The overall aim of this study was to investigate the role of honeydew from two aphids species, <i>Aphis fabae</i> Scopoli, 1763 and <i>Acyrthosiphon pisum</i> (Harris 1776) in the predatory behavior of <i>Adalia bipunctata</i> (Linnaeus 1758) and <i>Episyrphus balteatus</i> (De Geer 1776). Specifically, we aimed to (1) evaluate the impact of honeydew on <i>A. bipunctata</i> and (2) <i>E. balteatus</i> and on intraguild interactions (IGI) among them. Our results showed that the presence of honeydew enhanced the mobility of predators by stimulating foraging behavior. In addition, the number of aphids consumed was significantly higher in the presence of honeydew. Interestingly, the predators were more attracted to <i>A. fabae</i> in the presence of <i>A. pisum</i> honeydew. These findings highlight the key role of honeydew in intraguild relationships, altering the prey’s perception from being less preferred to becoming more appealing to predators, akin to their favored prey. These results provide interesting perspectives to improve aphid biological control.</p></div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"18 4","pages":"703 - 712"},"PeriodicalIF":1.2,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142413805","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}

We tested the effect of soil salinization on the induction of VOC emissions in wild cotton (<i>Gossypium hirsutum</i>) due to leaf damage and its consequences for the induction of defenses in neighboring plants. To this end, we performed a greenhouse factorial experiment where emitter plants were subjected to augmented soil salinity (vs. ambient salinity) and within each group emitter plants were subsequently exposed to simulated caterpillar damage (mechanical leaf damage treated with <i>Spodoptera frugiperda</i> oral secretion) or no damage (control). After 48 h of exposure, we collected VOCs released by emitter plants and then damaged the receivers and collected their leaves to measure levels of chemical defenses (terpenoid aldehydes of known insecticidal effects). We found an interaction between leaf damage and salinization for two groups of VOCs released by emitters (sesquiterpenes and other aromatic compounds), whereby damaged receivers had higher emissions than control plants under ambient but not salinized soil conditions. We also found that, upon being damaged, receiver plants exposed to damaged emitters exhibited a significantly higher concentration of heliocides (but not gossypol) than control plants. However, salinization did not alter this VOC exposure effect on receiver induced responses to damage.

Here, we assessed whether Asteraceae pollen spines are detrimental to generalist bees independently of any effects of pollen chemistry. To do so, we administered three pollen diet treatments to queenless bumble bee microcolonies: one treatment incorporated sporopollenin exine “shells” extracted from spinous (echinate) sunflower pollen; a second incorporated chemically identical shells from non-spinous mixed pollen; and the third was a control diet with no added exine. We found that the presence of pollen spines in the diet significantly reduced larval growth, beyond the reduction caused by adding exine to the diet. However, we observed no effect of pollen spines on the survival of adult workers or larvae, nor did we find substantially increased intestinal damage in adults.

Geographical variation in environmental factors can influence the diversity of pollinators and thus, affect the structure of pollination networks. Given the current global climate change, understanding the variation of pollination network structure along environmental gradients is vital to predict how global change will affect the ecological interaction processes. Here, we used a global plant-pollinator interaction data collection by the same sampling method at the same period to explore the effects of elevation, latitude, and plant richness on the structure and robustness of pollination networks. We analyzed a total of 87 networks of plant-pollinator interactions on 47 sites from 14 countries. We conducted a piecewise structural equation model to examine the direct and indirect effects of elevation, latitude, and plant richness on the network robustness and analyzed the function of network structure in elucidating the relationship between robustness and these gradients. We found that plant richness had both positive effects on robustness under random and specialist-first scenarios. Elevation, latitude, and plant richness affected network connectance and modularity, and ultimately affected network robustness which were mediated by nestedness under specialist-first and random scenarios, and by connectance under the generalist-first scenario. This study reveals the indirect effects of elevation, latitude, and plant richness on pollination network robustness were mediated by nestedness or connectance depended on the order of species extinctions, implying that communities with different pollination network structures can resist different extinction scenarios.</p></div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"18 3","pages":"389 - 401"},"PeriodicalIF":1.2,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140731401","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}
