Abstract The sugarcane borer, Diatraea saccharalis (F.), is the primary pest of sugarcane, Saccharum spp., in Louisiana. Recent evidence suggests an integrated pest management (IPM) program has reduced the pest’s impact, but the success of this program has not been assessed across the industry. The level of D. saccharalis injury present at harvest was recorded from 388 billet samples from five sugar mills from 2017 to 2019. These results were used to estimate direct and indirect revenue losses from D. saccharalis on the Louisiana sugarcane industry. Insecticide use records were used to estimate control costs and determine total economic impact. The mean percentage of bored internodes was 1.1, 0.3, and 1.7% for 2017, 2018, and 2019, respectively. Direct losses from reduced sugar yield averaged US$4.6 million across years. Indirect losses across years accounted for US$3.0 million and $463,000 for insecticidal control costs and reduced milling efficiency, respectively. The total economic impact of D. saccharalis averaged $8.0 million annually during the three-year study period. This study demonstrates the efficacy of pest management implementation in reducing D. saccharalis injury and highlights the value of IPM. Our findings provide new support for the emergence of D. saccharalis management in the Louisiana sugarcane industry as a modern IPM success story.

Populations of onion thrips Thrips tabaci and their natural enemies were monitored in small field plots of onions to which standard insecticide (methamidophos endosulfan and chlorpyrophos) selective insecticide (imidacloprid and spinosad) organic (YR015) insecticide or no insecticide treatments were applied The mean number of thrips per plant was kept below 12 in the standard and selective treatments The numbers of thrips in the organic and no insecticide treatments were comparable reaching over 60 thrips per plant This resulted in increased plant damage and shorter leaves High rainfall in 200102 coincided with a reduction in thrips numbers in untreated plots which peaked at 70 thrips per plant compared with nearly 500 thrips per plant in the drier 200001 season Natural enemies observed in the unsprayed and organic treatments included Ceranisius menes Aeolothrips fasciatum Buchananiella whitei syphids and entomogenous fungi None of these natural enemies increased sufficiently to provide effective thrips control No natural enemies were found in the standard or selective insecticide treated plots

Abstract Achieving high quality propagative material is difficult today due to the limited number of pesticides recommended for use. Simultaneously, EU regulations on Integrated Pest Management (IPM) in forest nurseries came into a force, requiring a search for alternative plant protection methods that are safe for humans, animals and the environment. In this paper, we present the possibilities of using bio-fungicides against diseases in forest nurseries, their mechanisms of action, as well as the direction of their development (according to IPM rules). We reviewed the results achieved by different research teams presenting the possibilities and trends in combatting Oomycetes and Fusarium spp. pathogens currently having the most important economic impact.

The Past

Pesticide applications directed against the orangestriped oakworm declined by over 80% the first year after implementation of an aesthetic injury threshold into an Integrated Pest Management program. After a moderate resurgence 2 years later, pesticide use further declined with no pesticides applied against this pest in the past 7 years. Cost and pesticide use decreased from $6,795 and 55,000 L (14,300 gal) in 1986 to $877 and 7,800 L (2,028 gal) in 1988 and no cost since 1999.

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).
