    Description

    The native lace bug, Leptoypha mutica Say (Hemiptera: Tingidae), has demonstrated potential as an insect biological control  agent of invasive Chinese privet (Ligustrum  sinense  Lour).  To  better  evaluate  its  potential to establish on a new host,
    developmental biology on Chinese privet was studied at temperatures of 208C, 248C, 288C, and 328C.  The complete duration of development of L. mutica from egg deposition through five instars on this previously unreported host ranged from 24.4 to 57.1 d. Estimated threshold temperatures and calculated thermal unit requirements for egg development were 11.08C and
    211.9 degree-days (DD); for nymphal development, 9.98C and 326.8 DD; and for complete development, 10.58C and 527.4 DD. Results of this study indicate that L. mutica will oviposit and can develop successfully on Chinese privet over a range of temperatures suggesting the potential for multiple generations to occur in a single season.
