Male production by laying workers in queenright colonies of Melipona favosa (Apidae, Meliponinae)

, : Male production by laying workers in queenright colonies of Melipona favosa (Apidae, Meliponinae). Biology and evolution of social insects: 89-97

Laying workers of M. rufiventris can produce different eggs: male-producing eggs (or reproductive worker eggs, RWEs) and trophic worker eggs (TWEs). This has now been confirmed for M. favosa. In experimental M. favosa colonies without a queen, workers always produced RWEs. In queenright colonies workers generally produced TWEs.

Mice which were given a primary infection consisting of male or female Schistosoma mansoni cercariae alone failed to acquire the same degree of resistance against homologous challenge as did mice with a bisexual primary infection. The degree of re...
