A new species from the genus Cosmolaelaps, with potential to control western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), were collected litter and remains of plant material on soil different rose greenhouses in The Netherlands. Collected specimens used initiate a laboratory colony. Subsequently, sample mites developmental stages analysed morphologically, by m...

In China, two invasive pests, Bemisia tabaci MEAM1 (Gennadius) and Frankliniella occidentalis (Pergande), often co-occur with the native pest, Aphis gossypii (Glover), on plants of Malvaceae and Cucurbitaceae. All three are preyed on by the native ladybird, Harmonia axyridis (Pallas); however, the native predator might be expected to prefer native prey to the exotic ones due to a shared evoluti...

The western flower thrips, Frankliniella occidentalis (Pergande), is an invasive species and the most economically important pest within the insect order Thysanoptera. F. occidentalis, which is endemic to North America, was initially detected in Kunming in southwestern China in 2000 and since then it has rapidly invaded several other localities in China where it has greatly damaged greenhouse v...

Ultralow oxygen (ULO) treatments with different oxygen levels, treatment times, and temperatures were studied to determine effects on western ower thrips mortality and postharvest quality of iceberg lettuce. Thrips mortality increased with reduced oxygen level and increased treatment ime and temperature. At 0.003% oxygen, over 99.6% mortality rates of thrips were achieved in three ULO treatment...

Frankliniella occidentalis is a pest of horticultural crops, including commercial strawberry (Fragaria x ananassa). Control challenging because certain populations are resistant to insecticides and, in strawberry, now relies on the application biocontrols. However, this approach not always successful if F. overwhelm We investigated whether targeted spectral modifications cladding materials coul...

Western flower thrips (WFT), Frankliniella occidentalis (Pergande), is an important pest of vegetable crops worldwide and has developed resistance to many insecticides. The predatory mites Neoseiulus (=Amblyseius) cucumeris (Oudemans), the entomopathogenic fungus Metarhizium anisopliae (Metsch.), and an insecticide (imidacloprid) were tested for their efficacy to reduce WFT population density a...

Soil physical and chemical properties can affect plant growth and nutrition, which in turn can affect a plantÕs attractiveness and susceptibility to insect herbivores. A further source of variation in these relationships is the spatial scale at which patterns are measured. Both the size of the area being sampled, or scale, and the distance between measurements, or grain, are parameters that aff...
