Should trapping records or fruit sampling and cutting indicate continued westward movement of A. grandis, APHIS will adopt appropriate measures on imports of cucurbits from Panama.

如果诱捕记录或水果取样将表明南美瓜实蝇继续向西移动，那么美国动植物检疫局在进口巴拿马的瓜类产品时就要采取适当的措施。

An APHIS official visited the outbreak sites to evaluate Panama's surveillance and eradication efforts and was confident that the existing surveillance programs in Panama are sufficient to restrict movement of cucurbits to production areas in western Panama.

一名检疫局官员访问南美瓜实蝇爆发地点，以评估巴拿马的监测和铲除成果，并相信巴拿马现有的监测系统足以限制巴拿马西部地区瓜类的流动。

Based on the trials undertaken in the country and elsewhere foliar application of Kasu-B 3% SL is also reported effective for the control of bacterial soft rot on potato, and kiwifruit bacterial canker and Anthracnose on cucurbits, at a dose of 1500 – 2000 ml/ha.

Dorsalis by salting out, ion exchange chromatography, and gel filtration chromatography. By salting out the egg homogenate, SDS-PAGE analysis revealed that the Vns were mainly precipitated in a 50~70% ammonium sulfate solution. The salted-out proteins were further purified by ion exchange chromatography, and the result showed that Vns were mainly eluted with a 0.3~0.5 M sodium chloride gradient. Finally, the elutes of ion exchange chromatography were refined by running them through gel filtration chromatography to obtain purified Vns. SDS-PAGE separated the 48- and 51-kDa purified Vns, and used them as antigens to raise polyclonal antibodies.

利用硫酸铵盐析法初步分离果实蝇卵中的蛋白质，以SDS-PAGE蛋白质电泳分析得知，卵黄蛋白主要在硫酸铵溶液浓度为50~70%时被沉淀出；盐析沉淀所得之卵黄蛋白，再以离子交换层析法进一步纯化显示，卵黄蛋白主要会在0.3~0.5 M氯化钠的浓度范围间被析出来；再将析出液浓缩后，经凝胶过滤层析法做最后的纯化，即获得纯化之卵黄蛋白。
