Method synopsis

Opportunistic collection of adult and larval mosquitoes across elevational gradients using standardized collection techniques. Adults collected during blood-feeding attempts, larvae sampled from diverse aquatic habitats using dippers.

Synthesized from method descriptions across 3 papers using this protocol.

Procedure as described in the canonical source

Steps below were extracted from the paper that introduces this protocol — Mountain mosquitoes of the Gothic, Colorado area (1966), American Midland Naturalist. Implementations in other papers (listed below) may differ.

1. Adult mosquito collection during biting activity
   Adults were collected in ethyl acetate killing-jars as they landed for biting. Collections were made from early morning until evening, with mosquitoes commonly entering buildings to bite or rest after blood meals. Slightly over 1000 biting adults were collected and determined over the study period.
   Quantities: Over 1000 biting adults collected totalDuration: Daily collections from June through August across four field seasons (1957, 1958, 1959, 1962)Conditions: Collections made during mosquito biting activity periods, early morning through evening, in various weather conditions
   Equipment: ethyl acetate killing-jars
2. Larval and pupal collection from aquatic habitats
   Larvae were collected by means of long-handled dippers from various aquatic habitats including snow-melt pools, permanent ponds, stream overflow areas, roadside ditches, and semipermanent marshlands. Approximately 1600 larvae and pupae were collected and determined. Most larvae were preserved for later study while numerous larvae were reared to maturity.
   Quantities: Approximately 1600 larvae and pupae collectedDuration: Collections from June through August, with larvae present from as early as June 14 through late July/early AugustConditions: Collections made from pools ranging from temporary (few inches diameter) to large permanent water bodies, at elevations from 7800 to 12,500 ft
   Equipment: long-handled dippers
