Abstract

First instar larvae of five spring Aedes spp. mosquitoes survived for at least 25 days beneath moderately thick ice (4.5 cm) in an open field habitat. While survival in the open field was in excess of 85%, larvae inhabiting a nearby deciduous woodland pool suffered 100% mortality within 25 days. Dissolved oxygen levels in the woodland pool fell drastically over the period of ice-cover indicating a trend toward an anaerobic condition which likely contributed to larval mortality.

Résumé

Les larves de premier stade de 5 espèces printannières d'Aedes ont survécu pendant au moins 25 jours sous une couche de glace d'épaisseur moyenne (4.5 cm), dans un habitat situé en plein champ. Alors que la survie était supérieure à 85%, des larves vivant dans un étang de boisé décidu situé à proximité ont subi 100% de mortalité après 25 jours. Les concentrations en oxygène dissout dans l'étang situé dans le boisé ont chuté de façon très marquée durant la période de recouvrement par le glace, indiquant une tendance vers l'anaérobie laquelle a sans doute contribué à la mortalité larvaire.
