trap patterns
A study of pest-insect trap-layout designs using the TrapGrid computer simulation, compared traditional grid patterns (A and B) with several alternate designs: four crossed lines (C), eight spokes with an untrapped hub (D), two parallel lines (E), four parallel lines (not pictured), five parallel lines (F), six parallel lines (G), and four parallel lines in a modified alignment (H). All designs used 250 traps, indicated by blue diamonds. Establishment positions of pests are indicated with red circles.
