Barrigossi and published by . This book was released on 1997 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: During 1994 to 1996, studies were conducted in western Nebraska, to develop a pest management program for mexican ean beetle (Epilachna varivestis Mulsant) in dry bean (Phaseolus vulgaris L.) based on egg mass sampling. A sampling survey to describe the spatial and probality distributions of egg masses produced a data set of 12,290 egg mass samples from four fields over two years. Semivariograms showed no sign of aggregation, even trough the presence of macroscale trends indicated that mexican bean beetle egg densities may be greater in areas of the field near edges adjacent to beetle overwintering sites. Egg masses had a negative binomial distribution. Life tables were development by following know mexican bean beetle cohorts (egg masses) in three fields in each of two years. High mortality occurred in the egg and first two larval stages. Egg mortality was related to drought-stressed bean plants, because stressed plants turn over their leaves and expose eggs to sunlight. The cumulative mortality ranged from 92,07% to 95,82%, in 1995 and from 60,89% to 75,6% in 1996. No parasitized larvae were observed in the study fields or those held for parasitism tests. Yield-loss relationships for mexican bean beetle on dry bean were determined in a third study. Results from a series of experiments were combined with data from the other two studies to develop economic injury levels (EILs) and economic thresholds (ETs) and a sequential sampling program for mexican bean beetle. The EILs calculated in larvae/tow-m were converted to egg masses/row-m and adjusted to reflect the average survivorship to the adult stage. Because sampling in based on egg masses, growers can make management decisions anda take management actions before significant injury will occur. An interactive spreadsheet was developed to calculate mexican bean beetle EILs, ETs, and sequential sampling plans. The spreadsheet allows users to input economic and other data specific to heir situation. The pest management tools presented in this work should provide a useful for management programs for other insects pests in other systems.

This book was released on 1945 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Mexican bean beetle, Epilachna varivestis Mulsant, has been reported in the southern part of the province of Quebec since the summer of 1943. This insect is known to be a serious pest of beans in the eastern United States and damage to the bean crop amounts to many hundred thousand dollars annually. In the province of Quebec, it is now present only in restricted areas along the international border and damage to the bean crop has already begun. The insect will very likely extend its distribution northward and its importance as a destructive pest of beans will grow accordingly. Studies on the biology of this beetle under our climatic conditions, which studies are essential in the control of any insect, were made during the years 1944 and 1945 and the data obtained are reported in this paper.
