What Is A Grapevine Beetle?
The grapevine beetle ( Pelidnota punctata ) , is a type of scarab that is found in eastern and fundamental parts of North America .
They are link to the Junebug , and sometimes call a ‘ spotted June beetle ’ . Like their more unwashed relative , they ’re nocturnal and attracted to lustrous illumination .
What Do They Look Like?
First off , they ’re heavy to escape because they are HUGE . They ’re easily two - three times larger than a Junebug , and in reality kind of scary looking the first time you see one . YIKES !
If their size is n’t enough to make a prescribed ID , then look for other identify characteristic . The colouring vagabond from bright orangeness to light tan , and they usually have black spot on their back ( though some may not have spots ) .
They fly around at night , and are just as clumsy as their more popular congener . If you enquire me , they bet like they ’ve been imbibe when they fell .
But do n’t allow this fool you , they can still move jolly darn fast . Their size of it and clumsy way of life of locomotion makes them easy to discern when they ’re buzz around .
Grapevine Beetle Life Cycle
There are four leg to the grapevine beetle life round : grownup , egg , larva , and pupa . The adults lay their eggs in the soil , and the larvae hatch a few week later .
The larva are gravid white grub worms that burrow deep into the ground , where they overwinter until spring . As the soil warm up , they slowly make their way back to the surface , where they feed in on rotting Sir Henry Wood .
Once they ’re matured enough , the grubs pupate near the surface of the dirt , and they come forth as grownup mallet sometime in July . There ’s only one generation per twelvemonth .
What Do They Eat?
As their name suggests , these beetles like to eat the leaves and fruit on both wild and tame grapevines . They can fertilize on other types of fruit too ( like apples and raspberries ) , but it ’s pretty rare .
The larva eat rotting organic material , so they are actually reckon beneficial . Thankfully , the larvae do not feed on industrial plant . Only the adults do that .
Damage To Plants
They can damage works by eating hollow in the foliage or fruits . They will skeletonize the leafage , and can also put down the fruit .
However it ’s very rare for them to do major damage to the plant . This is because they are n’t usually rule in large phone number .
What’s Eating My Grapevine Leaves?
Just because you find damage on your flora does n’t mean you have grapevine beetle . The more probable culprit is Nipponese beetles .
Those plaguey bugs absolutely love my word of mouth , and banquet on them every summer . They ARE major garden cuss , and like to congregate in gravid numbers . But they ’re much modest and iridescent super acid and brown . take all about how to identify and hold in Japanese beetles here .
Are Grapevine Beetles Harmful?
Luckily they are not harmful to humans or pets , and they do n’t sting or sharpness . They are also seldom harmful to industrial plant .
Even though the grownup beetles primarily feed on grapevines , they are n’t considered major pests in vineyards . So it ’s highly unlikely they would cause major problems in your home plate garden .
A major infestation certainly could induce harm , but it ’s pretty rare . So do n’t interest if you see one or two of them flying around your neighborhood .

Hand Picking
Since they are so big , it ’s easy to hand find fault them from the plant and drop them into a bucket of soapy water . I find thatDr . Bronner ’s melted soapworks very tight to kill bugs .
But , since they are nocturnal , it may be concentrated to find them . So I recommend going out in the later evening or other cockcrow to hand pick them when they are still out , but not as active .
Diatomaceous Earth
If hand plunk them is just too much to bear ( and I do n’t charge you for that ! ) , then you could try out a more hands - off approach . Diatomaceous earth(DE ) is an all - natural Cartesian product made from crushed up hard - crush organisms .
Sprinkle it directly on the grape vine beetles . It will get under their shell and cut up their soft bodies , eventually killing them .
Insecticidal Soap Spray
Anorganic insecticidal soapspray can make for to appal them so they ’re easier to pick from the plant life . you’re able to amalgamate your own using 1 teaspoon ofmild liquid soapto 1 liter of water .
You have to spray it straightaway on the bug though , or it wo n’t have any effect . Also , it in all likelihood wo n’t kill them the right way away , so apply it to stun them before hand - pick .
Beneficial Nematodes
Another organic method you’re able to taste isbeneficial nematodes . These are tiny predatory parasites that live in the soil and provender on the larva ( grub worms ) .
For best result , apply them in the evenfall or spring when the grubs are close to the ground surface . show all about how to apply beneficial nematode here .
Milky Spores
Harmless to beneficial hemipteron , milky sporeis a naturally occurring bacterium that infects the grubs when they wipe out it , and finally pop them .
The downfall is that it can take 2 - 3 year for this method acting to be effective . But once active , whitish spores last in the stain for several years .
