Identification of the molting hormone of the sweet potato (Bemisia tabaci) and greenhouse (Trialeurodes vaporariorum) whitefly.
In order to identify the whitefly molting hormone, whole body extracts of mature 4th instar and newly formed pharate adult Bemisia tabaci (Biotype B) and Trialeurodes vaporariorum were prepared and subjected to reverse phase high performance liquid chromatography (RPHPLC). Ecdysteroid content of fractions was determined by enzymeimmunoassay (EIA). The only detectable ecdysteroids that were pres...
متن کاملHost Plant Effects on Alkaline Phosphatase Activity in the Whiteflies, Bemisia tabaci Biotype B and Trialeurodes vaporariorum
Bemisia tabaci (Gennadius) B-biotype and Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) often coexist on greenhouse-grown vegetable crops in northern China. The recent spread of B. tabaci B-biotype has largely replaced T. vaporariorum, and B-biotype now overlaps with T. vaporariorum where common hosts occur in most invaded areas. The impact of the B-biotype on the agro eco system...
متن کاملCritical Feeding Periods for Last Instar Nymphal and Pharate Adults of the Whiteflies, Trialeurodes vaporariorum and Bemisia tabaci
A critical feeding period is the time after which 50% of a given species of insect can be removed from its food source and complete development by undergoing adult eclosion. The critical feeding period was determined for the greenhouse white fly, Trialeurodes vaporariorum, and the sweet potato whitefly, Bemisia tabaci (Biotype B) (Homptera/Hemiptera: Aleyrodidae). Fourth (last) instar and phara...

متن کاملRapid identification of Trialeurodes vaporariorum, Bemisia tabaci (MEAM1 and MED) and tomato-infecting criniviruses in whiteflies and in tomato leaves by real-time reverse transcription-PCR assay
The whiteflies Bemisia tabaci and Trialeurodes vaporariorum (Hemiptera Aleyrodidae) are harmful pests of vegetable and ornamental crops in many countries. Also, they are vectors of emergent viruses on tomato including the criniviruses (Closteroviridae genus Crinivirus) Tomato chlorosis virus (ToCV) and Tomato infectious chlorosis virus (TICV). Since different vectors are involved in the transmi...
