DESCRIPTION OF THE PESTS
Adult crickets are black or brown, and are 0.6 to 1 inch in length.
Eggs are laid in the ground, mostly in damp places. Crickets are present in all
stages all year round.
Crickets generally do not cause economic losses in cucurbits.
Crickets can cause some damage initially by eating flower parts and causing
poor or incomplete pollination. Also, as fruit reaches the full slip stage,
this pest can enter the stem end and feed internally on the fruit. Excrement of
crickets can spot melons, resulting in exterior dark stains that may affect
Crickets are usually more of a problem in areas of the field near
weedy areas during stand establishment. Clear weeds early in spring before
crickets mature and begin to migrate. Treat if damaging numbers of insects are
observed during field inspection.

|The following are ranked with the pesticides having the greatest IPM value listed first—the most effective and least harmful to natural enemies, honey bees, and the environment are at the top of the table. When choosing a pesticide, consider information relating to air and water quality, resistance management, and the pesticide's properties and application timing. Not all registered pesticides are listed. Always read the label of the product being used.
||MODE OF ACTION GROUP NUMBER1: 1A
||COMMENTS: Apple pumice baits work better for crickets and
grasshoppers than bran baits. Baits lose their attractiveness as they dry
out. Apply in early evening to avoid drying out too soon from sun exposure.
Use suitable ground or aircraft equipment that provides good distribution. A repeat application is usually necessary for effective control.
