Topic: BIOACTIVITY, BIOSAFETY AND BIOSECURITY RELATING TO EFFICACY OF NATURAL PLANT PRODUCTS AGAINST INSECTS OF AGRICULTURAL AND PUBLIC HEALTH IMPORTANCE
Description: My research interests are focused on the following:1. Exposing various insects species of public health importance to extracts to the powders, ethanol extracts, petroleum ether extracts, aqueous extracts, and essential oils from leaves, roots, bark, root bark etc of various plant species locally available in Nigeria for their insecticidal, repellency, growth regulatory, ovicidal, larvicidal and other effects on test species. These involves exposing the test insects species of known developmental stages and age to test formulations over specific time interval in standard acute and chronic bioassays in laboratory and field studies. Prior to exposures, stock cultures of test insect species are raised and maintained in the laboratory being kept away from any toxicant for many generations. Studies are carried out under measured ambient laboratory conditions of temperature and relative humidity using various life stages of the test insect species including Anopheles gambiae sl, Musca domestica and Periplaneta americana, in standard bioassays. 2. Biosafety, Biosecurity and Laboratory Biorisk Management. My laboratory work on insects of public Health Importance have led to interests in these emerging issues with particular focus on Biosafety and biosecurity relating to zoonotic diseases vectored by insects, Laboratory Biorisk Management and management of laboratory and bioharzadous Wastes from animals, public health facilities etc.

BIOACTIVITY OF LOCALLY AVAILABLE BOTANICALS AGAINST MOSQUITO SPECIES DIPTERA; CULICIDAE IN THE LABORATORY
My ongoing research is on the control of insect vectors of human and veterinary diseases using plant natural products as alternatives to orthodox insecticides. These diseases take huge economic toll in terms of morbidity and mortality on Man and animals. There is therefore an urgent need to break the chain of transmission through control of mosquitoes and other arthropods serving as vector for the parasites. The objective of this research is to evaluate the ovicidal, larvicidal, insecticidal and repellency effects of Locally Available Botanicals LABs namely Tecrum flavum, Tectonia grandis, Bahama bahama, Hyptis suavoellens etc as powders, solvent extracts and essential oils for control of mosquitoes, ticks and other arthropods. My previous studies published in well-rated local and international journals have shown that some LABs may serve as credible sources of compounds which can be reliable alternatives to extant orthodox insecticides compounded in foreign countries and imported into Nigeria. There are copious literature on the application of botanicals against insects as control agents but there is a dearth of studies on these applications in the localities selected as the study sites of this research. Moreover, the studies are laboratory test with limited applicability in field and communal usage. Validated questionnaires have already been administered on residents of Ijanikin and Gbethrome, Lagos State to determine their knowledge, perception and use of insecticide-treated nets, especially with bednets treated with LABs. Also, plant materials are already being collected and prepared into test formulations against the insect species. The study also includes chemical analyses of test botanicals for constituents using Gas Chromatography Mass Spectroscopy techniques and analyses of data gathered. In addition to the foregoing, I have spearheaded research on the identification of arthropod-borne pathogens causing diseases in animals and humans.
