The economic importance of Bactrocera oleae (Rossi) and the problems associated with insecticides make necessary new management approaches, including deeper biological knowledge its relationship landscape structure. Landscape complexity reduces B. abundance in late summer–autumn areas high dominance olive groves, but effect structure spring less dominated by groves has not been studied. It is a...

In 2003, a new fruit fly pest species was recorded for the first time in Kenya and has subsequently been found in 28 countries across tropical Africa. The insect was described as Bactrocera invadens, due to its rapid invasion of the African continent. In this study, the morphometry and DNA Barcoding of different populations of B. invadens distributed across the species range of tropical Africa ...

Representatives of several families of insect viruses were tested for growth and pathogenicity in the olive fruit fly, Dacus oleae Gmel. The viruses included nuclear polyhedrosis viruses, an iridovirus, two picornaviruses, and Trichoplusia ni small RNA virus (a member of the Nudaurelia beta family), in addition to two naturally occurring viruses of the olive fruit fly. Two viruses, one of the t...

Three natural populations of Dacus oleae have been sampled for six electrophoretically detected polymorphic genes. The distribution of the allele frequencies in the different populations were analyzed by the method suggested by Lewontin and Krakauer (1973) (the various in space one) in order to test for selective neutrality. This method, however, which in our case showed that one or more genes ...
