<P>PROBLEM TO BE SOLVED: To selectively induce wandering insects that is one of natural enemy insects to a field for exterminating harmful insects existing in the field. <P>SOLUTION: A wandering insect inducing system 1 includes a first inducing light source 2 provided around the field, a second inducing light source 3 provided in the field, and a light-shielding part 21. The light-shielding part 21 forms an area (a second area 7) near the first inducing light source, where the light from the first inducing light source 2 is not irradiated but the light from second inducing light source 3 is irradiated. Some wandering insects 8 that invade the second area 7 among insects induced by the light irradiated from the first inducing light source 2 are selectively induced to the field by the light irradiated from the second inducing light source 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
