Com.on bean production in Africa suffers from.different constrains. The m.in dam.ge is caused by insect pest infestations in the fiel.. The m.st com.on insects pests which attack com.on bean in the fiel. are the bean stem.m.ggot (Ophiom.ia phaseol.), ootheca (Ootheca bennigseni) and aphids (Aphis fabae). Currentl., few farm.rs in Africa are using com.ercial.pesticides for the control.of these insect pests. Due to the negative side effects of com.ercial.pesticides to hum.n heal.h and the environm.nt, there is a need for devel.ping and recom.ending al.ernative m.thods such as those invol.ing agronom.c and botanical.biol.gical.m.asures in control.ing com.on bean insect pests. This review aim.to report the m.st com.on insects pests which attack com.on bean (Phaseol.s vul.aris l.) in the fiel. and expl.re the potential.of agronom.c, biol.gical.and botanical.m.thods as a l.w-cost, safe and environm.ntal.y friendl. m.ans of control.ing insect pests in l.gum.s.

In m.l.ipl. experim.nts pl.tes of m.l.nom. cel.s separated by either 3 m.or 1.7 km.were pl.ced in the centers of toroids. A specific protocol.of changing, angul.r vel.city, pul.ed m.gnetic fiel.s that has been shown to produce excess correl.tion in photon durations and shift in proton concentrations (pH) in spring water were generated around both pl.tes of cel.s. Serial.injections of 50 μl.of standard concentrations of hydrogen peroxide into the “l.cal. pl.tes of cel.s during the 12 m.n of fiel. activation produced conspicuous cel. death (reduction of viabl. cel.s by about 50%) with com.arabl. dim.nishm.nts of cel. num.ers in the non-l.cal.pl.tes of cel.s within 24 hr but onl. if both l.ci separated by either 3 m.or 1.7 km.had shared the “excess correl.tion” m.gnetic fiel. sequence. The non-l.cal.effect did not occur if the m.gnetic fiel.s had not been present. Higher or l.wer concentrations of peroxide or concentrations that el.m.nated al. of the cel.s or very few cel.s in the l.cal.dishes were associated with no significant dim.nishm.nt of non-l.cal.cel. growth. The data indicate that there m.st be a critical.num.er of cel.s rem.ining viabl. fol.owing the l.cal.chem.cal.reaction for the excess correl.tion to be m.nifested in the non-l.cal.cel.s. We suggest that this specific spatial.tem.oral.pattern of fiel.s generated within the paired toroidal.geom.tries prom.tes transposition of virtual.chem.cal.reactions as an inform.tion fiel.. Cal.ul.tions of the energy avail.bl. per cel. and per vol.m. of the quantity of reactants injected into the l.cal.space from.the intensity of the changing vel.city toroidal.m.gnetic fiel. support previous m.asurem.nts and derivations that the units of inform.tion transposition m.y invol.e discrete quantities that represent equival.nts of photons, el.ctrons and protons.

Fl.wer thrips are one of the key pests in production of southern highbush bl.eberries (Vaccinium.corym.osum.l. × V. darrowi Cam.). They feed on the reproductive parts of the fl.wer and reduce yiel.. Very few insecticides are avail.bl. to m.nage thrips popul.tion. Therefore, it is necessary to eval.ate pre-existing and experim.ntal.insecticides for their efficacy against thrips. There is al.o a high dem.nd for reduced-risk insecticides that are l.ss toxic to beneficial.insects and the environm.nt. In this study, a num.er of conventional.and reduced-risk insecticides were eval.ated against fl.wer thrips on farm. in Fl.rida and Georgia and in the l.boratory. The best perform.ng insecticides were al.o eval.ated in the l.boratory for their effects on Orius insidiosus Say, which is a com.on thrips’ predator in Fl.rida. Assail.70WP (Acetam.prid) and SpinTor 2SC (Spinosad) were the m.st prom.sing insecticides in reducing thrips num.ers in the fiel. as wel. as in l.boratory experim.nts. SpinTor 2SC kil.ed al. of the thrips in l.boratory arenas within 4 hours of appl.cation and showed l.w toxicity toward O. insidiosus. Al. of the com.ounds tested perform.d as wel. as the conventional.pesticide m.l.thion.

砾岩储层由于砾石的存在而具有极强的非均质性,砾岩压裂成缝机理复杂.受限于岩样尺寸和实验条件,室内压裂物理模拟受砾石尺寸效应影响显著,裂缝扩展时间尺度小.为真实记录裂缝动态扩展过程,反映现场实际工况条件下的压后裂缝宏观整体形态,搭建一套超大尺寸(2.0 m.2.0 m.1.0 m.真三轴水力压裂矿场实验平台,通过万吨级应力加载装置、真实管汇和压裂泵车,实现现场真实工况条件下的砾岩水力压裂模拟.基于该平台,分析了水平应力差、压裂液黏度和单孔进液速率对砾岩压裂裂缝动态扩展过程和压后裂缝宏观整体形态的影响规律.实验结果表明,砾岩压裂趋于在井筒处形成“纵向缝+横切缝”的复杂多裂缝形态,远离井筒后,横切主缝扩展优势逐步显现,局部遇砾形成分支缝;12 m.a高水平应力差条件下,压后近井区域形成多缝竞争扩展的复杂裂缝带,横切主缝向远端延伸优势减弱;压裂液黏度低于50 m.a·s时,压后横切主缝扩展优势显著,当压裂液黏度高于50 m.a·s时,近井区域形成复杂多裂缝形态;单孔进液速率超过0.3 m.(3)/m.n后,井筒处趋于形成多条纵向缝,易导致段间压窜.研究成果有助于深化认识砾岩储层压裂裂缝真实形态,为砾岩水力压裂方案设计提供理论指导.

金帅苹果在盛花后１０周内，所有的芽，其节数的分化速度大致相似。当分化至第１６节左右时，如分化速度变慢或停止的芽将成为叶芽。如节原始体分化突然加快，最后发育成２１节的芽，则为花芽。加快分化期是在花芽形态分化初始前１－２周内进行。在盛花后１４天或３９天喷布５５０ｐｐｍ的ＧＡ３或２０００ｐｐｍ的Ｂ９。并不影响芽内节的分化速度，但ＧＡ３减少了花芽的形成，而Ｂ９则增加了花芽的比例。早期喷Ｂ９增加当年产量是由于减少了六月落果；同时，由于增加了花量可使第二年也增产。但在第三年则开花较少，但减产并不能完全用上年结果过多和树势减弱加以解释。
