仙人掌蜂蜜治疗犬磷化锌中毒

磷化锌是广泛使用的灭鼠药 ,多用食物配制成毒饵。犬常因误食或吞吃毒死的老鼠而发病。现介绍用仙人掌蜂蜜治疗该病的方法如下。1　病因磷化锌为剧毒 ,通常按 5 %比例混于食物 ,制成毒饵灭鼠 ,犬口服致死剂量为 2 0～40ｍｇ/ｋｇ体重。磷化锌在胃内酸性条件下释放剧毒的磷化氢气体和氯化锌 ,产生强烈的刺激和腐蚀作用。2　症状犬首先表现作呕、呕吐、腹痛、腹泻。呕吐物有蒜臭味 ,在暗处可发磷光。病犬烦燥不安 ,呼吸困难 ,结膜发绀 ,继发肺水肿。后期抽搐并陷于昏迷。3　治疗方法将犬站立保定 ,保定时将两后肢提起 ,使臀高头低 ,用适当粗细…     

浅析家畜磷化锌中毒的综合防制措施

当家畜误食了磷化锌后,在胃酸的作用下,迅速产生磷化氢气体(Zn_3P_2+6HCe_2PH_3+3ZnCe_2)和氯化锌产物。磷化氢有剧毒,被胃肠道吸收入血,通过血液循环,分布在肝、肾、横纹肌等组织器官,引起所在组织细胞发生变性、坏死。同时,可直接损害血管内壁和血细胞,使之发生溶血和形成血栓,最终由于全身广泛性出血,组织缺氧致昏迷而死。氯化锌具有腐蚀性,直接刺激胃粘膜引起急性炎症,表现充血、出血甚至溃疡。本病在临床上与其它中毒病诊治易混淆。对此,笔者在中毒病理学方面作了一些探讨,结合病史和临床症状,进行病理剖检及毒物学检验,为家畜磷化锌中毒的确诊和治疗提供了科学的依据。     

猪肢蹄病防治

<正>猪肢蹄病又称跛行病,是猪四肢和四蹄疾病的总称,是以姿势、步态和站立不正常、支持身体困难为特征的一种普通病,该病成为规模化猪场淘汰种猪的重要原因之一。1致病原因1.1物理因素驱赶种猪时粗暴、猪打架、路面粗劣、跨越沟壑等,使肢蹄受到钝性挫伤,造成肢蹄外伤,轻度的病初肿胀不明显,以后肿胀坚实明显,体温升高,有时疼     

毒签巧治果木蛀干害虫

用毒签可防治多种果木蛀干性害虫，且方法简便易行，虫蛀口愈合快，不影响果木的生长，还有利于虫株长势的恢复，对果木也不会产生药害。1．毒签的制作方法。先将毛竹的节间锯截成长4-5厘米的竹筒，剖开后削成一端尖一端平，直径2-4毫米的小竹签。然后，将192克桃胶、120克磷化锌加适量的水配成溶胶状。     

防治花鼠为害柞蚕

一、花鼠生物学特性及危害花鼠又名五道眉,分布较广。春蚕5～6月、秋蚕7月中旬至9月,花鼠都频繁活动和为害柞蚕。每天清晨开始活动,窜到有蚁蚕的树上,将1～2龄蚁蚕食尽,并把蚁蚕贮存在它的2个颊囊中。颊囊中可贮蚁蚕30～40头,成年田鼠可多达50头。当蚕长至3～4龄时,花鼠将蚕叼到树杈、树桩或大石头上,咬掉头尾,仅食蚕腹部,或咬住蚕头,在石头上摔打十几次,将蚕体内粪便摔出后吃掉。柞蚕做茧后,花鼠爬到柞树上,专为害化成蛹的茧。将茧瞌开一个口子,把蛹吃掉,形成空壳茧;有的咬断茧丝,在树下食害蚕蛹,剩下茧壳;有的把秋茧搬到洞里去。     

福建沿海防护林蛀干害虫防治技术的研究

木麻黄多纹豹蠹蛾、星天牛、相思拟木蠹蛾是福建沿海防护林树种的主要蛀干害虫。白僵菌孢子粉和废糖蜜、红薯粉配制成白僵菌粘膏新剂型,调制过程简单,使用方便,林间涂孔防治多纹豹蠹蛾效果平均达94.4%,相思拟木蠹蛾平均死亡率93.6%,成本费仅为0.128元/公顷。通过对昆虫病原线虫的毒杀力比较,初步说明不同品系的线虫对不同害虫的毒杀力不同,同一品系线虫在不同环境条件下致死率有差异,容易感染线虫的寄主体内也容易繁殖线虫。磷化锌毒签插孔、40%氧化乐果300倍液剂喷干毒杀星天牛初龄幼虫效果分别为84.4%和90.7%。     

东北鼢鼠防治方法的研究

为了摸索鼢鼠的生活规律,找出有效的防治方法。自1978年以来,对该害鼠进行了防治研究。本文着重研究了以磷化锌为主剂的药物毒杀方法。试验结果表明,熟土豆、大葱、植物油拌磷化锌的毒饵杀鼠率最高,5月份杀鼠率比其他月份都高,“风洞”下药方法使杀鼠率提高到82.9/。     

果树蛀干害虫的防治方法

Chemical control of Apriona germari （Hope） larvae with zinc phosphide sticks

Larvae of Apriona germari (Hope), found widely in China, cause serious damage to trees and are difficult to control. Since some biological control methods have not been applied effectively in the field, chemical control methods are used widely. Because of low cost, no poisonous residues and relatively safe application, zinc phosphide sticks have been tested to control the larvae as a matter of urgency. However, there were no criteria about the dosage and use. Given the characteristics of larvae tunnels on triploid Populus tomentosa trees and the one-on-one way of using poison-fumigated sticks, the larvae were treated by three treatments with zinc phosphide sticks. The treatments are as follows: inserting one stick into the first hole of the tunnel from bottom to top (T1), inserting a stick into each of the lowest two holes (T2) and inserting one stick into the first and third hole from bottom to top separately (T3). We cleared the frass around the holes and on the ground before inserting the sticks and blocking every hole with mud for each treatment. After the fourth investigation was carried out, the larvae of CK were still active, and had caused serious damage and emanated fresh frass from old and new holes. Some larvae treated with T1 and T2 were in an intermediate state, but all of the larvae treated with T3 died completely and their old holes had healed. The results show that inserting zinc phosphide sticks (the extent of dispersion of the sticks was 20%) is a feasible method to control A. germari (Hope) larvae in triploid P. tomentosa of pulpwood trees. Because there were no statistically significant differences (p > 0.05) among the three treatments, we recommend that T1 should be used for economic efficacy.     

种子入库验收的几个关键技术要点

入库前,必须做好空仓(包括仓贮用具、包装物、器材等)的消毒灭鼠工作。消毒时,用0．2％的敌敌畏药液喷洒后密封48～72h效果较好;灭鼠时,可用磷化锌或磷化铝按2％的比例与炒谷、食油等混合后诱杀。
