Flower Thrips

Shipments of floral products to Pacific rim markets must meet stringent pest-free requirements. Conventional fumigation methods with methyl bromide will soon become unavailable. Studies show that controlled atmosphere (CA) environments can offer effective insect control. Currently, CA overseas marine shipping is occuring with fresh fruits and vegetables. These shipments use microprocessors to precisely control O2, CO2, temperature and relative humidity. This study is evaluating similar commercial shipments with fresh flowers and foliage under low temperature and low O2 and high CO2 atmospheres. Preliminary results with shipments conducted by TransFresh to Guam indicate that properly maintained CA shipments of 0.5 % O2 kill insects and that flowers in properly maintained atmospheres can withstand 14 days of marine shipment with minimum effect on post-harvest life. Adequate regulation of CA storage during transit seems to be the primary limitation to the expansion of floral markets using this method of shipment.

In 1998–99, outbreaks of Frankliniella occidentalis (Pergrande), western flower thrips (WFT), caused extensive damage to strawberry crops in the Yarra Valley, Victoria. These crops were within 30 km of Toolangi where over 80% of certified strawberry runners for Australia are produced. Commercial growers store runners for various periods of time at temperatures as low as –2°C. Cold temperature disinfestation was evaluated as a potential strategy in a contingency plan to prevent the spread of WFT on strawberry runners. Western flower thrips at various life stages on gerbera flowers (on which they were reared), were placed in small bags, made from the plastic liners used in commercial strawberry runner cartons, together with strawberry runners and exposed to –2°C for periods of 1, 2, 4, or 8 weeks. All WFT died within 4 weeks. Additional experiments were conducted in which WFT, in bags with runners or on gerbera leaf disks in petri dishes, were exposed to –2°C for 3 weeks. Only a few WFT survived these treatments; however, they were moribund. When they were assessed 2 days after completion of the exposure period, all WFT were dead. It was concluded that strawberry runners carrying WFT can be disinfested by exposing WFT to –2°C for 4 weeks and that this should be achievable under commercial conditions.

Insect infestation of fresh produce exported from New Zealand is an ongoing issue for exporters Seventeen lowhazard volatile compounds were screened for their potential as fumigants for controlling adults nymphs and eggs of western flower thrips (WFT) Frankliniella occidentalis (Pergande) WFT infested chrysanthemum flowers were exposed to volatiles in glass jars with circulation fans Higher mortality was achieved for adults than for nymphs/eggs Mortality after the 6 h exposure was greater than after the 2 h exposure Compounds that had good efficacy against WFT included 2propyn1ol diallyl sulphide (the main compound of garlic oils) 2methyl(E)butenal and ethyl acetate Of these 2propyn1ol caused significant phytotoxicity at the concentrations tested The other three were tolerated by the plant material and are worth further investigation
