Traps
There are two types of sticky card traps at each plot which collect flying adult insects. Each trap has 4 replicates.
1) Green lacewing, Chrysoperla plorabunda species (yellow card with AMP lure).
2) Green lacewing, Chrysopa nigricornis species (white card with squalene lure).
Trechnites wasps found on yellow sticky cards are also counted.
The graph below shows the sum of all natural enemies caught on sticky cards. This would include adults of both species of green lacewing, Campylomma bugs, Trechnites wasps, brown lacewings, Deraeocoris bugs, and ladybeetles.
The graph below shows the average number of Trechnites wasps collected from four yellow sticky cards.
The graph below shows the total number of lacewings collected from 8 traps.
