The chemotactic effect of Phlebotomus duboscqi (diptera: psychodidae) salivary gland lysates to murine monocytes
(University of NairobiDepartment of Zoology, 1995-10)The possibility that salivary gland lysates of Phlebotomus duboscqi are able to attract vertebrate monocytes was investigated. In vitro studies showed that salivary gland lysates of P. duboscqi, the vector of Leishmania ... -
The Effects of a DNA Virus Infection on the Reproductive Potential of Female Tsetse Flies, Glossina morsitans centralis and Glossina morsitans morsitans (Diptera: Glossinidae)
(University of NairobiSchool of Biological and Physical Sciences, 1998)Reproductive anomalies associated with the tsetse DNA virus infection in the female tsetse hosts, Glossina morsitans centralis Machado and Glossina morsitans morsitans Westwood, inoculated with the virus during the 3rd ... -
The Effects of a Tsetse DNA Virus Infection on the Functions of the Male Accessory Reproductive Gland in the Host Fly Glossina morsitans centralis (Diptera; Glossinidae)
(University of Nairobi,School of Biological and Physical Sciences, 1999)Freshly deposited third instar Glossina morsitans centralis larvae were infected with the tsetse DNA virus by microinjection, and at emergence adult males were separated from the females and fed on rabbit blood every second ... -
Long-term use of permethrin-impregnated nets does not increase Anopheles gambiae permethrin tolerance
(University of NairobiDepartment of Zoology, 1996)Previous use of permethrin-impregnated bednets (mosquito nets) and curtains in four Kenyan villages for one year, 1990-91, raised the permethrin LT50 of Anopheles gambiae to 2.4-fold above its baseline value, designated ... -
Growth-inhibiting and larvicidal effects of Melia volkensii extracts on Aedes aegypti larvae
(University of NairobiDepartment of Zoology, 1988)Extracts from dry Melia volkensii fruits contain growth-inhibiting activity against larvae of the mosquito Aedes aegypti. The active fraction may be eluted from silica gel using hexane-ethyl acetate (1:1, v:v). At a ... -
Reduced susceptibility of Anopheles gambiae to permethrin associated with the use of permethrin-impregnated bednets and curtains in Kenya
(University of NairobiDepartment of Zoology, 1994)Susceptibility of the malaria vector Anopheles gambiae to permethrin decreased following the installation of mosquito nets impregnated with 0.5 g permethrin per square metre in four villages near Kisumu, Kenya. During the ... -
Elevated oxidase and esterase levels associated with permethrin tolerance in Anopheles gambiae from Kenyan villages using permethrin-impregnated nets
(University of Nairobi,School of Biological and Physical Sciences, 1999)The permethrin tolerance (PT) of a population of the mosquito Anopheles gambiae (Diptera: Culicidae) increased following the introduction of permethrin-impregnated nets for malaria control in certain villages near Kisumu, ... -

Leaf storage conditions and genomic DNA isolation efficiency in Ocimum gratissimum L. from Kenya
(University of NairobiSchool of Biological and Physical Sciences, 2008)Storage of plant tissues for DNA is important to avoid degradation of DNA. Preliminary studies were conducted on Ocimum gratissimum L. in order to establish the storage conditions for the collected samples before DNA ... -
Development of a Gravid Trap for Collecting Live Malaria Vectors Anopheles gambiae s.l.
(University of NairobiSchool of Biological and Physical Sciences, 2013)Background Effective malaria vector control targeting indoor host-seeking mosquitoes has resulted in fewer vectors entering houses in many areas of sub-Saharan Africa, with the proportion of vectors outdoors becoming ... -
