A New Invasive Fruit Fly Species from the Bactrocera dorsalis (Hendel) Group Detected in East Africa
TLDR
A new fruit fly species suspected to be from the Bactrocera dorsalis (Hendel) group (originating from Asia), was detected during routine field surveys in the Coast Province of Kenya, to determine the extent of spread of the new invasive species.

Parasitoids of medfly, Ceratitis capitata, and related tephritids in Kenyan coffee: a predominantly koinobiont assemblage.
TLDR
Most of the parasitoid species recovered during this study are capable of developing on C. capitata, while several also attack C. rosa, one of the notorious pests of tropical and subtropical fruits.

Geographic Distribution, Host Fruit, and Parasitoids of African Fruit Fly Pests Ceratitis anonae, Ceratitis cosyra, Ceratitis fasciventris, and Ceratitis rosa (Diptera: Tephritidae) in Kenya
TLDR
The availability of wild host fruit, sometimes supplemented by naturalized invasive plants or cultivated fruit, provided for year-round breeding of C. anonae and C. fasciventris, whereas indigenous fruit were sufficient for breeding ofC.

Indigenous Hosts of Ceratitis capitata (Diptera:Tephritidae) in Kenya
TLDR
The conditions for year-round breeding of medfly in indigenous fruits are present at the coast, and possibly in highland areas as well, as well as within two important host-plant families, Sapotaceae and Rubiaceae.

COLONIZATION OF FOPIUS CERATITIVORUS, A NEWLY DISCOVERED AFRICAN EGG-PUPAL PARASITOID (HYMENOPTERA: BRACONIDAE) OF CERATITIS CAPITATA (DIPTERA: TEPHRITIDAE)
TLDR
In the process of colonization it was determined that F. ceratitivorus oviposited into the eggs and recently hatched larvae of medflies and completed development in the hosts’ puparia, a relatively rare behavior among fruit fly parasitoids and, because tephritid eggs near the surface of fruits are particularly vulnerable to attack, one that might contribute to its success as a biological control agent.

Interspecific Competition, Parasitism, and Predation Affect Development of Aedes hendersoni and A. triseriatus (Diptera: Culicidae) in Artificial Treeholes
TLDR
The results suggest that interspecific competition, parasitism, and predation may be important factors in the life histories of treehole Aedes.

Malaria prevalence and use of self-protection measures against mosquitoes in Suba District, Kenya.
TLDR
Malaria was the leading cause of morbidity, constituting 42-48% of all illnesses clinically diagnosed at two health centres over a two-year period, and other common endemic diseases included infections of the upper respiratory and urinary tracts.
