Manduca sexta and Pieris rapae, are sensitive to topically applied a-ter-thienyl (3) in the presence of light, whereas others such as Heliothis virescens are insensitive. a-Terthienyl (3) also showed potent activity (LD50 19 ppb) towards the light-exposed water-living larvae of the mosquito Aedes aegyptii [98]. 

M. salicifolia and displayed mosquitocidal activity on fourth instar Aedes aegyptii L. Culicidae at 15,25, 30,60, 80, and 100 ppm, respectively in 24 h [11, 12] (Table 2). Additionally, the sequential hexane, ethyl acetate, and methanol extracts of M. denudata and M. kobus var. stellata demonstrated growth inhibitory activity on gypsy moth larvae (Lymantria dispar) at 250 ppm [12], Citral and the phenylpropanoids are common in the essential oils of many plant genera. Citral, tram-anethole, and methyl chavicol have been detected in the essential oils of M. salicifolia and M. kobus [70, 71], Methyl eugenol has been detected in trace quantities by GC and MS in the leaf, branchlet, and essential oils from the flower bud of M. liliflora Desr. [72],... 

Purified I-labelled lectins have been interacted with cells of the mosquito, Aedes aegyptii, and with cells of human KB tumour. Relative to human KB cells, mosquito cells bound less of those lectins specific for L-fucose and d-galactose, which are terminal residues in many mammalian glycoproteins. 

We have examined a variety of plants, chosen for their traditional medicinal or insect control uses, for insecticidal and insect antifeedant properties. Our test insects are crop pests such as the tobacco cutworm Spodoptera litura, medically important insects (e.g the yellow fever mosquito Aedes aegyptii) or wood-destroying organisms such as the termite Reticulitermes speratus. 

Mosquito Larval toxicity Ten second-instar larvae of Aedes aegyptii were placed in wells containing an aqueous solution of plant extract (100 pg/ml) in two replicates, and their mortality recorded after 24H (27 C, 16 8 L/D). Controls received solvent only (100 pi, acetone or methanol).
