Two new bee-killing flies from Brazil (Insecta: Diptera: Phoridae: Melaloncha)
BACKGROUND The genus Melaloncha is a large group of species of parasitoid phorid flies that attack Hymenoptera, mostly stingless bees (Meliponinae, Apidae) in the Neotropical Region. NEW INFORMATION Two new Brazilian species, Melaloncha (Melaloncha) peacockorum sp. n. and Melaloncha (Udamochiras) nielsi sp. n., are described and their identification clarified.
متن کاملHost Specificity in Two Additional Pseudacteon Spp. (diptera: Phoridae), Parasitoids of Solenopsis Fire Ants (hymenoptera: Formicidae)
We tested the host specificity of two South American Pseudacteon phorid flies, P. obtusus Borgmeier and P. borgmeieri Schmitz, on North American colonies of the red imported fire ant, Solenopsis invicta Buren, and the tropical fire ant, S. geminata (F.). Sequential host specificity tests conducted in the laboratory indicated that P. obtusus was highly specific to S. invicta . In individual tria...
متن کاملHymenoptera: Vespidae)
Workers in many insect societies interact via body contact with their nest mates, and social biting and other forms of contact may play a general role in regulating task performance. Here I present evidence that social biting affects task performance without direct reproductive conflict in Polybia occidentalis, a swarm-founding eusocial wasp. Polybia occidentalis workers engaged in social bitin...
متن کاملCastes and asynchronous colony cycle in Polybia bistriata (Fabricius) (Hymenoptera: Vespidae).
Neotropical swarm-founding wasps, the Epiponini, are an outstanding group of social insects whose societies are polygynic and complex nest builders. Caste dimorphism in these wasps ranges from incipient to highly distinct. Morphometric analyses of nine body parts, ovarian status, relative age and development of the 5th gastral sternite gland (Richards' gland) of Polybia bistriata Fabricius were...
متن کاملAn adaptive view of caste differentiation in the neotropical wasp Polybia (Trichothorax) sericea Olivier (Hymenoptera: Vespidae).
The tribe Epiponini comprehends the swarm-founding Neotropical wasps, with several species endemic to Brazil, which are extremely important in studies of social evolution of wasps. The Epiponini diverge in several ways from the definitions of high eusociality, since caste syndromes range from species without morphological caste differentiation to those with complete caste dimorphism, and all sp...
