For gynodioecious plant populations, which consist of two sexes (female-non-pollen-producing flowers and hermaphroditic flowers), bee–flower interactions also have ecological implications, including the maintenance of females. We evaluated bee performance on a gynodioecious globose cactus, Coryphantha elephantidens, to determine how bees interact with different sexes and if they visit and pollinate them differently. We recorded videos of visits to both hermaphroditic and female flowers (n = 26 flowers of each sex). From these videos, we registered and analyzed bee visitation rate, handling time, and behavior using non-parametric models, generalized linear models, and chi-squared tests. Our findings revealed 15 species of visiting bees, with the most frequent being Augochlorines (59%), Ashmeadiella opuntiae (21%), and Apis mellifera (13%). Augochlorines were focused on collecting pollen and rarely touched stigmas, while A. mellifera promoted self-pollination, as they contacted stigmas after contacting the stamens. The solitary bee A. opuntiae emerged as the most effective pollinator, promoting cross-pollination by visiting both sexes with equal frequency. Since both sexes of C. elephantidens lack nectar and female flowers lack pollen, we suggest that female flowers are pollinated by deceit. This cactus species exhibits functional specialization, as only three bee species significantly contribute to pollination. Although the other remaining bees are not effective pollinators, their presence suggests this cactus is an important host for a wide variety of wild bees.</div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"18 5","pages":"1111 - 1122"},"PeriodicalIF":1.2,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142451123","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}

To bridge this gap, our study aimed to consolidate existing knowledge by systematically mapping global scientific articles on arthropods associated with cacao cultivation. Using advanced text mining and structural topic modeling, we identified eight thematic categories in 552 articles, with 69.6% published between 2000 and 2023. Geographically, studies were concentrated in America (38.2%), Africa (34.6%), and Asia (20.8%). Publications showed a surge across most topics, providing updated insights into their distribution. Research in America focused on beetles, parasitoid hymenopterans, ants, pollinating dipterans, and arachnids. Conversely, substantial publications addressed pest arthropods, including hemipterans in Africa, the Cocoa Pod Borer in Asia, and other pests in America and Africa. Through our systematic analysis, we uncovered key topics shedding light on arthropod biology and ecological interactions, highlighting the importance of agroforestry systems for conserving diversity and promoting ecosystem services like pollination and biological control.

Narrow interactions with oligolectic bee pollinators that exhibit specialized pollen foraging are characteristic for flowers of Loasoideae. We investigated the pollination system of Blumenbachia catharinensis, an endemic to the Araucaria Forest of Brazil, with a specific focus on the role of the newly described oligolectic bee Rhophitulus ater (Andrenidae). We described the pollen presentation characteristics of B. catharinensis, analyzed the foraging strategy of R. ater and its role as pollinator and determined which bee species obtains the most pollen. Females of R. ater were the dominant flower visitors (> 90% of visits) and the first to remove the pollen from > 95% of the anthers, thus gaining almost the entire pollen content of B. catharinensis flowers. During foraging flights, females always approached and hovered at a short distance in front of flowers. After ~ 80% of floral approaches, they rejected visits, particularly when no pollen-carrying anther was available. Thus, this floral inspection is a constant behavioral trait of the pollen foraging strategy of R. ater. Curiously, in more than half of the visits to pistillate-phase flowers, females actively collected the deposited allochthonous pollen present on stigma and style.

Considering the importance of plant chemicals as cues for insects in their search for both prey and shelter, we hypothesized that volatiles from guava fruit (Psidium guajava) play these roles for the earwig E. annulipes. First, in arena tests, we investigated the role of guava fruits as shelters to earwigs by examining their preference for mechanically perforated guava fruits (MPF) or artificial fruits made from plastic (AF), as well as for MPF versus fruits infested with Ceratitis capitata larvae (IF), over a time course. Subsequently, we evaluated the earwigs’ attraction and preference for volatiles emitted from uninfested guavas (UF), MPF, or IF. The results of the arena tests showed that the earwigs preferred MPF over AF to shelter, but had no preference between MPF and IF up to 33 h; however, from 45 h after release, more females sheltered in MPF. The olfactory tests showed that the female earwigs recognized volatiles from MPF and IF, but preferred volatiles emitted by IF over those emitted by UF or MPF. Thus, our results suggest that females of E. annulipes use volatile chemical cues to locate guava fruits, which serve as shelter, and that despite being initially attracted by the odors of fruit-fly-infested guava fruits, they prefer to shelter in uninfested fruits after predation.</div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"18 5","pages":"917 - 926"},"PeriodicalIF":1.2,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142451077","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}

Although the flowering periods of these species overlapped, flower visitor communities were very dissimilar among Anthurium species, sharing only a tiny fraction of insects that function as connectors among species in the network. The partition of potential pollinators in a fine temporal scale occurred through the rewiring of shared flower visitors to the most abundant flowering Anthurium species. On the other hand, a high number of inflorescences attracted larger abundance and richness of insect visitors.

We found that in the lab, DBM larvae showed a clear preference for younger leaves (leaf positions 3–5). However, when C. vestalis was present, regardless of whether the parasitoids could touch the DBM, larvae were less likely to be on those preferred leaf positions. This change in larval distribution was also replicated when potted cabbage plants containing DBM larvae were placed in cabbage fields.

It has been mainly deployed as an insectary plant; few studies have been conducted on its use as a trap plant.

Hand-pollinated flowers had higher seed set which negated the effect of petal orientation, suggesting that insect pollination may have driven seed set. In this study, we observed insect visitors and their effects on seed set in R coulteri’s native range. Plant performance was again limited by pollen such that experimentally adding outcross pollen increased seed set. Native and introduced bees showed no proclivity toward either petal orientation. However, the most common visitor, a native beetle (Lytta auriculata), was strongly biased toward approaching and ultimately accepting flowers with vertical petals that provided shade. Beetles were covered with R. coulteri pollen. Flowers bagged with only beetles for 24 h produced as many seeds as controls left open to all visitors. However, beetles also consume pollen and chew petals. Flowers with vertical petals received more beetle damage and damaged flowers produced 35% fewer seeds than those without chewed petals. Despite the potential role of beetles as pollen vectors, flowers with vertical petals did not experience higher seed production.
