Susceptibility of Lantana Cultivars to Orthezia insignis

in HortTechnology

The greenhouse orthezia (Orthezia insignis) is a serious and widespread pest of cultivated lantanas (Lantana sp.) in warmer regions of the world. Forty species and cultivars of lantanas were screened for their relative susceptibility to this insect pest. Results showed that two Florida native lantanas, pineland lantana (L. depressa) and buttonsage (L. involucrata), were highly susceptible to infestation, with trailing lantana (L. montevidensis) and its cultivars and hybrids being somewhat less susceptible. Shrub lantana (L. camara) and its cultivars and hybrids were the least susceptible to greenhouse orthezia infestation, but some of these varieties are rather unattractive as landscape ornamentals and can become serious weeds.
