Abstract
Field studies were conducted at farmer field located at Tando jam to compare the efficiency of horizontal water pantraps of five different colours, to assess their effectiveness in measuring the landing rates of different insect species on mustard crop. Insect species were monitored at weekly interval. Five insect species namely, Aphid, White fly, Beetle and Painted bug were observed. It was observed that the colour of trap and time of sampling greatly influenced the number of insects captured in the different traps. Expect aphid all other insects’ species found in large population at initial stages and later on decreased gradually. The yellow pan traps proved highly effective to capture predominantly more than half of total insects captured in all traps, and it was followed by green and black traps. The white fly was captured more than half of total insect population. Yellow pan traps attracted the greatest number of whitefly, aphid, painted bug and second large number of beetle. The black colored traps attracted painted bug in the highest number.
