Plant tissue weight, and levels of major chemical elements, were determined for leaves attacked by three species of gall forming Cecidomyiidae, and comparable tissue from normal leaves. Weight of leaves was directly related to the number of galls cau

Bombus griseocollis (DeGreer) was found to be the most common visitor to flowers of Lycopersicon peruvianum at Fort Collins (Larimer County) Colorado. Five other species of Bombus were less frequently observed on the flowers along with an occasional

Starch, reducing, and non-reducing sugar levels were determined for three coniferous insect galls and compared with levels in normal tissue. Reducing sugar levels in tissue from two galls caused by Cecidomyiidae were significantly higher than those f

Janetiella coloradensis Felt (Diptera: Cecidomyiidae) causes severe needle shortening on pinyon, Pinus edulis Engelm. Infested needles are about one-third normal length, with swollen bases and enlarged fascicle sheaths. Needle drop occurs after the n

Three species of Boxwood, Buxus bullata, B. nana and B. sempervirens were exposed to the Boxwood gall midge, Monarthropalpus buxi (Lab.) at three time periods in an attempt to artificially infest the plants and determine differences in plant species

The pine shoot beetle, Tomicus piniperda (L.), is an exotic pest that has become established in North America. Discovered in Ohio in 1992, it has since been found in at least 13 states and parts of Canada. The beetle can cause significant growth loss

Pre-B cells can express secretory mu (mu(s))- as well as membrane mu (mu(m))-chains. We evaluated the ability of mu(s)-chains to associate with surrogate light chains and assemble into a pre-B cell receptor (BCR) complex in pre-B cells, and explored

Galls caused by seven species of European cecidomyiids were found on leaves of Populus tremula, native to Europe, on P. tremuloides, native to North America, and on leaves of their hybrids planted in southern Bohemia. Some galls on hybrids had unusua

The predominant functions of secreted IgM, complement fixation and transcytosis across epithelial barriers via the poly(Ig) receptor, are properties of IgM polymers; thus, the mechanisms that regulate oligomerization are critical to immune function.
