What's eating my indian summer raspberry?

Indian Summer raspberry faces the classic cane-fruit pest lineup: aphids spread raspberry mosaic virus, spider mites thrive in summer heat, and raspberry beetle larvae tunnel through ripening fruit. Japanese beetle is a significant defoliator in North America. Birds and deer are common vertebrate threats to canes and fruit.

Curled, distorted leaves on shoot tips; virus transmission causes mosaic mottling across the plant. Remove infested tips; spray with insecticidal soap; choose virus-resistant varieties and manage nearby weed hosts.

White grubs found inside ripe berries, making fruit inedible; adult beetles notch flower petals in late spring. In the US, pyrethrin sprays at pink-bud and petal-fall stages; in UK, approved insecticides at first pink fruit stage. Hand-pick adults.

Pale, bronzed foliage with fine webbing under leaves; worst in hot, dry summers. Maintain moisture; apply neem oil or insecticidal soap to leaf undersides; avoid dusty, dry conditions.

Ripe berries pecked and removed; entire fruiting clusters may be stripped quickly. Net canes with fine bird netting once fruit starts to ripen; remove after full harvest.
