Deposits of crystalline or syrupy honeydews (or mannas) on plants have attracted attention since ancient times. (See Braun, 1938, for a review of early literature.) Essig (1942) points out that the “manna of the Wilderness” of Biblical accounts w

Observations on Citrus Thrips Biology and an Improved Method of Rearing Them in the Laboratory12
Autor: W. H. Ewart, J. B. Beavers
Publikováno v: Journal of Economic Entomology. 64:1124-1127
Biological observations of Scirtothrips citri (Moulton) indicated that an average 21.0 larvae per fertilized female hatched in 12.3 days. An average 46.7 larvae per virgin female hatched in 18.3 days. The time spent in copulation averaged 5.5 min. Ma
