  Strains Comn 1 and No.1800 of Staphylococcus aureus have been first compared during serological tests for detecting tomato viruses by virobacterial agglutination test (VBA). The results showed that the strain No. 1800’s sensitivities were 2～ 10 times higher than strain Comn 1’s. The former enabled the detection of ToMV,CMV and PVX viruses at a concentration of 3.4 ～ 13.0 ng / mL and the maximum leaf sap dilution of 1/ 1000 ～1/ 100000, which were almost equal to them by PAS-ELISA. ...

  The toxicity of several organophosphorus insecticides chlorpyrifos,dimethoate,malathion and dichlorvos to the larvae and female adult of Liriomyza sativae was determined. The adult eating and egg laying repellent in choice and no choice assays were also investigated. The results indicated that the 1st,2nd and 3rd instar larvae and female adult of leafminer were very sensitive to chlorpyrifos,the LC 50 of the 1st,2nd and 3rd instar larvae was 0.0682,0.1216 and 0.1423 g/L respectively. For female a...

  The prematurity and yield of six varieties of L. cylindrica were compared in fields. The results showed that ‘Jingmenzhong’ and ‘Hangzhou Rousigua’ with low node position of the 1st female flower,high early yield and total yield,were suitable for purpose of prematurity breeding,so was ‘Baiyushang’ with higher early yield and medium total yield. ‘Changsigua’ with strong growth and high total yield was useful for breeding also. But ‘Xiaoshaozhong’ ‘Dashaozhong’ and ‘Bangchuigua’ could not be directly used...
