THRESHOLD TEMPERATURE AND THERMAL CONSTANT FOR EGG DEVELOPMENT OF NORTHERN CORN ROOTWORM, DIABROTICA LONGICORNIS (COLEOPTERA: CHRYSOMELIDAE)
Published online by Cambridge University Press: 31 May 2012
Extract
The northern corn rootworm, Diabrotica longicornis (Say), is a recent pest of corn in southern Québec (Guibord 1976). Little is known of local quantitative temperature relationships, although such information could have important practical applications in developing a pest management program.
The object of this study was to determine the threshold temperature and thermal constant for egg development and eclosion, and to relate soil and air temperatures to the phenology of egg hatch in the field under Qutbec corn-growing conditions.
