“…Since the insect was introduced into the United States more than 70 years ago, it has rapidly become one of the most important insect pests of com because of its ability to adapt to the new environment and to attack to a large number of plant hosts (Beck 1989, Hudon et al 1989, Ellsworth and Bradley, Jr. 1992. From the early years of ECB research, chemical insecticides have played a major role in crop protection because of the high economic value of field com, popcorn, and sweet com for the fi'esh market (Thompson and White 1977, Grafius et al 1990, Weissling et al 1992, Hutchison 1993, Rinkleff et al 1995. But with increased use of synthetic insecticides on com fields, several potentially adverse effects can occur, such as water and soil contamination, insect resistance, and toxicity to nontarget species.…”

This manuscript has been reproduced from the microfilm master. TJMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter fiice, while others may be from any type of computer printer.The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely aflfect reproduction.In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book.

Sixteen natural monoterpenoids and 6 synthetic derivatives were selected for study of larvicidal activity and growth inhibitory effect against the European corn borer, Ostrinia nubilalis (Hübner). For this study, 2 different dietary exposure bioassays were used: compounds applied on the diet surface (on-diet), and compounds incorporated into the diet (in-diet). Most of the monoterpenoid compounds showed some degree of larvicidal activity in both bioassay procedures after a 6-d exposure period. Among the monoterpenoids, pulegone was the most active. Larvicidal toxicities were significantly enhanced for the structurally modified compounds; monoterpenoid derivatives MTEE-25 (2-fluoroethyl thymyl ether) and MTEE-P (propargyl citronellate) were most toxic to borer larvae. When reared on diet containing the monoterpenoids or their derivatives, changes in developmental parameters and pupal weights of the European corn borer also were noted when they were fed several of the compounds. Some larvae reared on treated diet with higher concentrations of the test compounds died before pupating. In general, growth and development of the European corn borer were affected by monoterpenoid compounds, and some compounds such as lmenthol, pulegone, MTEE-25, and MTEE-P acted as insect growth inhibitors.
