Introduction

1. Leafminer Liriomyza trifolii is a damaging pest
   
   1. Low damage crops helped by insecticide for leafminer control (Cox et al. 1995)
   2. Overuse of insecticides cause resistance in L. trifolli. (Leibee 1981, Parrella and Keil 1984)
   3. Cyromazine and abamectin both successful for leafminer control (Trigard)
   4. One case of L. trifolli being resistant to Cyromazine in 1990 Florida (G. L. Leibee and J.S.F., unpublished data)
   5. Unstable resistance and no cross resistance of cyromazine and abamectin
   6. 1991 survey said cyromazine resistance only affects celery in one location (G. L. Leibee and J.S.F., unpublished data)
   7. No published reports of abamectin and cyromazine resistance on leafminers
2. Florida Fruit and Vegetable Association gathers scientists, commercial growers, and the agricultural chemical industry to try to make a leafminer resistance program
