Banded Cucumber Beetle Lure
Latin Name: Diabrotica balteata
Lure: Coaster Lure Packet.
Lure Active Ingredient: Eugenol and 4-Methoxycinnamaldehyde
Field Life: 30 days
Trap to Use: Yellow Card
Monitoring Strategy: Sticky traps should be placed near plants spaced at least 30 m apart over a field, at least two feet above the top of the host plant. The number beetles on traps is recorded each time the traps are changed. The traps are typically changed every seven days but can last 30 or more days without significant reduction in catching ability. Since adult emergence can stretch over a period of four weeks, the traps should remain in the field for four weeks. If the economic threshold for yellow sticky traps of 6 beetles per day is reached there is a high potential for problems the following spring.
Cultural and Physical Control: Planting with variety, crop rotation, and early planting, as well as cover-cropping, compost application, and burning of diseased plant matter are pertinent preventative measures.
Distribution: North and South America (From Southern U.S. to Colombia and Venezuela), Cuba
Hosts: Cucumber, squash, beet, bean, pea, sweet potato, okra, corn, lettuce, onion, and various cabbages, with bean and soybean being its favorite hosts.
Description: Adult: 5-6 mm long. Elytra are yellow, marked with three transverse bands in shades of green or blue-green and a narrower longitudinal green line down the center.
Larvae: The new larva is white and about 2.3 mm long. It may turn yellow, though color depends on food source. The later-instar larva may reach nearly 9 mm.
Eggs: Oval-shaped, yellow, 0.5-0.6 mm long.
Life Cycle: The adult mates at about six days of age. The female begins producing eggs about 16 days later. She lays a cluster of eggs every few days for two to eight weeks, producing up to 15 clusters, for a maximum of 850 eggs. A cluster has up to 100 eggs, oviposited in a crack in the soil, and the eggs hatch in 5 to 9 days. The larva develops for 11 to 17 days, pupation takes 4 to 6 days, and the adult has an average life span of 26 days. There is no diapause. In the best conditions there can be six or seven generations per year.
