“…Essential oils possess a wide spectrum of biological activities including anti-microbial, fungicidal, insecticidal, insect repellant, herbicidal, acaricidal, and nematicidal (Noutcha et al, 2016). Seo et al (2012) stated that C. copticum can be used as a botanical insecticide.…”

An experiment was carried out, firstly, to determine the possible toxicity of (Apiaceae) extract against (Diptera: Culicidae), and, secondly, to study the histopathological alterations in the midgut of as a result of treatment with extract Larvicidal and ovicidal activities of extract against the larvae of was determined according to World health organization (WHO). The inhibition effect of was assessed by determining the mortality of the treated larvae and eggs. The histopathological effect of the extracts on midgut epithelium of the larvae was examined under both light and transmission electron microscopy. The crude extract of exerted 100% mortality for after 24 h at 200 μm/ml, and zero hatchability (100% mortality) at 150 μm/ml for . The histopathological study showed that larvae treated with extract had cytopathological alterations of the midgut epithelium. The study provided information on various effects of extract against.

Background Plant oils possess biological activities which offer tremendous potential for disease vector management. This study investigated the bioactivity of selected insecticidal plant oils against Anopheles gambiae s.s. Kisumu Susceptible Strain (KSS) mosquitoes. The plant oils from leaves of Hyptis suaveolens, Ocimum gratissimum, Nicotiana tabacum, Ageratum conyzoides and fruit peels of Citrus sinensis were extracted and the major chemical components analysed using coupled gas chromatography-mass spectrometry (GC-MS). The spatial toxicity effects of the plant oils were tested at different concentration (0.1 mg/ml, 0.3 mg/ml and 0.5 mg/ml) against An. gambiae s.s. KSS in a Peet-Grady Chamber. Deltamethrin was used as the positive control. Results D-Limonene was the major chemical component found in Ci. sinensis and Ni. tabacum. Prococene I was the major chemical component in Oc. gratissimum while P-Xylene had the highest percent composition in Ni. tabacum. The control (Deltamethrin) and 0.3 mg/ml concentration of oil from Oc. gratissimum elicited a 100% knockdown on An. gambiae s.s. KSS. At 0.5 mg/ml, oils from Ci. sinensis, Oc. gratissimum and Ni. tabacum elicited significantly (P > 0.05) the same knockdown effect (100%) as the control on An. gambiae s.s. KSS. After 24hrs post-exposure, all the plant oils evaluated elicited 100% mortality on An. gambiae s.s. KSS at both 0.3 and 0.5 mg/ml. The lowest knockdown times KdT50 (34.80 minutes) and KdT95 (92.50 mins) were noted at the lowest concentration (0.1 mg/ml) of oils from Ni. tabacum which was better compared to the control (36.1 and114.9 mins respectively) against An. gambiae s.s. KSS. Conclusions Oc. gratissimum and Ni. tabacum displayed excellent spatial toxicity capabilities against An. gambiae s.s. KSS and can be incorporated into the management of malaria vectors in Nigeria.
