host instar susceptibility and selection and interspecific competition of three introduced parasitoids of the mealybug paracoccus marginatus (hemiptera: pseudococcidae). | three previously introduced parasitoids (acerophagus papayae noyes and schauff, anagyrus loecki noyes and menezes, and pseudleptomastix mexicana noyes and schauff [hymenoptera: encyrtidae]) of the mealybug paracoccus marginatus williams and granara de willink (hemiptera: pseudococcidae) were studied for their host instar susceptibility and sex ratio, host instar selection, and interspecific competition in the laboratory. all three parasitoids were able to develop in the second instars, third-ins ... | 2010 | 22546446 |
developmental time, longevity, and lifetime fertility of three introduced parasitoids of the mealybug paracoccus marginatus (hemiptera: pseudococcidae). | developmental time, longevity, and lifetime fertility of three previously introduced parasitoids (acerophagus papayae noyes and schauff, anagyrus loecki noyes and menezes, and pseudleptomastix mexicana noyes and schauff) (hymenoptera: encyrtidae) of the mealybug paracoccus marginatus williams and granara de willink (hemiptera: pseudococcidae) were studied in the laboratory to understand the outcome of their recovery in field studies conducted in the united states. the developmental time of both ... | 2012 | 23068176 |
life history of paracoccus marginatus (hemiptera: pseudococcidae) on four host plant species under laboratory conditions. | life history of the mealybug, paracoccus marginatus williams and granara de willink, on three ornamental plants [hibiscus rosa-sinensis l., acalypha wilkesiana (muell.-arg.), and plumeria rubra l.] and one weed species (parthenium hysterophorus l.) was studied under laboratory conditions. mealybugs were able to develop, survive, and reproduce on all four hosts; however, there were differences in the life history parameters. adult females that developed on acalypha and parthenium emerged approxim ... | 2008 | 18559168 |
effect of temperature on the life history of the mealybug paracoccus marginatus (hemiptera: pseudococcidae). | effect of temperature on the life history of the mealybug paracoccus marginatus williams & granara de willink (hemiptera: pseudococcidae) was investigated in the laboratory. p. marginatus was able to develop and complete its life cycle at 18, 20, 25, and 30 +/- 1 degrees c. at 15, 34, and 35 degrees c, the eggs hatched after 27.5, 5.9, and 5.5 d of incubation, respectively, but further development of the first-instar nymphs was arrested. no eggs hatched at 37 degrees c. the developmental time fo ... | 2008 | 19133459 |
