These results suggested that inadvertent variation in body size, generated by methods of mosquito production, might strongly affect performance in the olfactometer.
Computer-controlled olfactometer system for studying behavioral responses of ticks to carbon dioxide.
A clean olfactometer was used for every replicate.
Experiments were repeated 14-22 times over at least two days, with the olfactometer turned through 90 between replicates to avoid positional bias.
Y-tube olfactometer bioassays were performed to evaluate the effect of these chemicals on the orientation of conspecific adult females.
The connections of the odour sources to the olfactometer arms were exchanged after testing five parasitoids to remove any asymmetrical bias in the set-up.
Several plants from different plant families that varied in the level of spider mite acceptance were tested in an olfactometer.
Each individual predatory mite was allowed to make a choice in one olfactometer and subsequently in the other olfactometer.
The olfactometer was surrounded by a white paper cylinder (h = 10 cm) in order to eliminate visual stimuli from the surroundings.

All olfactometer experiments for each species were carried out on 3-6 different days.
Throughout the testing period, all olfactometer parts were handled only with rubber gloves, and procedures minimized chances of crosscontamination between volatiles in successive tests.

The trap section of the olfactometer matched the width and height of the flight section and housed the two traps, their supports, and their air supply.

Filtered air at 4 l min-1 was led through each of the jars into the olfactometer.
Fewer mosquitoes were trapped in the olfactometer during the last hour of scotophase (0500-0600 h), consistent with field data, so tests generally were discontinued before this time.
Some aspect of body size may be connected to the ability to respond to stimuli and to behave effectively both in the olfactometer and in nature.
Mosquitoes were left inside the olfactometer for a total of 20 min, after which they were considered to have responded to a test odour if they had entered a trap.
