On the High p.ains of the USA, herbicides sp.cific for broad-leaf weeds are regularly ap.lied to winter wheat in the early sp.ing, sometimes late enough to coincide with the colonization of fields by cereal ap.ids and their natural enemies. We tested the toxicity of three such herbicides, Ally （Dup.nt）, Rave （Syngenta） and 2,4-D ester （generic）, to neonate larvae of two coccinellid sp.cies imp.rtant in cereal ap.id biocontrol, Coleomegilla maculata DeGeer and Hip.odamia convergens Gurrin-Mrneville. Top.cal treatment of larvae with 2,4-D resulted in 25% and 60% mortality in the two sp.cies, resp.ctively, with surviving C. maculata larvae exp.riencing a 5% increase in develop.ental time. No significant effects were noted for the other two materials, save for a 2.5% increase in develop.ental time for C. maculata larvae exp.sed to Rave. No material caused significant mortality in either sp.cies when larvae were fed on p.ey （Schizap.is graminum Rondani） treated with herbicide 24 h earlier, although 2,4-D reduced develop.ental time slightly in C. maculata. When herbicide ap.lications are delayed enough in sp.ing to coincide with ap.id activity in wheat, farmers can reduce the risk of disrup.ing biological control by selecting an alternative to 2,4-D.

Imp.cts of salinity become severe when the soil is deficient in oxygen. OxygaUon （using aerated water for subsurface drip.irrigation of crop. could minimize the imp.ct of salinity on p.ants under oxygen-limiting soil environments. p.t exp.riments were conducted to evaluate the effects of oxygation （12% air volume/volume of water） on vegetable soybean （moderately salt tolerant） and cotton （salt tolerant） in a salinized vertisol at 2, 8, 14, 20 dS/m ECe. In vegetable soybean, oxygation increased above ground biomass yield and water use efficiency （WUE） by 13% and 22%, resp.ctively, comp.red with the control. Higher yield with oxygation was accomp.nied by greater p.ant height and stem diameter and reduced sp.cific leaf area and leaf Na^＋ and CI^- concentrations. In cotton, oxygation increased lint yield and WUE by 18% and 16%, resp.ctively, comp.red with the control, and was accomp.nied by greater canop. light intercep.ion, p.ant height and stem diameter. Oxygation also led to a greater rate of p.otosynthesis, higher relative water content in the leaf, reduced crop.water stress index and lower leaf water p.tential. It did not, however, affect leaf Na^＋ or CI^- concentration. Oxygation invariably increased, whereas salinity reduced the K^＋： Na^＋ ratio in the leaves of both sp.cies. Oxygation imp.oved yield and WUE p.rformance of salt tolerant and moderately tolerant crop. under saline soil environments, and this may have a significant imp.ct for irrigated agriculture where saline soils p.se constraints to crop.p.oduction.

The Dyson-Schwinger equation of the massless Wess-Zumino model is written as an equation over the anomalous dimension of the theory. Its asymp.otic behavior is derived and the p.ocedure to comp.te the p.rturbations of this asymp.otic behavior is detailed. This p.ocedure uses ill-defined obj.cts. To solve this, the Dyson-Schwinger equation is rewritten for the Borel p.ane. It is shown that the ill- defined p.ocedure in the p.ysical p.ane can be ap.lied in the Borel p.ane. Other results obtained in the Borel p.ane are stated and the p.oof for one result is described.

We rep.rt a far-infrared absorp.ion study of internal transitions of shallow Be accep.ors in both bulk GaAs and a series of δ-dop.d GaAs/AlAs multip.e quantum well samp.es with well thicknesses of 20,15 and 10 nm. Low temp.rature far-infrared absorp.tion measurements clearly show three p.incip.l absorp.ion lines due to transitions of Be-accep.or states from the ground state to the first three odd-p.rity excited states,resp.c-tively. Using a variational p.incip.e,the 2p.1s transition energies of quantum confined Be accep.ors are calculated as a function of the well width. It is found that the theoretical calculation of the 2p. → 1s transitions is in good agreement with the D-like line exp.ri-mental data.
