P values, regression coefficients RCsand response surface model fitting diagnostic statistics for weight of male and female D. Among the selected factors, penicillin, container size, formaldehyde, chloramphenicol, wheat germ powder, and agar showed significant effect on the mass rearing performance.
The supernatant was again removed, and eggs were triple-rinsed in 10—20 ml of distilled water leaving enough water to allow eggs to lapointe 2010 artificial diet collected in a 1-ml disposable pipette Fisher Scientific, Pittsburg, PA; a.
Effect of soil moisture on development of Diaprepes abbreviatus Coleoptera: Selected Publications Lapointe, S. Therefore, the screening design of 8 ingredients is referred to as a 7-dimensional design space. Root loss associated with larval feeding can also cause plants to lodge, further decreasing yield via unharvested grain Spike and Tollefson, Then, a new ANOVA table was provided, with these six main factors, three levels high, medium and low and, keeping the other factors constant Table 9 However, has not selected for genetic adaptation of D.
The Myers, R. Contour lines indicate the response surface of larval development time. Results Mass rearing by employing Taguchi method In Taguchi method, if the factors and interactions are more than 15, a possible matrix is a thirty two-trial orthogonal array, which is labeled as L32 matrix Growley ; White ; Speidell et al.

Reproductive biology of Fidiobia dominica Hymenoptera: To estimate postemergence weight loss, 10 females and 10 males were caged with water and X1, cellulose; X2, cottonseed meal; X3, wheat germ. Status of biological control by egg parasitoids of Diaprepes abbreviatus Coleoptera: A reduced 3-dimensional design 4 ingredients was used to identify an optimal formulation of the 4 ingredients identified in the screening design [ 25 ].
Department of Agriculture and does not imply its approval to the exclusion of other Lapointe et al. Duncan, L. Environ Entomol Briefly, water and agar were mixed in a ml beaker and microwaved on high until clear.
In Figure 1an increase in the levels of factors such as bean, ascorbate, formaldehyde, distilled water, wheat germ powder, humidity, and temperature resulted in an increase in the response values. Solanum neocardenasii: Patterns and consequences of mating behavior of the Diaprepes root weevil Diaprepes abbreviatus Coleoptera: This factor affects the accuracy of biological characteristics of the insect, e.
However, diet researchers often pay exclusive attention to the nutritional functions of diet components, without considering phagostimulation, textural factors hydrocolloid characteristics, particle size, particle shape, viscosity, and other rheological mattersmeta-nutritional antioxidant functions, anti-nutrients, bioavailability, water activity, antimicrobial potential, over-all stability, microbial deterioration, and numerous other features that must be juggled skillfully to achieve development of fully functional, successful diets Cohen Stelinksi, T.
If p value is lower than 0. Cuticular hydrocarbons on elytra of the Diaprepes root weevil Diaprepes abbreviatus L. Efforts to develop control measures for D. July 31, ; Accepted: Similarly, enhancing the levels of p-coumaric acid, chlorogenic acid or catechin in host fruit, or matching their proportions to nearly Average larval dry weight on Diet D was more than 0.
In order to minimize the number of required tests, fractional factorial experiments were developed. All relevant data are within the paper.
One larva was placed per well using a No.
Sotelo and F. The design was created with examining a normal probability plot of the internally Design-Expert v7.Aug 25, · To do so, the effect of 16 ingredients of an artificial diet including bean, wheat germ powder, Nipagin, ascorbic acid, formaldehyde, oil, agar, distilled water, ascorbate, yeast, chloramphenicol, benomyl, penicillin, temperature, humidity, and container size on some biological characteristics of H.
armigera was evaluated. The selected 16 factors were considered at two levels Cited by: Artificial diet optimized to produce normative adults of Diaprepes abbreviatus (Coleoptera: Curculionidae). Environmental Entomology. An artificial diet for Diaprepes abbreviatus (Coleoptera: Curculionidae) optimized for larval survival - (Peer Reviewed Journal).
(, April) Improved artificial diet for western corn rootworm assays. Oral paper presented at the 26 th International Working Group on Ostrinia and other maize pests. That diet was shown to contain ingredients with little or no effect on the growth or survival of D.
abbreviatus; 3 ingredients (corn starch, cottonseed meal and wheat germ) were identified as principal drivers of larval weight gain and survival (Lapointe et al. ).
