摘要

以使用生物农药为基础的虫害综合防治已得到广泛应用。实验生物测定对于在生态毒理学层面评估生物农药的生物安全性至关重要。在本研究中，我们调查了新型苏云金芽孢杆菌库氏亚种（Btk）配制型生物农药 BLB1 和 Lip 对两种水生非目标生物（即水蚤大型水蚤和生物发光细菌 Aliivibrio fischeri）的影响。急性毒性研究是以 Delfin® 作为参考生物产品和以乳糖为基础的 Blank 配方进行比较的，结果表明在 1 克/升以下未观察到明显的毒性。我们的研究结果表明，BLB1 和 Lip 配方的新型生物制品的毒性远远低于 Delfin® 参考生物制品。

Effects of New Btk-Based Formulations BLB1 and Lip on Aquatic Non-Target Organisms.

Integrated pest management based on the use of biopesticides is largely applied. Experimental bioassays are critical to assess biopesticide biosafety at the ecotoxicological level. In this study, we investigated the effects of the new Bacillus thuringiensis subsp. kurstaki (Btk)-formulated-based biopesticides BLB1 and Lip, efficiently tested in field assays (IPM-4-CITRUS EC project no. 734921) on two aquatic non-target organisms, precisely the water flea Daphnia magna and the bioluminescent bacteria Aliivibrio fischeri. Acute toxicity studies, carried out in a comparative manner with Delfin^® as the reference bioproduct and the lactose-based Blank formulation, show that no significant toxicity was observed up to 1 g/L. Our results indicated that BLB1- and Lip-formulated new bioproducts are far less toxic than the Delfin^® reference bioproduct.

期刊介绍： Biology (ISSN 2079-7737) is an international, peer-reviewed, quick-refereeing open access journal of Biological Science published by MDPI online. It publishes reviews, research papers and communications in all areas of biology and at the interface of related disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
