In order to compare the ability of parasitoid species to oviposit and parasitize the lobate lac scale, the length of time required to penetrate the lobate lac scale with the ovipositor, and the reproductive rates (number of offspring per test cylinder) were compared.
The test cylinder is about 1.5 ft long and 15 mm diam.
We make a mix with plenty of Type III [high-early-strength] cement and accelerators that we were quite comfortable would have the strength we needed 24 hours after the pour." Barnes and Buccini placed a test cylinder in a freezing room overnight and fractured the cylinder in a standard test apparatus the next morning to determine its compressive strength.
The duties of the test operator were to install the nitrogen valve in the test cylinder, place the cylinder in the safety cage and connect the gas line from the gas handling fixture.
