Experiments were conducted in a glasshouse and in the laboratory to determine the environmental and physiological parameters that affect flight behaviour of Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae). The number of whiteflies taking off and

Phloem amino acids in Cucumis melo L. were measured to determine whether changes in nitrogen availability might affect life-history traits and flight activity of Bemisia tabaci Gennadius (Homoptera: Aleyrodidae). During plant development, nineteen of

Bemisia tabaci exhibited their longest flights between 3 and 5 days following adult eclosion. They rarely engaged in flight when they were < 4 hr old and were only capable of short-duration flights after day 7. This difference in flight capacity appe

Temporal, chemical and spatial separation of nitidulid beetles (Coleoptera) were examined with baited traps over two seasons (1989 and 1990) in temperate North America. In both years, Stelidota geminata (Say), Carpophilus lugubris Murray, Glischrochi

Bemisia tabaci, that were flown for varying lengths of time (1 min-2.5 h), exhibited behavioral, morphological, and physiological differences. When whiteflies that were engaging in phototactic orientation in a vertical flight chamber were presented w

The free-flight behaviour of Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae), the sweet potato whitefly, was investigated in a vertical flight chamber. A mercury-vapour lamp presented from above induced a phototactic flight response. Although fli

Host orientation by two nitidulid beetles was compared: Stelidota geminata (Say), which is very broad in its' host range, and Stelidota octomaculata (Say), a species whose feeding is restricted primarily to acorns. In a no-choice assay, both species

Host orientation by Carpophilus hemipterus L. and Carpophilus lugubris Murray (Coleoptera: Nitidulidae) was investigated in a horizontal wind tunnel to ascertain if these species differ in their response to aseptic and fungal-inoculated hosts, and al
