ALAS Flight-Intercept Collections, 2002 Expeditions
Flight-intercept samples were taken by placing ten plastic trays beneath the center pane of a Malaise trap (Figure). Soapy water was placed in the trays. Trays were checked daily. Each day specimens were netted from the trays and accumulated in a bottle of 95% ethanol. Sampling was carried out to parallel the sample accumulating in the collection head of the Malaise trap. One sample comprised two-weeks of accumulated specimens during an expedition. On harvest, bottles were topped off (to prevent sloshing during transport) and immediately transported to the ALAS lab. The ethanol was changed once, and samples were stored in a freezer. Malaise traps 8-17 were used for flight-intercept samples. See under Malaise Traps for specific siting of the traps. There were a total of 30 samples (10 traps x 3 samples per trap). Samples are listed below. For sample 20/TN/16/029, the trays were disturbed by cows on 14 and 15 April and some material was lost on those days.
The data fields, in order, are:
Collection code: a unique code for a collection. The "20" indicates that it is from the 2000m site (Refugio Vara Blanca), the "TN" indicates it is a flight-intercept sample, the following two numbers are the trap number (see map), and the final three-digit number is a serial number beginning with 001 for the first sample and ending with 030 for the last sample.
First collection date: First day of the sample period, in format day-month-year.
Second collection date: Day the sample was harvested.
