Commercial M. rotundata populations are employed to pollinate North American alfalfa for seed production. This wasp can be prolific when using M. rotundata as a host and can reduce or destroy bee stocks. Hundreds of M. acasta female offspring can develop in a single M. rotundata cell and disperse to infest other cells, producing thousands of more parasitoids. In this study, we determined (i) upon what bee life stages M. acasta females choose to lay eggs and if those eggs ultimately become adults and (ii) M. acasta female longevity when exposed to various resources within M. rotundata cells. We found that M. acasta females lay eggs on M. rotundata prepupae and pupae and that those eggs can hatch and survive to adulthood. Eggs are not laid on early instar bee larvae; eggs laid on adults do not survive. Average female life span is 5 days without feeding, 8\u20139 days if a pollen\u2013nectar provision is available while the bee develops through larval stages, and 34 days if the wasp can feed on prepupal hemolymph. Wasp females can emerge from bee cells several days after trays of cells are taken to fields. Therefore, adult females could survive long enough for new bee offspring to become prepupae. Our findings support a better understanding of host life stage preference and the longevity of M. acasta females that can inform the timing of the implementation of possible control measures.<\/jats:p>","DOI":"10.1093\/jisesa\/iead031","type":"journal-article","created":{"date-parts":[[2023,5,25]],"date-time":"2023-05-25T00:10:32Z","timestamp":1684973432000},"source":"Crossref","is-referenced-by-count":3,"title":["<i>Melittobia acasta<\/i> (Hymenoptera: Eulophidae) female longevity and life stage-dependent parasitism using commercially managed <i>Megachile rotundata<\/i> (Hymenoptera: Megachilidae) as hosts"],"prefix":"10.1093","volume":"23","author":[{"given":"Alan R","family":"Anderson","sequence":"first","affiliation":[{"name":"Department of Biology, Utah State University , Logan, UT 84322 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9870-0018","authenticated-orcid":false,"given":"Ricardo A","family":"Ramirez","sequence":"additional","affiliation":[{"name":"Department of Biology, Utah State University , Logan, UT 84322 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4393-6816","authenticated-orcid":false,"given":"J","family":"Earl Creech","sequence":"additional","affiliation":[{"name":"Department of Plants, Soils and Climate, Utah State University , Logan, UT 84322 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1471-3450","authenticated-orcid":false,"given":"Theresa L","family":"Pitts-Singer","sequence":"additional","affiliation":[{"name":"USDA ARS Pollinating Insects Research Unit , Logan, UT 84322 , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,5,31]]},"reference":[{"key":"2023053115053698200_CIT0001","author":"Alberta Seed Commission.","year":"2010"},{"key":"2023053115053698200_CIT0002","doi-asserted-by":"crossref","DOI":"10.1093\/aesa\/saad011","article-title":"Life cycle of Melittobia acasta (Hymenoptera: Eulophidae) using Megachile rotundata (Hymenoptera: Megachilidae) as a host","author":"Anderson","year":"2023","journal-title":"Ann Entomol Soc Am"},{"issue":"8","key":"2023053115053698200_CIT0003","doi-asserted-by":"crossref","first-page":"1826","DOI":"10.1111\/pce.12342","article-title":"Experience-based modulation of behavioral responses to plant volatiles and other sensory cues in insect herbivores","volume":"37","author":"Anderson","year":"2014","journal-title":"Plant Cell Environ"},{"key":"2023053115053698200_CIT0004","doi-asserted-by":"crossref","first-page":"349","DOI":"10.1017\/S003118200001026X","article-title":"On the life history of Melittobia acasta, Walker;
