Ascorbic acid, cholesterol, choline chloride, methyl paraben, and sorbic acid were kept constant at the levels in the F diet. Response sur- This highly adaptive insect pest has developed resistance to most management tactics including chemical insecticides Ball and Weekman ; Meinke et al.
Data Availability: Average larval dry weight on Diet D was more than 0. Also, many of the shortcomings of diet development are attributable to a failure to recognize the tremendous difficulty in the problems of diet and rearing system development Cohen Therefore, the effects of these compounds on phytophagous insects may often be dampened by the high nutrient concentrations in artificial diets Lapointe et al.
Significantly more larvae molted when reared on Diet D than on the other diets, and significantly more larvae molted on the WCRMO-1 diet and Pleau et al. If the response i is to be maximized, the quantity d.
The larger the variance of each factor, the stronger the influences on the results. Chrysomelidaeis the most significant pest of maize, Zea mays L. Recently, it has been observed in increasing numbers.
If nutrition similarly affects coleopteran response to toxins, then differences in the artificial diets between individual companies will make direct comparisons between assays problematic, and may not provide an accurate phenotypic picture of the test populations as it relates to susceptibility to toxins.
These include optimization of artificial diets for rearing insects through application of geometric multivariate designs and identification of optimal pheromone blend ratios for trapping and mating disruption.
Frequency histograms Fig. Similarly, chlorogenic acid or p-coumaric acid did not significantly reduce larval weight but the opposite was observed when chlorogenic and p-coumaric acids were presented as a mixture.
Beavers, J. Shapiro, and K. Niedz and D. Lapoinite et al. Use of landscape fabric to manage Diaprepes root weevil in citrus groves. Stuart and S. Extended Bioassays Bioassays originally aimed at adult emergence were similar to larval diet bioassays, except that larvae were transferred to a new diet plate every 10 d initially and every 7 d as larvae grew larger.
In our work, we chose weights equal to 1 for all six responses. Derringer's desirability function was used for simultaneous optimization of mass rearing of tobacco budworm, H.

The laboratory diet contains 4–12 times the amount of protein observed in natural hosts, such as grapefruit or mango, and the protein: carbohydrate ratio of artificial diet (1: ), grapefruit (1: ) and mango (1: ) are quite different (Cicero ).Cited by: 6.
