CID: Standardizing Leaf Area to Assess Insect Ecology

                                               

Fruit flies cause direct damage to fruits and vegetables through oviposition and larval feeding and restrict movement of commodities across national and international borders. Bait sprays are commonly applied as a means of preventing infestation of fruits and vegetables. For some fruit fly species, such as melon fly, Bactrocera cucurbitae, bait sprays are commonly applied to plants found in crop borders, where adult flies may seek shelter (“roost”).

Establishment of preferred roosting hosts in crop borders may help improve suppression of fruit fly species by providing sites for bait spray applications.

As reported in papers published in 2007 and 2011, Dr. McQuate and his research team assessed the attractiveness of different plant species as roosting hosts for melon fly and oriental fruit fly, B. dorsalis, using the CI-203 Handheld Laser Leaf Area Meter to measure leaf areas of different plant species to permit the standardization of fly catch by leaf area. This standardization was needed because equivalent leaf areas could not readily be presented for all plant species tested.
