Jahan, M. 1999 Fecundity and survival of brown soft scale, Coccus hesperidum L. (Homoptera: Coccidae) on Nerium oleander L.. Bangladesh Journal of Entomology 9(1-2): 87-92.
Notes: A Tangle-trap sticky barrier method was developed to study the age specific fecundity of Coccus hesperidum L. on Nerium oleander L. in growth room at 26 degree C constant temperature. The scale produced an average of 36.4 crawlers/female/day, during the first week of its oviposition period. A female produced a range of 582-725 crawlers in its one month oviposition period. Crawler production showed a significant linearity with the age of the scale. However, counting the number of crawlers using Tangle-trap method appeared to be an improved way of studying the age specific fecundity of brown soft scale. The survival percentage of settled stage of C. hesperidum was almost double than that of crawlers.
