GONCALVES<br \/>\nBRAZIL<br \/>\n<em>Varroa jacobsoni<\/em>, an ectoparasite mite of <em>Apis<\/em>, causes serious damage to colonies of <em>A. mellifera<\/em> while in those of <em>A. cerana<\/em>, the original host, this is not the case. Koeniger et al. (1981) observed that in <em>A. cerana<\/em> the mites only reproduce in drone cells, while in <em>A. mellifera<\/em> there is reproduction in both worker and drone cells. It\u2019s possible that the resistance of <em>A. cerena<\/em> to this mite is due to this biological characteristic.<br \/>\nBased on this information and knowing that the cells of workers of Africanized bees are smaller than those of European bees, we examined the infestation rate and reproduction of <em>Varroa<\/em> in small pieces (+\/-300 cells) of Africanized and Italian built combs.<br \/>\nThe worker combs of Africanized bees had a mean of 4.50 to 4.77 mm and a volume of 0.187 ml, while for Italian bees the values were 5.07 to 5.11 and 0.255.<br \/>\nThe mean weight of 18-19-day old Africanized worker pupae was 94.6 mg, and their infestation rate was 4.8%, while for Italians the mean weight was 111.7 mg, and 11.5% of the cells were infected.\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The Effect of The Size of Honey Bee Cells on The Rate of Infestation by Varroa Jacobsoni The Effect of The Size of Honey Bee Cells on The Rate of&hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[211],"tags":[],"class_list":["post-992","post","type-post","status-publish","format-standard","hentry","category-historical-data-on-the-influence-of-cell-size"],"_links":{"self":[{"href":"https:\/\/beefree.es\/index.php?rest_route=\/wp\/v2\/posts\/992","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beefree.es\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beefree.es\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beefree.es\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/beefree.es\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=992"}],"version-history":[{"count":1,"href":"https:\/\/beefree.es\/index.php?rest_route=\/wp\/v2\/posts\/992\/revisions"}],"predecessor-version":[{"id":4301,"href":"https:\/\/beefree.es\/index.php?rest_route=\/wp\/v2\/posts\/992\/revisions\/4301"}],"wp:attachment":[{"href":"https:\/\/beefree.es\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=992"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beefree.es\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=992"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beefree.es\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=992"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
