive compounds throughout development and adult life, potentially facilitating exploitation of hosts with diverse phytochemical profiles.</p>\u0000 </div>","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"65 4","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149146549","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}

Based on these observations, we hypothesized that <i>N. elegantalis</i> is monandrous rather than monogamous, as previously suggested. We tested this hypothesis by determining whether (1) altered sex ratios affect mating frequency and (2) whether repeated mating opportunities impose a longevity cost on males while assessing the occurrence of female remating. Our results showed that (i) increasing the number of males did not increase the propensity of females to remate; (ii) males that copulated only once lived longer than those that copulated twice; and (iii) only four of the 96 females accepted a second mating opportunity despite repeated exposure to virgin males.

This study investigated the seasonal abundance of adult <i>S. litura</i> in the ORIA from May 2023 to November 2024 and used stable isotope analysis of adult tissues to infer larval host plant use, distinguishing between C3 and C4 plant sources. Despite expectations that dry-season cultivation of Bt cotton would not coincide with peak adult <i>S. litura</i> activity, substantial numbers of moths were collected within the ORIA during this period. Laboratory-reared insects that had developed exclusively on maize (C4), cotton (C3 non-legume) or pigeon pea (C3 legume) were used to establish baseline δ¹³C and δ¹⁵N values for each plant species. Analysis of δ¹³C values in the wing tissue of pheromone trap-collected <i>S. litura</i> adults enabled inference of larval host plant use. Stable isotope analysis revealed that most moths likely originated from C3 plants across the season with smaller numbers developing on C4 plants despite the widespread cultivation of C4 crops, such as maize and sorghum, in the region. These findings suggest that uncultivated C3 plants, including weedy species, may play an important role in sustaining <i>S. litura</i> populations within the ORIA.
