We conducted a study to determine the physiological status of adults trapped by a sex pheromone and floral odor. In the immigrant group, the number of males trapped by the floral odor was greater than the number caught by sex pheromone trapping. The volume of testes was similar in the above two trapping methods but was smaller than in the sweep net method. The ovary developmental grade, mating rate, and number of matings of females caught in floral odor trap were higher than in those caught in the sweep net. In the local breeding group, the number of males trapped by sex pheromones was greater than the number trapped by the floral odor. The volume of testes was smaller in the floral odor trap compared to the pheromone trap group, with the largest in the sweep net group. The ovarian developmental grade, mating rate, and number of matings of females were significantly higher in the floral odor trap group than in the sweep net group. In the emigrant group, the adult olfactory response to the sex pheromone and floral odor was low. The volume of testes was larger in the sweep net group compared to the moths caught by floral odor trapping. The number of eggs laid by female immigrants trapped by the floral odor and sweep net was similar, while the number in the local breeding group was greater in moths caught with the sweep net in comparison with those caught by the floral odor trap. The difference in egg hatchability between the two trapping methods in both immigrants and local breedings was not significant.<\/jats:p>","DOI":"10.3390\/insects15090637","type":"journal-article","created":{"date-parts":[[2024,8,26]],"date-time":"2024-08-26T03:32:01Z","timestamp":1724643121000},"page":"637","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Physiological Status of Rice Leaf-Roller Cnaphalocrocis medinalis (Lepidoptera: Crambidae) Adults Trapped by Sex Pheromone and Floral Odor"],"prefix":"10.3390","volume":"15","author":[{"given":"Jianfei","family":"Lu","sequence":"first","affiliation":[{"name":"Zhejiang Provincial Plant Protection, Quarantine and Pesticide Management Station, Hangzhou 310029, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoming","family":"Yao","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Plant Protection, Quarantine and Pesticide Management Station, Hangzhou 310029, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Shen","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Plant Protection, Quarantine and Pesticide Management Station, Hangzhou 310029, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Du","sequence":"additional","affiliation":[{"name":"Ispxtech Inc., Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qianshuang","family":"Guo","sequence":"additional","affiliation":[{"name":"Institute of Pesticide and Environmental Toxicology, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6463-385X","authenticated-orcid":false,"given":"Yongjun","family":"Du","sequence":"additional","affiliation":[{"name":"Institute of Pesticide and Environmental Toxicology, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,25]]},"reference":[{"key":"ref_1","first-page":"129","article-title":"A Bibliography of Rice Leaffolders (Lepidoptera, Pyralidae)","volume":"9","author":"Khan","year":"1988","journal-title":"Insect Sci.
