“…Another explanation for the observed whitefly problem might be that the sweet-pepper cultivars grown in Hungary, which have a different breeding history than the cultivars grown in the Netherlands, are better host plants for the greenhouse whitefly than the Dutch cultivars. LASKA et al (1982LASKA et al ( , 1986 provide data indicating that sweet-pepper cultivars from central Europe are less resistant against attack by whiteflies than cultivars from the western hemisphere. They measured whitefly development on 14 sweet-pepper cultivars, one F1 hybrid and one half-wild type.…”

The greenhouse whitefly (Trialeurodes vaporariorum) is a pest insect on sweet pepper (Capsicum annuum) in Hungary, but not in the Netherlands. To examine the underlying mechanism for this difference, whitefly strains from both countries were tested on commonly used Hungarian and Dutch sweet‐pepper cultivars. The developmental rate from egg to adult, the survival rate of adults and the oviposition rate were measured. For all three parameters the Hungarian sweet‐pepper cultivar turned out to be a better host plant for whiteflies than the Dutch cultivar. Also the whitefly strains differed in performance on the two cultivars. The Hungarian whiteflies showed a higher survival from egg to adult and laid more eggs per female on the Hungarian sweet‐pepper cultivar than did the Dutch whiteflies. Both factors ‐ a better adaptation of Hungarian whitefly to sweet pepper and a better host‐plant quality of Hungarian sweet pepper ‐ contribute to explain the observation that whitefly can develop to pest status in Hungary. The results lead to several conclusions: a. sweet‐pepper cultivars show different degrees of resistance to whitefly, increase in resistance of Hungarian cultivars through breeding seems promising, b. whiteflies show different degrees of adaptation to a (relatively poor) host plant, sweet pepper. The experiments were partly financed and took place within the frame‐work of a scientific exchange program between the Hungarian Ministry of Agriculture and Food and the Dutch Ministry of Agriculture and Fisheries. Zusammenfassung Zur Parasit‐Wirt‐Beziehung zwischen Encarsia formosa Gahan (Hym., Aphelinidae) und Trialeurodes vaporariorum (Westwood) (Hom., Aleyrodidae). XXIX. Über die Eignung von zwei Capsium annuum L.‐Sorten als Wirtspflanze von zwei T. vaporariorum‐Stämmen In Ungarn ist Trialeurodes vaporariorum ein Schädling an Capsium annuum, nicht aber in den Niederlanden. Um diesen Unterschied zu untersuchen, wurde jeweils ein Stamm der Weißen Fliege aus beiden Ländern auf der in Ungarn bzw. in den Niederlanden üblichen Paprikasorte angesetzt. Es wurden die Entwicklungsdauer (Ei‐Imago), die Überlebensrate der Adulten und die Eiablagerate bestimmt. Bezüglich aller drei Parameter erwies sich die ungarische Paprikasorte gegenüber der holländischen als die besser geeignete Wirtspflanze. Auch die T. vaporariorum‐Stämme unterschieden sich hinsichtlich ihrer Leistungen auf den beiden Paprikasorten. Der ungarische Stamm hatte im Vergleich zum holländischen auf der ungarischen Paprikasorte eine höhere Überlebensrate, und die Weibchen legten mehr Eier ab. Beide Faktoren ‐ die bessere Adaptation der ungarischen Weißen Fliege und die bessere Eignung des ungarischen Paprikas als Wirtspflanze ‐ können die Beobachtungen erklären, daß die Weiße Fliege in Ungarn ein Paprikaschädling ist. Diese Ergebnisse führen zu folgenden Schlußfolgerungen: a. verschiedene Paprikasorten weisen eine unterschiedliche Resistenz gegenüber der Weißen Fliege auf, eine Resistenzzüchtung scheint erfolgversprechend, b. die Weiße Fliege hat sich u...

“…I hypothesized that this difference is the result of Hungarian whiteflies having been 'pre-conditioned' (Schotzko and Smith, 1991) on other cultivars than Dutch whiteflies. This difference has been shown by Laska et al (1982 and. Their comparative tests of central european and western hemisphere sweet pepper cultivars have shown that central european cultivars are more susceptible to whitefly damage than western cultivars, these two groups of cultivars having different breeding histories.…”

“…These two closely associated mechanisms can be detected and differentiated by measuring parameters such as the reproductive rates and the length of the developmental time of T. vaporariorum. These parameters are used by other authors working with many different horticultural species (Laska et al, 1982;Romanow et al, 1991;Bas et al, 1992), and for ornamental species (Dorsman & van den Vrie, 1987). We also studied the possibility that there might be a prehost effect in T. vaporariorum that led it to choose a particular genotype for its food and for its reproduction and subsequent colonization, as Dorsman & van den Vrie (1987) and van Lenteren & Noldus (1990) observed in other species.…”

One of the yellowing diseases that affects melon (Cucumis melo) crops cultivated under plastic greenhouses in southern Europe is caused by a closterovirus transmitted by the greenhouse whitefly Trialeurodes vaporariorum. A Cucumis melo var. agrestis accession shows a certain level of resistance to that virus. Under free‐choice conditions, the reproduction of T. vaporariorum on this accession was significantly lower than on the susceptible control accession C. melo cv. ‘Bola de Oro’, and this suggests that T. vaporariorum prefers to colonize other accessions before C. melo var. agrestis. Under no‐choice conditions, we observed that T. vaporariorum reproduction on C. melo var. agrestis was less than on the susceptible controls. The results showed the participation of both antixenosis and antibiosis resistance mechanisms against T. vaporariorum in C. melo var. agrestis. It is difficult to cultivate melon completely free from T. vaporariorum and yellowing disease. However, success in breeding commercial melon cultivars which incorporate the antixenosis and antibiosis found in C. melo var. agrestis together with biological or chemical insect control, or a combination of these, would reduce the insect population and, therefore, the melon‐yellowing disease would occur later and in less severe form.
