【Abstract】

<正>Commercially-available Tullgren funnels were shown to be suitable for extracting each of the three larval instars of the carrot fly from soil samples.The skill in using this technique lies in being able to identify the carrot fly larvae,particularly the small 0.5-2 mm long Ist-instar larvae,from all of the other fly larvae present in the samples.The method will be used to quantify the various mortality factors affecting carrot fly larvae.Such information will be incorporated into a model aimed at predicting crop damage at harvest from the numbers of flies caught on yellow sticky traps earlier in the season.
