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.

Melittia cucurbitae (Harris, 1828) is a very important pest of squash and pumpkins. To date, this lepidopteran had its distribution reported for eastern United States, southeastern Canada, and Mexico. Our study reports for the first time the occurrence of squash vine borer, M. cucurbitae for South America, being the first record to Brazil, in southwest region of Pará state.
