Insecticidal effect of halofenozide and methoxyfenozide in different stages of Lymantria dispar, an important cork oak defoliator

Öz

The gypsy moth Lymantria dispar (Lepidoptera, Lymantriidae) is one of the most notorious pests of hardwood trees. It appears in cyclic way and provokes serious defoliations of the cork oak. In Algeria, L. dispar is reported since 1925 and the control of this defoliator consists of chemical insecticides and/or biological control tools. In this project we evaluated halofenozide and methoxyfenozide against larvae of L. dispar. These two molecules are member of a new generation of insect growth regulators that mimic the natural insect moulting hormones or ecdysteroids. Halofenozide is active against Lepidoptera and Coleoptera, while methoxyfenozide is more specific for Lepidoptera. We determined the toxicity and mode of action of these two insecticides by treatment of the larvae of L.dispar. In intoxicated larvae typical morphological aberrations during moulting/ metamorphosis were observed leading to death. In addition, we noted in the surviving adults a strong negative effect on the fecundity and fertility. The results are discussed in relation to the susceptibility of the different stages of L. dispar. Keywords: Lymantria dispar, Algeria, Halofenozide, Methoxyfenozide, Toxicity, Development

 

Evaluation du pouvoir insecticide de deux mimétiques de l’hormone de mue (Halofénozide et Méthoxyfénozide) sur les stades immatures de Lymantria dispar, principal défoliateur du chêne-liège

 

La spongieuse Lymantria dispar (Lepidoptera, Lymantriidae) est l'un des plus importants ravageurs des subéraies. Il apparaît de manière cyclique et provoque de graves défoliations du chêne-liège. En Algérie, L. dispar a été signalé depuis 1925 et la lutte contre ce défoliateur majeur s’appuie essentiellement sur des insecticides chimiques. Dans cette étude, nous avons évalué l’effet insecticide du halofenozide et du methoxyfenozide contre les larves de L. dispar. Ces deux molécules appartiennent à une nouvelle génération de régulateurs de croissance des insectes qui imitent les hormones de mue ou ecdystéroïdes. Le Halofenozide est actif contre les Lépidoptères et les Coléoptères, le méthoxyfénozide est spécifique aux Lépidoptères. Le traitement des larves de L. dispar nous a permis de déterminer la toxicité et le mode d'action de ces deux insecticides et d’examiner son action différée sur la fécondité des adultes issus du traitement des larves. Nous avons calculé aussi les paramètres toxicologiques, comme on a mis en évidence un effet différé sur la fécondité et la fertilité, avec apparition de formes aberrantes de larve et d’adulte.
