To sustain agricultural development in Africa, innovative strategies for addressing a myriad of biotic and abiotic constraints facing the agricultural systems must be established. One current biotic stress is the mango infesting fruit flies. In the effort to contain the widely spreading and damaging invasive species of tephritid fruit fly (Bactrocera dorsalis) (Hendel), an area-wide integrated pest management (IPM) program is being promoted in the horticultural sub-sector in sub-Saharan Africa. Such a new technology in which farmers have limited information before commercialization may have diffusion paths that are different from the often-assumed sigmoid (or “s”) shaped curve. We apply the descriptive and econometric analysis of ex ante and ex post integrated fruit fly management used by mango farmers in Kenya and Ethiopia. The results reveal that this technology has a relatively high adoption rate and high prospects for adoption growth in Kenya compared to Ethiopia in the near future.

The Role of parasitoid in controlling the population of fruit flies (Bactrocera dorsalis Complex.) (Diptera: Tephritidae) who attacked mangoes (Mangifera indica L) in Buleleng Regency. Thisresearch was conducted with the aim of knowing the role of parasitoids in controlling the population of fruit flies (Bactrocera dorsalis Complex.) (Diptera: Tephritidae) on mango plants (Mangifera indica L.) in Buleleng Regency. Field research was carried out at the Buleleng mango plantations while laboratory research was carried out at the Integrated Pest Management and Plant Disease Laboratory from April to July 2019.Field research was carried out at  the Buleleng mango plantations while laboratory research was carried out at the Integrated Pest Management laboratory and  was  carried out  from  April  to  July 2019.  Determination of the location of sampling  is  done  diagonally  and  fruits  infested  larvae  was  taken  purposively. The results showed that there were three species of fruit flies that attacked mango in Buleleng Regency, namely B. carambolae, B. papayae and B. occipitalis with an abundance of B. carambolae 39.3%, B. papayae 64.4% and B. occipitalis 0.3% and found three types of parasitoids namely Fopius sp, Diachasmimorpha sp. and Opius sp. The role of parasitoids in controlling fruit flies is still low when viewed from the parasitization rate of the three parasitoids namely Fopius sp. (2,24%), Diachasmimorpha sp. (1,9%), and Opius sp. (0,46%).

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
