Calling behaviour, in which generally females release volatile sex pheromones to attract the opposite sex, has been studied in several coleopteran families. Within the Coccinellidae, a putative calling behaviour has thus far only been identified in one species, <i>Harmonia axyridis</i>. In this study, a postulated calling behaviour in the seven-spot ladybird <i>Coccinella septempunctata</i> L. is described. We also investigated the effects of immediate mating history and the presence of conspecifics on this behaviour. Calling only occurs in females, and significantly fewer females called immediately after mating (observation started within 5 min). Of mated females that called, the number of calling bouts, durations per bout and total calling duration were not significantly different from females that had not immediately mated before. The presence of conspecific females or males did not significantly affect calling. This study provides a key step in furthering our understanding of the reproductive biology of ladybirds. Given that <i>C. septempunctata</i> is a widespread coccinellid, it is surprising that this behaviour has so far remained undescribed. This may be partly due to the infrequency of calling.</p>","PeriodicalId":11741,"journal":{"name":"Entomologia Experimentalis et Applicata","volume":"173 5","pages":"393-402"},"PeriodicalIF":1.4,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eea.13551","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate the behavioral response of the German cockroach to the repellence produced by δ-nonalactone and how this behavior changes according to nymph stage, age, sex, and presence or absence of antennae. Small, medium, and large nymphs, as well as adult males and females, were exposed to δ-nonalactone-treated filter paper. Small nymphs were the most affected by the repellent effect of δ-nonalactone. No differences were observed in the response between males and females, nor in adult males aged ranging between less than 6 h to 90 days old. Likewise, no repellent effects were observed in antennectomized cockroaches. These results suggest that small nymphs of <i>B. germanica</i> are more sensitive to the repellent effect of δ-nonalactone than other stages. Furthermore, the response to this repellent is independent of sex and age, and its receptors appear to be located exclusively on the antennae.

Plant pathogens that rely on insect vectors often have a positive density dependent relationship, with high vector abundance increasing pathogen spread. However, for pathogens that do not rely on insect vectors, the relationship can be more difficult to predict. Furthermore, environmental conditions, such as temperature and relative humidity, can indirectly alter pathogen spread by impacting vector reproduction or behavior. Therefore, studies examining the interactions between passively transmitted pathogens and potential insect vectors under varying environmental conditions are critical to understanding pathogen spread. Onion thrips, <i>Thrips tabaci</i> Lindeman (Thysanoptera: Thripidae), is the main insect pest of onion (<i>Allium cepa</i>) and co-occurs with many pathogens, including <i>Colletotrichum coccodes</i> Wallr (Glomerellales: Glomerellaceae), a fungal pathogen of onion. We conducted two experiments to understand how different densities of onion thrips and environmental conditions affect pathogen spread. To first determine how onion thrips density affects pathogen spread, we released 0, 5, or 25 onion thrips on <i>C. coccodes</i> inoculated plants, that were symptomatic, and allowed them to move between the symptomatic and asymptomatic plants. Next, to determine the effects of environmental conditions on pathogen spread, we altered temperature and relative humidity and added either 0 or 5 onion thrips to the experiment. Onion thrips dispersal, damage distribution, and pathogen spread 13 days after onion thrips were released were assessed for each experiment. Our results indicate that <i>C. coccodes</i> was only disseminated in the presence of onion thrips and dispersal increased at the 25 onion thrips density. Pathogen spread also increased at 33°C compared with 22°C, regardless of relative humidity.

To date, no study has investigated whether the benefits associated with life in large termite groups extend beyond the termites themselves and benefit other associated opportunistic organisms. Here, we evaluated the effect of the host termite group size of <i>Constrictotermes cyphergaster</i> (Silvestri, 1901) (Blattaria: Termitidae) on the survival time of two species of termitophilous beetles of the genus <i>Corotoca</i> Schiødte, 1853 (Coleoptera: Staphylinidae).

We observed that termite group size is an important factor for the survival of both tested species of termitophiles.

NCEs are critical to understanding ecological interactions broadly and in an applied manner, when addressing the efficacy of biological control within agroecosystems. In this study, we explore the impact of cues from the predator, <i>Hippodamia convergens</i> Guérin-Méneville (Coleoptera: Coccinellidae), on the probing and feeding behavior of <i>Diaphorina citri</i> Kuwayama (Hemiptera: Psyllidae), the Asian citrus psyllid (ACP), which transmits the causal bacteria of Huanglongbing (HLB) disease of citrus (Rutaceae). Due to wide-spread HLB incidence and insecticide resistance, it has become critical to better understand the activity of biological control agents within the HLB–ACP pathosystem. Utilizing electropenetrography (EPG), we investigated the feeding behavior of ACP exposed to the predator <i>H. convergens</i> or exposed to the chemical trails <i>H. convergens</i> produce while foraging. Overall, ACP detected <i>H. convergens</i> cues and responded by avoiding probing, although the extent of this response varied depending on the type of cue perceived. When <i>H. convergens</i> was present in the leaf but unable to reach the psyllid, ACP were slower to initiate probing and spent less time overall on probing and feeding from the xylem. In contrast, when exposed to <i>H. convergens</i> foraging cues without the beetle present, ACP initiated probing quicker than when the beetle was present and had a shorter total probing time compared to the control, with no other parameters being affected. Interestingly, the <i>H. convergens</i> chemical trail extracts, at two dosages, did not significantly influence ACP probing and feeding, except for a lower proportion of salivation and ingestion events into the phloem at the lower test dose. Our results suggest ACP exhibits avoidance behaviors in response to <i>H. convergens</i> cues, leading to a reduction in feeding, which suggests the maintenance of agroecosystem health through preservation of insect community diversity may be overlooked as an additive factor in vector management.</p>","PeriodicalId":11741,"journal":{"name":"Entomologia Experimentalis et Applicata","volume":"173 4","pages":"296-308"},"PeriodicalIF":1.4,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555027","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}
