“…Values of r m of F. occidentalis at 25 C as reported in literature are: 0.17 day ,1 on susceptible cucumber cv. Corona (van Rijn et al, 1995), 0.157 day ,1 on a susceptible cotton variety (Trichilo & Leigh, 1988), 0.14 day ,1 on bean (Brødsgaard, 1991;Gerin et al, 1994), 0.171 day ,1 on chrysanthemum (Robb, 1989), 0.127 day ,1 on petunia (Wijkamp, 1995) and 0.02 day ,1 on peanut (Lowry et al, 1992). In the present study negative values for r r were found on the most resistant cucumber accessions, especially for population NZ.…”

Key words: Frankliniella occidentalis, Cucumis sativus, biotype, host plant resistance, life history, population growth rate AbstractBiotypic variation is of major concern in breeding for host plant resistance to insects. The existence or development of aggressive biotypes can lead to a rapid break-down of host plant resistance. Therefore the study of biotypic variation should be included in breeding programs for resistance to insects. In the present study we measured the reproduction of randomly collected females of ten different populations of the insect herbivore Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) on one susceptible and two resistant cucumber (Cucumis sativus L.) accessions. Significant differences between thrips populations were observed on all three cucumber accessions. None of the populations had a significantly higher reproduction than the Dutch reference population NL1. For three populations, the Dutch population NL1, a population from New Zealand (NZ), and an Italian population (IT), partial life history parameters, such as reproduction rate, developmental time and survival were determined and the relative rate of increase r r was calculated. On all three cucumber accessions the r r -value of population NZ was lower than of populations NL1 and IT. It is concluded that there is biotypic variation in F. occidentalis with regard to performance on cucumber plants with different levels of resistance. Reproduction is a good criterion for differentiating biotypes of F. occidentalis on cucumber.

“…This is especially the case with second-instar thrips, as the subsequent stage (the prepupa) does not remain on the leaf and begin the acquisition process anew. Gerin et al (1994) reported that the duration of the second-instar of western Xower thrips reared on beans at 25°C is ca. 3 days (73.4 h).…”

“…Previous life‐history studies have investigated the development and reproduction of F. occidentalis on many different plants, including bean (Brødsgaard, 1994; Gerin et al., 1994), chrysanthemum (Robb & Parrella, 1991), cotton (Trichilo & Leigh, 1988), cucumber (Gaum et al., 1994; van Rijn et al., 1995; de Kogel et al., 1997; Hulshof et al., 2003), and peanut (Lowry et al., 1992). In these experiments, thrips were tested either on whole plants (on which they may have fed on any plant part) or on leaves only.…”

Experiments were performed to investigate the influence of apple pollen, plant diet, and relative humidity on the individual life‐history traits and on the population growth of the western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae). In experiments with individual thrips, availability of bean pods plus a mixture of apple pollen and lycopodium shortened larval development time, and hence time from egg to adult, compared to bean pods alone. Similarly, the total number of eggs laid and the mean number of eggs laid per female per day were greater in the presence of pollen plus bean pods than on bean pods alone. Diet did not affect survival or length of the pre‐oviposition and oviposition periods. A diet including bean pods plus pollen shortened the generation time and population‐doubling time, and increased the net reproductive rate and the intrinsic rate of increase, compared to bean pods alone. In experiments on populations, growth was measured with different amounts of pollen on bean pods under two relative humidities, ca. 38% and 66%, and separately on two bean substrates, pods or leaves, at ca. 45% r.h. The presence or amount of pollen had no effect on population growth regardless of the other variables. Greater population growth occurred under the higher relative humidity regardless of substrate. Population growth was greater on bean pods than on bean leaves. Despite reports on the nutritional benefit of pollen for F. occidentalis, this benefit may be affected by pollen type, host plant, and other factors. In situations in which pollen has little influence on the growth of F. occidentalis populations, pollen that benefits a thrips predator could be used in an integrated management plan for controlling thrips.
