From this, we con- variation in environmental conditions. The destruction of the leaves results in considerable loss of yield at harvest. Bento, J. The work lapointe 2010 artificial diet made available under the Creative Commons CC0 public domain dedication. Platygastridaean egg parasitoid of Diaprepes abbreviatus Coleoptera: Average weight was calculated by dividing the total dry weight of survivors by the initial number.
Bt corn, which expresses insecticidal proteins derived from the bacterium Bacillus thuringiensis Berliner, and crop rotation are currently the most effective control measures available for western corn rootworm. For simultaneous optimization of the two different sets of responses the smaller, the better, and the bigger, the better partial desirability d.
Untransformed data are presented Discussion This is the first study that has employed a mixture-amount experimental design to examine the effect of phenolic compounds on the development of a phytophagous insect.
Food Rev Int Amalin, S. June Diabrotica virgifera virgiferaartificial dietdiet toxicity assaysresistance monitoring The western corn rootworm, Diabrotica virgifera virgifera LeConte Coleoptera: Survival was calculated by dividing the number of survivors by the initial number of individuals.
For example, prolonged larval and pupal development times of herbivore insects often lead to prolonged exposure to attack by natural enemies, thus increasing the mortality of individuals that develop slowly Clancy and Price ; Rostas and Hilker Larval survivorship to 10 d ranged from Sotelo and F.
Recent advances include the discovery of an aggregation pheromone and host plant volatiles kairomones and allomones for the Diaprepes weevil, development of mating disruption and attract-and-kill products and application methods for control of citrus leafminer and associated citrus canker disease, and discovery of semiochemicals for use against the Asian citrus psyllid, vector of citrus greening disease.
Journal of Insect Physiology One strategy used in order to achieve the most effective performance is the optimization of operating parameters to create an optimum mass rearing of H.
All relevant data are within the paper.
Duncan, L. 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.
Host plant kairomones for the tropical root weevil Diaprepes abbreviatus. So, It can be concluded that in simultaneous optimization of two different response categories the smaller, the better, and the bigger, the betterthe first level of container size, yeast, oil, chloramphenicol, Nipagin, benomyl, penicillin, agar, and the second level of the other factors have important roles.
Initial research on Diabrotica artificial diet formulation and optimization was directed toward the southern corn rootworm, Diabrotica undecimpunctata howardi Barber Coleoptera: Weathersbee III, A. Feeding response of the green peach aphid Homoptera: Cohen has explained that there are four equally important functional domains of diets: Biocontrol Sci Technol Borchert, and D.
For example, the interactions between phenolic compounds and nutrient levels, and the effects of mixtures on higher tropic levels such as parasitoids, have not been investigated.
Results were analyzed by adult weight Lapointe et al. Lapointe, B.
As a result, the cost-saving ratio is diminished. All diets contained 2. Life history parameters and toxicity results differ greatly across these systems, making comparisons difficult and limiting the extent to which results can be interpreted [ 13 ].
One larva was placed per well using a No.(, 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. After receiving his doctorate from Cornell University inDr. Lapointe worked for the International Center for Tropical Agriculture (CIAT), one of the Consultative Group on International Agricultural Research (CGIAR) centers located near Cali, Colombia until Throughhis research.
