Neohydatothrips burungae was discovered in San Diego County in 2004. It has
previously been reported throughout Central America. In Mexico it is relatively
common on avocado and mango. Little is known about its biology.
Neohydatothrips burungae closely resembles avocado thrips. In comparison with
avocado thrips, N. burungae often has darker brown shading on the thorax, darker
abdominal stripes (brownish rings around the top front of each abdominal
segment), and brown bands occur only on top of its abdomen, not underneath.
However, coloration is variable and may not reliably distinguish these species.
These thrips can be separated by differences in the position and size of setae
(stout hairs) on their thorax and wings. For example, Neohydatothrips
burungae has a continuous or complete row of short stout
hairs on both midveins within its forewings. Avocado thrips has relatively few
hairs along these midveins on its front wings; there are sizable gaps in both
these rows of hairs on avocado thrips. Careful preparation of several specimens
and a good microscope are needed to recognize these characters.
The importance of N. burungae in California is unknown.
No specific monitoring or management methods are recommended for N.
burungae. Whether any management is warranted is unknown.
