Insect Control

NOTES:  For the insecticides listed below, one product trade name and formulation is provided for each active ingredient (AI) as an example of rates, preharvest interval (PHI), restricted entry interval (REI), and special instructions. In many cases, there are other products available with the same AI. Please see Table 26 and Insecticides Alphabetical Listing by Trade Name for more information on these insecticides.

The designation (Bee: L, M, or H) indicates a bee toxicity rating of low, moderate, or high. See the Protecting Honeybees and Native Pollinators section for more details.

The symbol * indicates a product is a restricted use pesticide. See Pesticide Safety and Use for more details.

The symbol OG   indicates a product is listed by the Organic Materials Review Institute (OMRI) as approved for use in organic production. See Organic Certification section for more details.

Caution: Insecticides should not be applied when bees are active in the field.  Avoid products with high or moderate bee toxicity during bloom. If application of an insecticide is necessary while the crop is blooming, select products with low bee toxicity or with short residual period; apply in the evening after the bees have left the field. See Protecting Honeybees and Native Pollinators in the Insect Management section for more suggestions on how to avoid harmful effects on pollinators.

Aphids, Green Peach (Myzus persicae ) and Melon (Aphis gossypii)

Aphids found in cucurbits include green peach aphid and melon aphid. See Peppers for more information about green peach aphid. Melon aphid has a wide host range; vegetable crops attacked include cucurbits, asparagus, pepper, eggplant and okra. Among cucurbits, it is more serious on cucumber, muskmelon and watermelon than in squash and pumpkins. Varieties differ in susceptibility. Melon aphid overwinters in the north on woody plants including catalpa and rose of Sharon; more southerly, adults survive on cold tolerant plants including spinach and dock. Life cycle is similar to green peach aphid; winged females colonize crops in early summer, and wingless females produce live young for about 15 days (70 to 80 offspring per female) resulting in multiple generations. The time from birth to reproductive adult can be 1 week. Wingless females are 1 to 2 mm long. Color varies from light green mottled with dark green (most common) to white, yellowish or dark green. The cornicles at the tip of the abdomen are always black, a key diagnostic feature. Melon aphid outbreaks are more common in hot, dry weather.

Infestations occur on undersides of leaves where aphids extract plant sap with their piecing sucking mouthparts. Feeding causes yellowing, puckering, leaf curling, and leaf death at high numbers along with shiny honeydew deposits and buildup of sooty mold. Viruses transmitted by melon aphid include cucumber mosaic, watermelon mosaic, and zucchini yellow mosaic. Because transmission occurs within 15 seconds of feeding, insecticides may not prevent initial virus infection though they may reduce its spread in the crop. Oils may reduce virus transmission but test for phytotoxicity.

Use of reflective or row covers to prevent early infestation and virus transmission. Reflective mulch confuses aphid orientation and reduces their ability to locate and infest plants.  Direct seeding is recommended in reflective mulch for maximum effectiveness. When using row cover, apply immediately after setting transplants or seeding, and be sure transplants were not infested while in the greenhouse. Cultivars differ in susceptibility to aphid buildup and to virus; plant resistant varieties if they are available. Separate early and late plantings.

Scout for aphids beginning in mid-June by searching undersides of leaves on runners. If 20% of runners or more have live aphids treatment may be needed. Good coverage of undersides of leaves is needed with materials that require direct contact with pest; translaminar products help to reach aphid feeding sites. Use selective insecticides for other pests to conserve natural enemies.

Cucumber Beetle, Striped (Acalymma vittatum) and Spotted (Diabrotica undecimpunctata)

Striped cucumber beetle is a key pest of all cucurbit crops in New England, one that requires cultural and often chemical controls to prevent direct feeding damage and transmission of bacterial wilt.  Adult beetles are 7 mm long, are yellow with 3 black stripes that reach the end of the forewings, and have a yellow thorax and black head. Adults overwinter primarily in field edges near last year's crop, with a small proportion remaining in the field. With the onset of warm days (> 50° F), beetles feed on pollen in early-blooming wild plants. High tunnel and greenhouse cucumbers draw beetles first, followed by early field crops. Eggs are laid in soil at the base of the stem, and larvae feed on roots. After pupation in the soil, 'summer adults' emerge, generally in late-July and August. Summer adults feed until early fall, when they move to overwintering sites. Some may produce a second generation which emerges in the fall. There one generation per year in northern New England and a partial second generation in southern New England.

Beetles can colonize a field very rapidly. Adults cause direct feeding damage to cotyledons (often as gouges on underside), leaves (ragged holes) and the base of the stem (wounds and scars). Wounds on the stem allow entry of soil-borne pathogens. Once flowering begins, beetles congregate in flowers.  At high numbers, adults may cause pits and scars on fruit. Larval root feeding, hidden but important, reduces plant vigor and yield. The striped cucumber beetle also vectors Erwinia tracheiphila, the causal agent of bacterial wilt. The pathogen overwinters in the beetle gut, and is transmitted through fecal material deposited in feeding wounds. The bacteria then invade the vascular system of the plant. Non-infected beetles can become infected by feeding on infected plants. Cucumber and muskmelon are highly susceptible to wilt; watermelon is not. Seedlings at the cotyledon and 1- to 3-leaf stage are more susceptible to infection with bacterial wilt than older plants. Thus, it is especially important to keep beetle numbers low before the 5-leaf stage.

Use crop rotation, moving spring crops as far as possible from last year’s fields and overwintering areas. Exclude beetles by using use row covers, supported by hoops to prevent abrasion; remove at flowering to allow pollination. Use transplants so that plants reach at least the 3- to 4-leaf stage before beetles arrive. Some repellents or systemic insecticides may be applied to transplants outside the greenhouse before setting in the field, and some may be applied through drip irrigation. See cucumber beetle in the insect control section of Pumpkin, Squash and Gourds for information on using trap crops to protect a main crop of cucumbers and melons from beetle damage.

Scout twice per week from emergence to 3-leaf stage, then weekly. Count beetles per plant and note damage to leaves and stems. The economic threshold depends on the crop. To prevent bacterial wilt in highly susceptible crops such as cucumber, muskmelons, summer squash, and zucchini, treat when there is 1 beetle for every 2 plants. Less wilt-susceptible crops (butternut, watermelon, most pumpkins) will tolerate 1 or 2 beetles per plant without yield losses. Spray within 24 hours after the threshold is reached. Timely and effective early control will prevent the need for sprays during flowering when bees are active in the crop. There are few options for bee-friendly insecticides to use during flowering; if sprays are needed, apply in the evening after bees have stopped foraging. 

Spotted cucumber beetle does not overwinter here but disperses from more southern areas, reaching New England in mid to late-summer.  Also known as southern corn rootworm, it feeds in a very wide range of crops and weeds and is often found in flowers. Adults are yellowish green with 12 black spots and a black head.  Immature stages are in the soil. This pest rarely builds up to damaging levels in New England.

Two-spotted Spider Mite (Tetranychus urticae)

Also known as Red Spider Mite. Outbreaks are often caused by the use of broad-spectrum insecticides that kill beneficial insects that normally keep two-spotted spider mites (TSSM) populations in check. Watch for white speckling on the upper surface of leaves or webbing on the undersurface around leaf veins. Avoid early-season, broad-spectrum insecticide applications for other pests. Use selective products whenever possible.  With most miticides (not bifenazate), use 2 applications, approximately 5 to 7 days apart, to help control immature mites that were in the egg stage and protected during the first application.  TSSM are prone to developing pesticide resistance so be sure to alternate between products after 2 applications to help prevent or delay resistance.
