GO TO ALL:  Bio-Control Cases

 

In Hawaii Cuban laurel thrips attacks Ficus retusa and Ficus benjamina, and their feeding causes young terminal foliage to curl and drop.  Rao et al. (1971) reported that swarming behavior of the thrips has caused a public nuisance.  An anthocorid predator, Montandoniola moraguesi Puton, was introduced from the Philippines in 1964, and became established on Oahu, giving noticeable control of the thrips (Rao et al. 1971).

 

In California Cuban laurel thrips became a prominent pest during the 1960's, causing much the same damage as it did in Hawaii.  Dr. C. A. Fleschner , <PHOTO>of the University of California, Riverside found several species and strains of anthocorid predators in southern Mexico, which were imported and released in California.  Establishment of some predators in California resulted in a marked decrease of the infestation (E. F. Legner, unpub. data).
