As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).

The massive use of chemicals in food production process has adversely affected the aspect of cost, ecology and health in particular. Landscape Integrated Pest Management (LIPM) Program is one of the technology applications targeted to minimize the chemicals. In Indonesia, there were only 6 regencies which applied LIPM, which included Banyumas regency. This study primarily aims at comparing production costs, productivity, revenue, profit and financial feasibility between LIPM and non-LIPM rice farms. The researchers collected primary and secondary data during the investigation. They purposively chose Pliken Village as the research object as it is the only village implementing LIPM. Meanwhile, sample was selected by random sampling methods involving LIPM and non- LIPM farmers with 30 respondents for each. Independent-samples T test was exerted to compare productivity, revenue, cost, profit and financial feasibility. The results indicate that productivity, revenue, profit and financial feasibility farming with LIPM were higher than the non-LIPM farming. Moreover, the production cost in the LIPM farming was lower than the production cost of the non-LIPM farming. The independent T-test pinpoints that the total revenue indicator and profit were significant. In other words, it may become reference to encourage farmers to apply Landscape Integrated Pest Management Program for sustainable agriculture

This paper develops a methodology to calculate the impact of integrated pest management (IPM) on pesticide use, yields, and farm profits. The methodology is applied to the IPM adoption among fresh market tomato producers in eight states. The method is of general applicability. It accounts for self-selectivity and simultaneity, and the pesticide demand and yield equations are theoretically consistent with a profit function. The results support the notion that fresh market tomato growers who adopt IPM for insects and diseases apply significantly less insecticides and fungicides, respectively, than do those who do not adopt IPM; IPM adoption has an insignificant effect on yields and a small effect on profits.
