Cross-order transfer of Wolbachia from Muscidifurax uniraptor (Hymenoptera: Pteromalidae) to Drosophila simulans (Diptera: Drosophilidae)

Article Abstract:

An experiment in which T-Wolbachia bacteria were transferred from the parasitoid Muscidifurax uniraptor to Drosophila simulans has been carried out. The infection could be found in the new host down through several generations. Polymerase chain reaction tests were used for detection. Specific effects on the host were not detected nor were the bacteria maintained in a stable fashion. Wolbachia commonly occur in arthropods and can bring on different effects, among them feminization (F), thelytoky (T), and cytoplasmic incompatibility (CI).

The resolution of Californian populations of Liriomyza huidobrensis and Liriomyza trifolii (Diptera: Agromyzidae) using PCR

Article Abstract:

Californian populations of Liriomyza huidobrensis and Liriomyza trifolii (Diptera: Agromyzidae), important vegetable pests in the state, have been resolved using PCR. Populations of the species differ in impact by region in the central and southern parts of the state. No evidence was found for further populations or hybrid populations in central and southern California. Geographical differences explained the distribution of populations of L. huidobrensis. Factors in L trifolii population distribution differences were less easy to see.

The origin and evolution of stereotyped patterns of macrochaetes on the nota of cyclorraphous Diptera

Article Abstract:

The origin and evolution of stereotyped patterns of macrochaetes on the nota of cyclorraphous Diptera are discussed. The discovery that macrochaelte patterns are restricted by sites of attachment of an invariant pattern of flight muscles indicate that early proneural gene expression in any lineage could have led to convergent patterns.
