Effects of organic and synthetic fertilizer sources on pest and predatory insects associated with tomatoes

The effects of organic (composted cow manure) and synthetic (NPK) fertilizers on pests (aphids and flea beetles) and predatory arthropods (anthocorids, coccinellids and chrysopids) associated with tomatoes were evaluated in a 2-year randomized complete block field experiment. Our data suggested that the application of either organic or synthetic fertilizers could increase pest populations on tomatoes. However, there were lower populations of aphids on tomatoes grown with the organic fertilizer than on those grown with the synthetic fertilizers in the second year of the experiment, indicating that organic fertilizers may have the potential to reduce pest attacks in the long term. Anthocorid populations were larger on tomato plants with high aphid populations in the synthetic than in the organic fertilizers-treated plots. http://www.phytoparasitica.org posting July 6, 2003.     

湖北省病虫灾成灾面积与受灾面积对应关系的统计分析

考虑到数据扰动项的自相关，利用1978～1995年湖北省病虫灾统计数据，通过Durbin—Watson检验后，基于广义最小二乘法，给出了病虫灾成灾面积与受灾面积的对应关系。

Integrated Biodiversity Management in Paddy Fields: Shift of Paradigm From IPM Toward IBM

The insect fauna in paddy fields is composed of resident, migratory and aquatic species each corresponding to the continuous cropping of rice in the same field, harvesting rice as an annual crop, and originating from still water habitats in wetlands. Although IPM is becoming popular in the control of rice pests, those minor insects and aquatic insects that have no direct economic impact on rice production have received little attention. Consequently, some of them are in danger of extinction requiring conservation. A new concept, Integrated biodiversity management (IBM), is proposed under which IPM and conservation are reconciled and made compatible with each other. As an operational concept in agroecology, premises for implementing IBM are suggested.     

PH3和CO2混合熏蒸储粮害虫的生产性试验报告

为了探索防治抗性害虫的有效途径，于１９９３年９月１３日和１９９４年９月２８日对金华第二粮库的高大型房式仓散装储粮进行了ＰＨ３和ＣＯ２混合熏蒸生产性试验，结果表明，采用他外混合熏蒸机将ＰＨ３与ＣＯ２混合气体通过小孔径白色塑料硬管直接输入仓底，杀虫效果非常理想，对已产生抗性的储粮害虫锈赤扁谷盗，熏杀效果尤为明显。
