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 ...
Besides removing the insects by hand or including trap plants to lure away bugs, you can bring in (native) ladybugs as well. A ladybug larva can eat 50 aphids a day. A ladybug larva can eat 50 ...
In the United States, two species are major pests of cucurbits, the striped cucumber beetle (Acalymma vittatum), which is mainly found east of the Mississippi River, and Acalymma trivittatum which is mostly found west of the Mississippi. [2] Adults feed on young leaves, and larvae can damage roots. [3]
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta, a paraphyletic group which Apocrita (wasps, bees and ants) evolved from), and flies . Some beetles also exhibit this behavior.
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 ...
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 ...
