Summary: | The brown lacewing, Micromus tasmaniae, is the most common predator of potato aphids in
South Australia. The probability of capture and prey preference of larval M. tasmaniae were
measured for each instar of Myzus persicae Sulzer (the green peach aphid) at constant 15°e, 20° and
25°e. The probabiUty of capture of M. persicae by larval M. tasmaniae increased after each moult
and declined just before moulting, especially at 15°e. Except for very small and young larvae, the
predator larvae were able to capture efficiently both small and large prey. Young larval predators
showed some preference for smaller prey~ whereas older larvae exhibited little or no preference. The
effectiveness of M. tasmaniae larvae may vary considerably between seasons and climates. |
