Explanation of Names
Ochyromera ligustri Warner 1961
se. US to NJ (TX-FL-NJ-OK) - Map (2)
; native to SE Asia(1)(3)
Asso. w/ adventive Ligustrum
In Japan, adults have been collected on Japanese privet (Ligustrum japonicum), wax-leaf ligustrum (Ligustrum lucidum), common privet (Ligustrum amurense), but larvae were found only in Japanese privet. (Kojima et al. 1998). In Florida, adults have been reared from Chinese privet (Ligustrum sinense) (Cuda et al. 2005).
Females deposit their eggs in the seed or in the mature fleshy fruits. The young larvae feed inside the fruits during the fall and winter months. Full-grown larvae and pupae appear in late April and early May during the following year. Only one generation per year. (Cuda et al. 2005)
earliest record in our area: NC 1959 (accidentally introduced with host plant). By 1982, it was still only reported from NC to FL (4)
. By 2005, it reached c. TX. (5)
occasionally comes to lights (BG data), but most of the 8 spmns in the UTIC were collected via Malaise trap. (5)
