Larval density was not precisely controlled, and with this procedure ranged between 100 and 200 individuals per vial.
Many of these doomed larvae had crawled onto the sides of the vial rather than remaining on the food.
Helminths were removed and placed in vials containing fixing agents and were then processed, identified, and counted.
Offspring were collected and aged for 1 day in vials.
The sealed vials were time/date labeled and stored in a ziplocked bag in the family's refrigerator until collection was completed.
The vials were continuously monitored from the time the painted male was introduced through to hour 14.
For oviposition, a spoon with 2 ml of medium and coated with live yeast paste was placed in each vial.
The cages consisted of 7 shell vials, whose bottoms had been sawed off, glued together in a circle with the seventh vial in the middle.
