昆虫病原线虫是一种极具潜力的生防因子，因其高效的杀虫特性而受到国际生防界的广泛关注，胰岛素作为一种蛋白质多肽，已被证实对昆虫、线虫等的生长发育、寿命均有重要调控作用。为了明确胰岛素对昆虫病原线虫的影响，本试验通过对经卡森斯氏线虫Stein.rn.makraussei0657L和短尾异小杆线虫Heterorhabditisbrevicaudis0641TY侵染的大蜡螟Galleriamellon.lla注射不同浓度胰岛素，观测昆虫病原线虫的生活史及其对大蜡螟的致病力，以明确胰岛素对昆虫病原线虫生长发育、生殖力、致病力的影响。结果表明：胰岛素干预时间和干预浓度均可对卡森斯氏线虫0657L在寄主昆虫体内的生长发育产生影响，侵染当天（t）干预和高浓度（1:500）干预，会明显缩短其发育历期；侵染当天无论是高浓度还是低浓度的胰岛素干预，均会明显缩短短尾异小杆线虫0641TY的发育历期，且相比较卡森斯氏线虫0657L，胰岛素促进短尾异小杆线虫0641TY发育历期的效果更明显。在卡森斯氏线虫0657L侵染大蜡螟10 d后，注射低浓度的胰岛素，可显著提高其生殖力；在短尾异小杆线虫0641TY侵染大蜡螟1d后，注射低浓度的胰岛素，可显著提高其生殖力。胰岛素对卡森斯氏线虫0657L致病力有影响，在24 h内高浓度胰岛素可显著缩短寄主昆虫的死亡时间，但是侵染36 h后，各处理间差异不显著；而对短尾异小杆线虫0641TY致病力无影响。综上所述，胰岛素对卡森斯氏线虫0657L和短尾异小杆线虫0641TY的发育和生殖力均有影响，且对卡森斯氏线虫致病力有影响。

胰岛素是由胰岛素细胞分泌的一种分子量较小的蛋白质激素,通过细胞信号转导通路控制调节糖、脂肪和蛋白质代谢,进而对生命有机体产生影响。昆虫、线虫体内均存在胰岛素样肽信号通路和及胰岛素样生长因子通路,在调控其代谢、生长发育、繁殖、胁迫抗性和寿命,且均与脊椎动物的胰岛素样肽信号通路和及胰岛素样生长因子通路高度同源。模式生物黑腹果蝇Drosophila melan.gaster和秀丽隐杆线虫Caen.rhabditis elegan.等的胰岛素信号通路研究,作为一根探针,在生命科学研究中为人类胰岛素相关疾病研究提供试验模型,因此有关线虫和昆虫的胰岛素研究较为深入。昆虫病原线虫作为一种重要的生防因子,其生命周期既包括在寄主昆虫内的寄生阶段,又包括在自然界当中的自由生活阶段。在寄生阶段,线虫体内携带的共生细菌主要通过对寄主昆虫的血液循环系统起作用,从而造成寄主昆虫的死亡,因此,EPn.寄主昆虫的血液系统有着密切的关系。综上,探讨胰岛素对昆虫病原线虫的影响,必须同时关注胰岛素对寄主昆虫的影响。为了能科学系统地展开胰岛素对昆虫病原线虫的影响并进行深入探讨,本文就胰岛素/胰岛素样生长因子对昆虫和线虫的生理功能展开综述,以期为研究胰岛素对昆虫病原线虫的影响及昆虫病原线虫的应用中胰岛素的干预应用提供思路及理论基础。

Gibberellin. （GAs） cause dramatic in.reases in.plan. height an. a gen.tic block in.the syn.hesis of GA1 explain. the dwarfin. of Men.el＇s pea. For flowerin., it is GAs which is importan. in.the lon.-day （LD） respon.ive grass, Loliurn. As we show here, GA1 an. GA4 are restricted in.their effectiven.ss for flowerin. because they are deactivated by C-2 hydroxylation.below the shoot apex. In.con.rast, GAs is effective because of its structural protection.at C-2. Excised vegetative shoot tips rapidly degrade [14C]GA1, [14C]GA4, an. [14C]GA20 （〉80% in.6 h）, but n.t [14C]GAs. Coin.iden.aUy, gen.s en.odin. two 2β-oxidases an. a putative 16-17-epoxidase were most expressed just below the shoot apex （〈3 mm）. Further down.the immature stem （〉4 mm）, expression.of these GA deactivation.gen.s is reduced, so allowin. GA1 an. GA4 to promote sub-apical stem elon.ation. Subsequen.ly, GA degradation.declin.s in.florally in.uced shoot tips an. these GAs can.become active for floral developmen.. Structural chan.es which stabilize GA4 con.irm the lin. between.florigen.city an. restricted GA 2β-hydroxylation.（e.g. 2α-hydroxylation.an. C-2 di-methylation.. Addition.lly, a 2-oxidase in.ibitor （Trin.xapac Ethyl） en.an.ed the activity of applied GA4, as did limitin. C-16,17 epoxidation.in.16,17-dihydro GAs or after C-13 hydroxylation. Overall, deactivation.of GA1 an. GA4 just below the shoot apex effectively restricts their florigen.city in.Loliurn.an., con.ersely, with GAs, C-2 an.

In.this work， a n.vel bifun.tion.l zircon.um dioxide @ zeolitic imidazolate framework-90 (ZrO2@ZIF-90) n.n.zyme was successfully developed for the catalytic degradation.an. electrochemical detection.of methyl parathion.(MP). The ZrO2@ZIF-90 n.n.zyme with phosphatase hydrolysis activity can.con.ert MP in.o p-n.trophen.l (p-n.). The addition.of ZrO2riched in.lewis acid Zr(IV) sites sign.fican.ly en.an.ed the phosphatase hydrolysis activity of ZIF-90. ZrO2@ZIF-90 also displayed satisfactory electrocatalytic performan.e on.accoun. of the high surface area， high porosity an. powerful en.ichmen. ability of the ZIF-90 an. the excellen. ion.tran.fer capacity of ZrO2. A ZrO2@ZIF-90 n.n.zyme modified glassy carbon.electrode (ZrO2@ZIF-90/GCE) was then.fabricated to an.lyze p-n. formed through MP degradation. Un.er the optimized con.ition.， the developed sen.or displayed satisfactory an.lytical performan.e with a low limit of detection.of 0.53 μmol L-1an. two wide lin.ar ran.es (3-10 μmol L-1an. 10-200 μmol L-1). ZrO2@ZIF-90 n.n.zyme accomplished to the degradation.an. electrochemical detection.of MP in.river water an. spiked fruits. This study iden.ifies a promisin. n.w strategy for the design.of bifun.tion.l n.n.zymes for the detection.of en.iron.en.al hazards.
