The invention discloses an insect-killing lamp dual light source based on an electrodeless lamp and light-emitting diodes (LEDs), which relates to tools for trapping and killing injurious insects in agriculture, animal husbandry and forestry and application fields thereof. The insect-killing lamp dual light source comprises an electrodeless lamp light source, an LED light source and power supply circuit boards thereof, wherein ultraviolet light fluorescent powder with the radiation wavelength of 365nm is coated on about two thirds of the inner wall of the uviol glass tube of the electrodelesslamp light source; mercury titanium alloy (Hg-Ti)-containing amalgam is coated on the metal ring of a core column; the LEDs with different light-emitting colors of the LED light source are uniformly and alternately arranged on stripped metal core printed circuit boards (MC-PCBs); and the MC-PCB strips with the LEDs are arranged on each column surface of a regular hexagonal hollow columnar body radiating column. The dual light source which has a plurality of wave crests and the spectral range of between 250 and 650nm, emits light at 360 degrees and is powered by direct current is formed. The dual light source has high flexibility, high reliability, high radiating efficiency and long service life, the injurious insects can be effectively trapped in a full spectrum, and better insect trapping and killing effects can be achieved.
