Belonocnema kinseyi (agamic)

Belonocnema kinseyi (sexgen)

Belonocnema treatae, new synonym [reversed by Zhang et al]

Hosts: Quercus fusiformis

Locality: TX

Leaf galls.--Leaf galls produced by the bisexual generation [they seem to be attributing the gall to the parent wasp, not the larvae within, unlike other sources] develop following oviposition on buds and on newly unfurled leaves. Galls develop exclusively on the undersurface of leaves and are unilocular, smooth, and pea shaped. At maturity galls are lignified and range from 3 to 7 mm in diameter. Unisexual females emerged from lignified galls from mid-October through early November in both 1996 and 1997. No males have been recorded from the 115 wasps that have emerged from leaf galls in the laboratory.

Root galls.--Root galls induced by unisexual females [they seem to be attributing the gall to the parent wasp, not the larvae within, unlike other sources] grow in irregularly shaped, multilocular clusters on small rootlets just below the soil surface. Clusters appear fleshy and yellow and detach easily from the root surface. Sampled galls were composed of from 1 to 28 chambers and measured 5 to 28 mm in length. Developing root galls have been found in early January and at this stage appear yellow-green in coloration. Mature galls (those from which the bisexual generation has emerged in the laboratory) have been collected in mid-February. In the field, emergence holes in root galls were first observed in mid-March 1997, coincident with the appearance of oviposition scars on leaves of the host plant.
