Activity of Melia azedarach (L.) seed extract against armyworm Spodoptera litura (F.) (Lepidoptera: Noctuidae). This study was conducted to evaluate the effectivenes and biological activity of Melia azedarach L. (Meliaceae) seed extract against armyworm, Spodoptera litura F. The first instar larvae were fed extract-treated cotton leaves for 2 days, then were maintained on untreated leaves until the third instar stage. Records were kept in regard to the larvae mortality and developmental time of surviving larvae from first instar to third instar. The result showed that Melia azedarach L. seed extract at consentration of 50 g of seeds/l of water (5%) exhibited moderate insecticidal activity against S. litura larvae (43.33 - 68.33% mortality). Addition of detergen at 0.2% to extract did not increase insecticidal activity of the extract. However, boiling seed extract at consentration of 50 g of seeds/l of water (5%) during 10 until 20 minutes increased insecticidal activity of extract (66.67 - 68.33% mortality). Generally, M. azedarach seed extract treatment did not affect  developmental time of  S. litura larvae.

Analysis of ovipositor extracts of the squash vine borer Melittia cucurbitae showed that a major component in the extracts was (E,Z)-2,13-octadecadien-l-ol acetate along with traces of (Z,Z)-and (Z,E)-isomers. The extracts probably also contained (E,Z)-2,13-octadecadien-l-ol, geometrical isomers of 3,13-octadecadien-l-ol acetate, (Z)-9-hexadecen-l-ol, (Z)-9-hexadecen-l-ol acetate, (Z)-11-hexadecen-l-ol acetate, hexadecan-l-ol acetate, (Z)-13-octadecen-l-ol acetate, and (Z)-13-octadecen-l-ol. Trapping tests with permutations of these compounds showed that a binary mixture of (E,Z)-2,13-octadecadien-l-ol acetate and (Z,Z)-3,13-octadecadien-l-ol acetate (99.7:0.3) was required to effectively cause capture of males. The binary mixture proved to be more effective as a lure for squash vine borer males than (E,Z)-2,13-octadecadien-l-ol acetate alone. Thus, behavioral evidence indicated that a 2,13- plus 3,13-isomeric combination of octadecadien-l-ol acetates quite likely is a natural element in the female sex pheromone of this moth. Physical chemical evidence for the 3,13 isomer in the female extracts was equivocal because its purported occurrence was at a trace level and absolute verification of the compound's structure was not possible.
