ABSTRACT:
A transparent cylindrical insect trap provides a bottom entry to a circular truncated entry cone that exits into a cylindrical entrapment chamber, all configured to inhibit insect exit therefrom. The trap top provides a screened orifice to allow volatile olfactory attractant to move upwardly out of the entrapment chamber and entry orifices allow it to move downwardly therefrom. Parts of the trap are colored to provide an optical attractant. The death of insects is hastened in the trap by excessive heat from the `greenhouse` effect and over-exertion caused by the trap design. Both attractants and trap structure cause selective entrapment of wasps.
