Abstract

The juvenoids fenoxycarb and methoprene were evaluated for morphogenetic activity on last-instar nymphs of the American bird grasshopper, Schistocerca americana (Drury) (Orthoptera: Acrididae). Topical application of fenoxycarb induced supernumerary nymphs, adultoids and adults with curled wings. Methoprene yielded similar morphogenetic effects although at reduced levels of activity. Of particular interest, however, is the discovery that, in addition to its morphogenetic activity, fenoxycarb causes significant mortality in developing fourth-, fifth- and sixth-instar nymphs.

Résumé

Les juvénoïdes fenoxycarb et methoprene a été étudié pour évaluér l'activité morpho-génetique sur la Schistocerca americana (Drury) (Orthoptera: Acrididae). Le fenoxycarb a provoqué l'apparition de larves surnuméraires, adultoïdes et imagos imparfaites. Le methoprene a produit des perturbations identique en ce qui concerne la métamorphose, mais avec une activité plus bas. Le fenoxycarb s'est révélé capable de provoquer un taux de mortalité très important parmis les chrysalides aux quatriéine, cinquiéme et sixiéme étape de croissance.
