The striped cucumber beetle (Acalymma vittatum (F.)) is a destructive pest of cucurbit crops, and management could be improved by host plant resistance, especially in organic farming r, despite the variation in striped cucumber beetle preference observed within the economically important species, Cucurbita pepo L., plant breeders and entomologists lacked a . The bacterial wilt organism, Erwinia tracheiphila, overwinters in the bodies of both the striped and spotted cucumber beetles. The adult striped cucumber beetle is one-quarter inch long and is yellow-green with three black stripes down its back. Spotted cucumber beetle is one-quarter inch long and yellow-green with 12 black spots on its back.
Bacterial wilt is caused by a bacteria (Erwinia tracheiphila) spread by both the spotted and striped cucumber beetles. Initially, it causes leaf wilting along the stem, but over time it will spread throughout the plant and die. To avoid this wilt, eradicate cucumber beetles and their larvae as quickly as possible. If you find an infected plant. Muskmelon Cultivar Attractiveness to Striped Cucumber Beetle and Susceptibility to Bacterial Wilt. Authors: Ahmad Shah Mohammadi 1, Elizabeth T. Maynard 1, Ricky E.

Acalymma vittatum, ‘Striped Cucumber Beetle’ Acalymma vittatum. Source: Jesse Christopherson. In the other genus which comprises the cucumber beetle population, we have the striped cucumber beetle. This is a severe pest for crops in both larval and adult phases of life. It feeds primarily on adult form prefers older plant. A. vittatum is the most important pest of cucumber and cantaloupe east of the Rocky Mountains in the USA (Gould, ; York, ; Brust et al., ).Crop loss from the direct result of striped cucumber beetle feeding in cantaloupe is usually not that important but the transmission of Erwinia tracheiphila is. Crop losses can be between % of plants in a field (Gould, ).

Cucumis species resistance to striped cucumber beetle seedling feeding and bacterial wilt. Peoria, Ill.: U.S. Dept. of Agriculture, Agricultural Research Service, North Central Region, (OCoLC) Striped cucumber beetles and bacterial wilt. Jerry Brust, UME. Striped cucumber beetles (Acalymma vittatum) (SCB) are the most important insect pests of muskmelon and cucumbers in our area.
They overwinter as adults and emerge when temperatures reach 54–62°F at which time they begin searching for cucurbit hosts. though striped cucumber beetles (Acalymma vittatum)are cucurbit specialists, closely related Diabrotica species, including spotted cu-cumber beetles (Fig.
7), are polyphagous and occur commonly in cucurbit fields (Fisher et al. ; Metcalf and Lampman ). The role of spotted cucumber beetles and other Diabrotica species. Effect of Root Feeding by Striped Cucumber Beetle Larvae on the Incidence and Severity of Fusarium Wilt of Muskmelon R.
Latin and G. Reed Assistant professor, Department of Botany and Plant Pathology, Purdue University, West Lafayette, IN and research entomologist. Striped cucumber beetle carries the bacterial wilt pathogen that can cause plants to wilt and die. Cantaloupe and muskmelons are severely affected by bacterial wilt.
These beetles become active in late May or early June and feed on the blossoms of early flowering plants, such as dandelions, apples and hawthorn, until their host crops are available. BW - Bacterial Wilt Resistant Cucumbers. Download Catalog Country Of Origin. County Fair Cucumbers.

Reimer seeds has over 5, quality vegetable, flower, and herb seeds for the home gardener and market growers. Causes of Bacterial Wilt on Cucumbers. Bacterial wilt is caused by the bacterium Erwinia tracheiphila, which is spread when the striped cucumber beetle or the spotted cucumber beetle feeds on the plant’s leaves.
The bacteria can overwinter in the beetle’s digestive system or the insects may pick it up while feeding elsewhere. By cucumber wilt I assume you are referring to bacterial wilt, which cucumbers are very susceptible to. As far as how the bacteria interact with resistant varieties, the mechanism isn't well understood.
I would guess bacteria could still survive in resistant varieties, but it isn't known for sure. Bacterial Wilt. Cucumber beetles carry the bacteria that causes bacterial wilt in their guts.
As these beetles feed on your cucumber plants they can spread it through their mouths and feces. Once the bacteria has been introduced it spreads quickly and causes the leaves of your cucumbers to wilt.
The bacteria are carried from plant to plant by striped or spotted cucumber beetles. The beetles spread the wilt bacterium by feeding on infected vines and then feeding on healthy plants.
Bacterial wilt can be reduced in your garden if the beetles are kept under control at the first sign of activity. Any corn with a tight husk will be more resistant to earworms. Specifically resistant varieties include Country Gentlemen, Golden Security, Seneca, Silvergent, and Staygold.
Cucumber beetles: In general, cucumber beetles prefer zucchini-type squash over others and. Cucumber (Cucumis sativus)-Bacterial Wilt Cause Erwinia tracheiphila, a bacterium that overwinters in the bodies of the striped and spotted cucumber beetles.
In Oregon, the disease is. Ten muskmelon (Cucumis melo) cultivars were tested for their susceptibility to bacterial wilt, caused by Erwinia tracheiphila and vectored by the striped cucumber beetle Acalymma vittatum. Cultivars Super Star, Rising Star, Pular, Caravelle, Cordele, Legend, Makdimon, Galia, Rocky Sweet and Passport were used in field studies to determine the number of striped cucumber beetles, feeding damage.
Following the separation of the roots and stems, a white-grey bacterial fluid flows out of the vascular tissue. The bacterium does not resist more than a few weeks on the plant debris, but it is transmitted by the striped cucumber beetle (Acalymma vittata) and the spotted cucumber beetle (Diabrotica undecimpunctata).
Bacterial wilt of cucurbits is an economically important disease that impacts most Cucurbitaceae species. The pathogen, Erwinia tracheiphila, is a vascular-inhabiting bacterium overwintered and transmitted by cucumber beetles. Disease management relies on controlling cucumber beetles, mainly through insecticide applications.
Striped and spotted cucumber beetles can cause damage in vine crops, but the striped beetle is more common in Wisconsin. Feeding from larvae and adults causes direct damage to roots, leaves, flowers, and fruits. Adults can also vector fusarium wilt and the bacteria, Erwinia ers and melons are particularly susceptible to bacterial wilt, and damage from this can be severe.
Cucumber beetles and bacterial wilt are major constraints to production of cucurbit crops. Striped and spotted cucumber beetles (Figures 1 and 2) can cause extensive damage by feeding on leaves (Figure 3) and rinds of cucurbits, but they have a greater impact on yield when they transmit bacteria that cause bacterial wilt (Erwinia tracheiphila).
I think that seedlings are even more susceptible than seeds, and so I always grow my squash family plants from seed in the garden, rather than transplanting. Striped Cucumber Beetles are about 1/4 inch long, with a rectangular back striped yellow and black.
They will feed on all cucurbits except watermelon, plus tomatillos and a few other plants. Bacterial wilt epidemics are strongly associated with striped cucumber beetle pop ulation den sity and behavi or (Fleisch er et al.
), indicat- ing the impor tance of this bee tle as a vector. In Pennsylvania for example, application of the neonicotinoid imidacloprid on seedlings resulted in reduced striped cucumber beetle colonization and bacterial wilt transmission.
Seedlings and small plants are most susceptible to cucumber beetle feeding damage and to bacterial wilt (Yao et al., ; Hoffmann et al.,).
Using transplants avoids exposure to cucumber beetle feeding during the most susceptible plant stages. Resistance to the banded cucumber beetle Diabrotica balteata (Le Conte), the western spotted cucumber beetle Diabrotica undecimpunctata (Mann.), the spotted cucumber beetle Diabrotica undecimpunctata howardi (Barber), and the western striped spotted cucumber beetle Acalymma trivittata (Mann.), has been studied by numerous workers.
Seedling. The striped cucumber beetle (Acalymma vittatum (F.)) is a destructive pest of cucurbit crops, and management could be improved by host plant resistance, especially in .
