Research Reports: An Adjustable Water-Pan Trap for Simultaneous Sampling of Insects at Different Heights
Abstract
An inexpensive, easy to install, adjustable water-pan trap was developed and used to simultaneously monitor aphids and cicadellids at three different heights in a maize-bean-pumpkin triculture. The trap can be adjusted to any desired height up to 2.2 m. The results suggest that insect activity (as reflected in trap catches) varies with height. In contrast, use of other traps which sample at one height may underestimate insect populations providing a biased or limited representation of their true abundance.Downloads
