Different from H. patellifera, the H. chinensis individuals passed through 5–7 nymphal instars before emerging as adults. The body color of the H. chinensis nymphs was brownish gray in the first instar, whereas the second and later instars were green. Unlike H. chinensis, H. patellifera had mottled patterns all over its body during the first to third instar. The first to third instar nymphs of H. chinensis had mottled patterns on the femurs of their forelegs, which is a diagnostic characteristic that no native praying mantis species has. From the fourth instar, 7–10 dorsal spines were observed on the foreleg coxa of H. chinensis, whereas only 3 or 4 spines were observed in H. patellifera. These findings show that H. chinensis and H. patellifera can be distinguished in all nymphal instars.","PeriodicalId":11745,"journal":{"name":"Entomological Science","volume":"25 3","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44267635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines whether Lithosiini species, collected in a tropical rainforest of Borneo (nine species) and a temperate forest of Japan (eight species), feed on lichens as larvae, based on stable isotope analyses. As a result, the δ15N values for eight of nine Lithosiini species collected from Borneo were notably lower than those of nine co-occurring herbivorous non-Lithosiini species, and were similar to those of sympatric, lichen-feeding termites; however, δ13C and δ15N values of one Lithosiini species (Adites sp.) were significantly higher than those of the other moth species and similar to those of humus-feeding termites and predatory insects occurring at the same site. These results have suggested that the Lithosiini in the Southeast Asian tropical rainforests contain some species that feed on lichens as their larval main diet and at least one species whose larvae feed on humus or animal-derived materials. In contrast, the δ13C and δ15N values of all examined Lithosiini species (eight species) in the temperate forest have suggested that their larvae fed on plants and not on lichens. Our stable isotope ratio analysis presented quantitative evidence suggesting lichen-feeding by Lithosiini moths in a tropical rainforest without observation of feeding behavior during the larval stages.","PeriodicalId":11745,"journal":{"name":"Entomological Science","volume":"25 3","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48191304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in these systems, it is not always clear which plants were originally used as insect hosts, and how the focal insects adapted to the original host(s), before establishing the novel insect–host relationships. Henosepilachna vigintioctomaculata (Motschulsky) (Coleoptera: Coccinellidae) is a well-known pest of the potato Solanum tuberosum (Solanaceae), however its original host in Honshu, the main island of Japan, before the potato introduction is uncertain. A wild solanaceous weed, So. megacarpum, is the most likely candidate for the original host, although the use of this plant by H. vigintioctomaculata has never been recorded in Honshu. This study reports the occurrence of a H. vigintioctomaculata population depending almost solely on So. megacarpum at Yamagata, northern Honshu. Additionally, the host-use ability of this population was compared to that of a pest population under laboratory conditions. Based on the results obtained, it is discussed how the properties of beetles on So. megacarpum facilitated the use of the potato, assuming that So. megacarpum was the original host of H. vigintioctomaculata in Honshu.","PeriodicalId":11745,"journal":{"name":"Entomological Science","volume":"25 3","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41975102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there have been no quantitative studies on the feeding habits of the larval stage of this beetle. Revealing the feeding habits is indispensable for understanding the life history of C. rugosus. In the current study, we reared C. rugosus larvae on different prey taxa (Odonata nymph, fish, tadpole, and shrimp) and evaluated their growth and survival rates. Previous studies have shown that three congeneric Cybister species larvae feed mainly on invertebrates. However, all larval instars of C. rugosus were able to feed on invertebrates and vertebrates and grow. Thus, we considered C. rugosus to be a generalist compared to the other Cybister species. The larval periods were shorter for C. rugosus that fed on Odonata nymphs than on any other prey. Feeding different prey taxa had no significant effect on the body length of newly emerged adult males. However, the body length of newly emerged adult females was larger when the larvae fed on Odonata nymphs than when the larvae fed on fish. As in other Cybister species, we concluded that the Odonata nymph is an appropriate food from the viewpoint of increased growth rate in C. rugosus.","PeriodicalId":11745,"journal":{"name":"Entomological Science","volume":"25 2","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45839567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, approximately 40% of Dytiscidae members have been threatened with extinction in Japan, and Laccophilus is one of the genera with considerable decline. A description of the life history of these species and their ecological information will contribute to their conservation. In this study, I described the life history of Laccophilus lewisioides Brancucci, 1983 (Coleoptera: Dytiscidae: Laccophilinae) using rearing-based methods under laboratory conditions. I then compared the biology of the larval stages of this species to four Laccophilus species, L. vagelineatus Zimmermann, 1922, L. hebusuensis Watanabe & Kamite, 2020, L. yoshitomii Watanabe & Kamite, 2018, and L. kobensis Sharp, 1873. The developmental period for each immature stage at 26°C was as follows: first instar larva, 4–12 days (n = 16); second instar larva, 5–9 days (n = 15); third instar larva, 5–10 days (n = 15); landing to pupation, 2–3 days (n = 2); pupation to adult emergence, 4 days (n = 1); and landing to escape, 8–9 days (n = 14). The total larval period was significantly longer for L. lewisioides than for the other four Laccophilus species. The duration of larval period could be strongly related to the duration of stable water level in the reproductive habitat. The coloration of the larval stage varied between species groups, suggesting that the larvae adapt to the surrounding environment and show a camouflage effect. This is the first report on the immature stages in the life cycle of L. lewisioides.","PeriodicalId":11745,"journal":{"name":"Entomological Science","volume":"25 2","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48010614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, approximately 40% of dytiscids in Japan have been classified as threatened, and further knowledge on their life history is necessary to support conservation efforts. In this study, we collected adult Copelatus zimmermanni (Coleoptera: Dytiscidae) from an ephemeral rain pool and raised a generation under laboratory conditions. We then compared the larval period with two Copelatus species, C. parallelus and C. masculinus. Complete development (egg to adult) occurred in 39–61 days (n = 10) and comprised the following stages: egg (3–6 days, n = 20), first instar (3–8 days, n = 20), second instar (3–12 days, n = 15), third instar larvae (4–13 days, n = 14), and landing to escape (11–36 days, n = 10). The third instar and total larval periods of C. zimmermanni were significantly shorter than those of C. parallelus and C. masculinus. The differences in the duration of larval periods may be related to the permanence of water sources used as reproductive sites for each species. We suggest that the shorter developmental period of C. zimmermanni allows it to complete entire lifecycles even in highly ephemeral aquatic habitats.
