OVICIDAL EFFECT IN THE WHITE PINE WEEVIL, PISSODES STROBI (COLEOPTERA: CURCULIONIDAE), OF A SYNTHETIC ANALOGUE OF JUVENILE HORMONE

Abstract

AbstractTopical application of a synthetic juvenile hormone, 1-(4′-ethylphenoxy)-3,7-dimethyl-6,7-epoxy oct-2-ene, to the eggs of the white pine weevil, Pissodes strobi Peck, inhibits embryonic development. Both embryonic and post-embryonic mortality were observed. The construction of simulated ovipositional twigs used in collecting weevil eggs of known age is described. Possible physiological methods of controlling the weevil are discussed.
