A Japanese race of the parasite Pediobius foveolatus (Crawford), with its origin in Okayama Prefecture, Honshu, was released in 1980 against the Mexican bean beetle, Epilachna varivestis Mulsant, at 43 sites (31 in Indiana) in eight U.S. midwestern states to test for parasite overwintering. Post-release reproduction was confirmed at 19 sites in six states. However, in 1981, there was no evidence of successful parasite overwintering. This was attributed to the unavailability of suitable host… Expand
Natural History, Ecology, and Management of the Mexican Bean Beetle (Coleoptera: Coccinellidae) in the United States
TLDR
The general biology of Mexican bean beetle is reviewed, management options to mitigate crop damage, and its historical timeline as a pest in the United States are reviewed. Expand
Organic management of Mexican bean beetle (Epilachna varivestis Mulsant) in snap bean (Phaseolus vulgaris L.)
TLDR
Tolerance to MBB infestation was not observed in any of the varieties studied, and the use of row cover and staggering of planting date proved to be unsuccessful, increasing bean yield, however MBB larval, pupal, and adult populations were found to be different when growing conditions wee optimal.

Reflective Polyethylene Mulch Reduces Mexican Bean Beetle (Coleoptera: Coccinellidae) Densities and Damage in Snap Beans
TLDR
It is suggested that growing snap beans on reflective plastic mulch can suppress the incidence and damage of Mexican bean beetle, and increase yield in snap beans. Expand
A Natural History of Ladybird Beetles
The Coccinellidae are a family of beetles, known variously as ladybirds or ladybugs. In Britain alone, some 46 species belong to the Coccinellidae family, although only 26 of these are recognisablyExpand
Movement of an insect parasitoid in simple and diverse plant assemblages
TLDR
Higher enemy colonization is expected in monorather than multispecific vegetation if the response of specialist natural enemies to habitat diversification is similar to that of monophagous herbivores. Expand
CHAPTER 7 – Culture and Colonization
TLDR
There are many and varied techniques for arthropod rearing, but differential cold storage of the sexes is useful for synchronizing emergence, because males of most of the insects develop more rapidly than females and emerge first. Expand

Suppression of Mexican Bean Beetle on Soybeans with Annual Inoculative Releases of Pediobius foveolatus
TLDR
Pediobius foveolatus (Crawford) was released annually in soybeans during 1972 and 1973 in preliminary attempts to suppress Epilachna varivestis Mulsant, and the results indicate a promising means of biological control for areas where E. varIVestis is economically important. Expand
