摘要

柑橘叶矿工，Phyllocnistis citrella Stainton (Lep。是伊朗柑橘及其相关芜科和观赏植物最具破坏性的害虫之一。幼虫通过形成蛇形取食地雷来破坏叶片，导致产量下降。合成杀虫剂产生的抗药性和毒性问题使得必须寻找更有效和更健康的替代品;因此，生物杀虫剂(即苏云金芽孢杆菌)正成为植物保护的重要组成部分。本研究的目的是评价苏云金芽孢杆菌对柑橘假单胞菌的杀灭效果。用8种浓度的苏云金弧菌对柑桔上的柑橘小孢子虫L3进行喷施，分别于喷施后1、4、7、10 d记录死亡率。结果表明，苏云金芽孢杆菌对柑橘单胞菌的死亡率有显著影响。喷施1、4、7和10 d后，108浓度的苏云金螺旋藻对害虫的死亡率最高，分别为59.8%、68.4、73.6%和77.0%。在101浓度下，死亡率分别为6.5、9.5、39.3%和46.7%。综上所述，在实验室条件下，苏云金芽孢杆菌对柑橘假单胞菌有较好的控制作用。

Bio-control efficiency of Bacillus thuringiensis (Berliner) against the citrus leaf miner, Phyllocnistis citrella Stainton (Lep., Gracillariidae) under laboratory conditions

The citrus leaf miner, Phyllocnistis citrella Stainton (Lep., Gracillariidae), is one of the most destructive pest of citrus and related Rutaceae and ornamental plants in Iran. Larvae damage leaves by creating serpentine feeding mines, which have been lead to reduce yield. Resistance and toxicity problems derived from synthetic insecticides have made it necessary to find more effective and healthier alternatives; therefore, bio-insecticides ( i.e ., Bacillus thuringiensis ) are becoming an important component in plant protection. The aim of the present study was to evaluate the efficiency of B. thuringiensis against P. citrella . Eight B. thuringiensis concentrations were used against P. citrella L3 on orange and mortality was recorded at 1, 4, 7 and 10 days after spraying. The results showed that B. thuringiensis significantly affected mortality of P. citrella . After 1, 4, 7 and 10 days of spraying 108 concentration of B. thuringiensis had significantly caused the highest mortality to the pest with 59.8, 68.4, 73.6 and 77.0%, respectively. Then the mortality percent decreased until it reached 6.5, 9.5, 39.3 and 46.7% at 101 concentration, respectively. In conclusion, the study indicated that B. thuringiensis is effective in controlling P. citrella under laboratory conditions.

期刊介绍： The Journal of Entomological and Acarological Research (JEAR), formerly the Bollettino di Zoologia Agraria e di Bachicoltura of the Institute of Entomology of the Università degli Studi, Milano, was founded in 1928 by Remo Grandori. Thereafter, Minos Martelli and Luciano Süss hold the direction of the Journal until December 2011. In January 2012 the Editor decided for the new open-access on-line version of JEAR. The Journal publishes original research papers concerning Arthopods, but reviews, editorials, technical reports, brief notes, conference proceeding, letters to the Editor, book reviews are also welcome. JEAR has four main areas of interest: -Entomology (systematics; morphology; biology; biotechnology; agriculture, ornamental and forest entomology; applied entomology; integrated pest management; biological control; apiculture and apidology; medical, urban and veterinary entomology; etc.) -Stored product pests (biology; integrated pest management; etc.) -Insect Ecology (behaviour; biodiversity; taxonomy; plant insect interaction and ecosystems; biological control; alien species; etc.) -Acarology (systematics; morphology; biology; parasitology; control; etc.) The publication of manuscripts is subject to the approval of the Section Editor who has knowledge of the field discussed in the manuscript in accordance with the principles of Peer Review; referees will be selected from the Editorial Board or among qualified scientists of the international scientific community. Articles must be written in English and must adhere to the guidelines and details contained in the Instructions to Authors.
