Larvae feed on the roots of the emerging plants, which causes the most damage since the young plants are more vulnerable. [1] In the adult stage the beetles cause damage by eating the flowers, leaves, stems, and fruits of the plant [1] The beetles can also spread diseases such as bacterial wilt and mosaic virus. [2]
Cucumber beetle is a common name given to members of two genera of beetles, Diabrotica and Acalymma, both in the family Chrysomelidae. [1] The adults can be found on cucurbits such as cucumbers and a variety of other plants. Many are notorious pests of agricultural crops. The larvae of several cucumber beetles are known as corn rootworms.
Since striped cucumber beetles are particularly attracted to plant seeds, monitoring of striped cucumber beetles is important when seedlings first begin to emerge in early spring. Previous studies have shown that striped cucumber beetles are most active in feeding during the morning and early evening. Furthermore, newly emerged plants are most ...
Squash mosaic virus (SqMV) is a mosaic virus disease common in squash plants and other plants, including melons, of the family Cucurbitaceae. [1] It occurs worldwide. [1] It is transmitted primarily by beetles, including the leaf beetle (Acalymma trivittata), spotted cucumber beetle (Diabrotica undecimpunctata), [2] [3] and 28-spotted ladybird beetle (Henosepilachna vigintioctopunctata), [1 ...
However, the insect growth regulator pyriproxyfen has been found successful in reducing whitefly populations on curbit plants including zucchini squash, cucumber, and pumpkin. [20] This hormone is a juvenile hormone analogue , which affects hormonal balance and chitin in immature insects, and causes deformation and death during molting and ...
They feed on the leaves, buds and flowers and can defoliate the plants; the grubs bore into the roots and damage the stems and fruits that lie on the soil. [4] A. foveicollis favours pumpkin ( Cucurbita maxima ) over other curcurbit crops, but will also feed on squash ( Cucurbita pepo ), melon ( Cucumis melo ), cucumber ( Cucurbita sativus ...
Leaf miners are regarded as pests by many farmers and gardeners as they can cause damage to agricultural crops and garden plants, and can be difficult to control with insecticide sprays as they are protected inside the plant's leaves. Spraying the infected plants with spinosad, an organic insecticide, can control some leaf miners. Spinosad does ...
Several spider species attacked both the eggs and adult stink bugs. The Joro spider, another invasive Asian species, was identified in Georgia in 2015, and is a natural predator of the stink bug. [72] Pill bugs eat stink bug eggs. [73] Arilus cristatus, however, was the most voracious predator and attacked the eggs and adults more consistently ...
