Factors Influencing Population Growth Of Tribolium Brevicornis In The Laboratory, Amin Gulla
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
To determine the effect of the factors of the environment (temperature, relative humidity, and food) on the population growth of Tribolium brevicornis, different levels of temperatures from 17.5°C - 37.5°C were used. Effect of these IeveIs of temperatures was tested upon both pre-embryonic and post-embryonic development. No hatching occurred at 17.5°C, but the threshold temperature (the minimum temperature for the development) was just before 17.5°C. The optimum temperature for the embryonic development was found to be between 32.5°C - 35°C.
With the use of the saturated salt solution according to Buxton (1931) and Buxton and Melanby (1934), certain humidity …

A Check-List And Keys To The Primitive Sub-Families Of Cerambycidae Of Illinois, Michael Jon Corn
Masters Theses
The long-horned beetles, family Cerambycidae, form a large, colorful, often-collected and well-known group. However, the drab, more primitive subfamilies, Parandrinae, Prioninae, Aseminae, and Spondylinae, are much less well-known although they often appear in collections.
In this paper, the author has attempted to list those species of primitive cerambycids which occur or are likely to occur within the State of Illinois. Keys, illustrations, descriptions, and distribution maps have been developed to aid in identification. The list and keys should be applicable to any midwestern state with the addition or deletion of a few species.
