Nothing ruin the joy of harvesting sweet , advanced strawberry quite like finding them riddled with tiny holes or tunnel The culprit ? Strawberry sap beetles These lilliputian pests invade ripe and overripe strawberry fruits , marring their appearance and causing them to moulder quickly .
Getting disembarrass of sap beetle organically in your strawberry mend rent industriousness , but it can be done . Here are effectual method to operate strawberry sap mallet without chemicals .
Identifying Strawberry Sap Beetles
The first footprint is confirming strawberry sap beetles are the causa of damage , Look for
grownup sap beetles are oval flattened dark brown to black insects . They have antennae with gild on the destruction . Ripe fruits damaged by other pests attract sap beetles to feed and lie testis . Their larva continue damage the yield from the interior out .
Why Control is Important
Strawberry sap mallet damage may seem minor at first . But leave uncontrolled , sap beetle population will breed apace , ruining more and more of your hemangioma simplex harvest . Sap beetles also :
Prompt sap mallet controller keep your strawberry glean usable and prevent population explosions on your farm or in your garden .
Organic Ways to Get Rid of Strawberry Sap Beetles
These constitutional methods can help you control sap beetle without using chemical insecticide :
Remove Infested Berries
Check ripe berries daily and discard any with sap mallet price .
Remove and demolish overripe or rotten fruits that draw in sap beetles .
Bury discarded fruit deep or seal in plastic bags to kill larvae inside .
Use Traps
Set out traps with fermenting baits like wheat scratch , acetum , or ripe fruit .
Place traps along edges of your strawberry temporary hookup to intercept beetle .
Empty and refresh bait every 2 - 3 days to keep traps efficacious .
Keep Harvests Clean
Pick berries daily as they ripen to prevent overripe fruits .
Wash off berries instantly after pick to remove eggs or larva .
Keep ground debris - gratis to excrete beetle hiding spots .
Weed out unwarranted Berry , tree fruit , and alternate host near your patch .
Use Floating Row Covers
Cover row with lightweight framework row cover to boot out beetles .
Secure edge with soil or rocks to keep covers in situation .
Remove cover when berries start out to mature to allow pollination .
Replace embrace after daily harvests to boot out more beetle .
Apply Kaolin Clay
Spray fruits with kaolin clay coats which deter sap beetle from feeding .
Reapply after rain to conserve protective roadblock .
Always travel along recording label directions when applying to edible crops .
When to Use Pesticides for Sap Beetles
While organic method are ideal , sometimes pesticides are ask to quickly repress high strawberry mark sap mallet population . Consider chemical ascendence if :
Traps and sanitisation give out to protect mature fruit .
mallet damage escalates to more than 10 % of your crop .
Harvests are nearing their peak with continued sap mallet issues .
you could not take away infested fruit fast enough to stay forward of beetles .
If pesticide sprays are need :
Treat crops at first signs of sap beetle terms . Do not wait until fruits are ripe .
Select targeted , low-toned perniciousness pesticides labeled for strawberries .
Combine sprays with traps , run-in covers , and Good Agricultural Practices .
Preventing Strawberry Sap Beetles
Once you get sap beetles under control , focus on prevention to avoid recurrent upshot :
Use worm exclusion fabric run-in covers too soon in the season .
Eliminate gage , detritus , and alternate mallet hosts around your strawberry maculation .
employ kaolin mud coatings preventively before fruits start ripening .
Maintain a strict harvest schedule , remove all advanced fruit daily .
Scout for the first sign of sap mallet damage and act quickly .
Rotate hemangioma simplex planting internet site each year to interrupt plague cycles .
With good sanitisation and a admixture of organic controls , you’re able to keep strawberry sap beetle in check and enjoy bountiful , scathe - devoid berry harvest .

Sap Beetles in Florida
There are more than 4,500 species of sap beetles , with about 165 metal money in North America . Twenty - one genus have been account in Florida including Carpophilus , Stelidota , Glischrochilus , and Epuraea ( Myers 2001 ) . Species in these genera are typically the most problematic farming pests . In Florida strawberries , Potter et al . ( 2013 ) find 9 metal money in seven east Hillsborough County fields ( Plant City , FL ) . Here is a list of the specie that are most common : Lobiopa insularis , Carpophilus fumatus , Carpophilus humeralis , Carpophilus freeman , Stelidota geminata , Stelidota ferruginea , Carpophilus mutilates , and Colopterus insularis .
Approximately 94 % of the sap mallet were the top three specie : E. luteolus , L. insularis , and C. fumatus ; however , condition must be given to all specie . Correct identification should be followed by preventative method acting to control damage by sap mallet .
Sap beetle adult fly into strawberry field from surrounding field or wooded surface area . In temperate areas , trajectory happen when beetles derive back from wintertime and when temperature arise above 16 ° 100 ( 67 ° F ) and strawberries start to mature ( Blackmer and Phelan 1995 ; Loughner et al . 2007 ) . In Florida , sap beetle are common later in the harvest season , from February to March , when the weather condition get warmer and fields full of pretty but damaged strawberry start to jam up ( terms and Nagle 2013 ) .
Both adult and larval sap beetles attack and feed on fruits . seniority of adults is just about 2 to 2½ months . A few 60 minutes after union , most specie lay their bollock on or under damage or thrown away yield , but some put down their orchis in the ground . After hatch from eggs , larvae burrow up into berry , feed on the flesh for approximately 1½ weeks . Larvae then fall to the ground , burrow into the soil , and pupate . Sap beetle can recover food in many berth , but most of the time they eat fungus that grows on ripe and overripe industrial plant constituent , fruits , and other plant parts that are transgress down or ripening ( Peng and Williams 1990 ; Myers 2001 ) .
Sap beetles do two sort of terms : verbatim ( by make hole or enclosed space for solid food ) and collateral ( by distribute microorganisms ) . Cavities also dish as egg - laying sites . Larvae inside hemangioma simplex usually go unnoticed until the fruit begins to decompose as a result of the harm . Because sap beetles like overripe strawberry mark , the most damage fall out when pickers leave ripe and overripe strawberry flora in the field or throw away yield in ditches or along underweight field sharpness ( Figure 4 ) .
Sap beetles do n’t usually anguish the saving when strawberries are picked in the field and sold right out . But when overripe strawberries are picked to be processed , sap mallet may get into the fruit and make it unsellable . consider the ecology of sap beetles , the following pattern are recommended .
If potential , keep off planting strawberry mark next to wooded areas . For timing controls , it ’s important to keep an oculus on when sap beetle fly into field next to wooded area . To turn back sap mallet from do into your field , put down booby trap traps ( credit card cup buried affluent with the ground and partly filled with oily H2O ) or “ trap buckets ” ( an about 1 - gallon bucket partially fill with soapy water and containing an 8 - snow leopard credit card cup with fermenting banana , strawberry mark , or other fruit or bread dough placed in the bucket ) .
Pick berries oft , before they become overripe . Take out any damaged or overripe yield from the field , but do n’t throw them away in weedy areas , especially when it ’s hot . Another good means to cut down on the number of grownup in the field might be to plunk infected fruit and put it in the middle of the row ( Potter 1995 ) . In between course , fruit break down faster than sap beetle can finish their life cycles , which stop their hertz . Keep in head that ferment berries may attract sap beetles capable of migrate from long distances ( ceramicist 1995 ) . Similar sanitation pattern should be done with other fruit and vegetables .
A nematode parasite of one sap mallet species has been documented ( Dowd et al . 1995 ) . A commercially - uncommitted beneficial nematode ( Steinernema carpocapsae ) ( eg , Millenium , BASF Corp. ) is in effect against soil - home stage of other strawberry mark mallet cuss and may aid keep sap mallet away .
A small parasitic wasp called Bradyserphus abruptus has been raised from several metal money of sap beetle and 99 % of the time , young sap beetle larvae were infected , which stopped the wasp adults from emerging ( Williams et al . 1992 ) .
Apply urge insecticide when conditions justify . Assail ( acetamiprid ) , Brigade ( bifenthrin ) , Danitol ( fenpropathrin ) , and Rimon ( novaluron ) are insecticide that can be used to get disembarrass of sap beetle ( Price and Nagle 2013 ) . Rimon is an dirt ball - growth regulator and is only effectual against sap beetle larvae . One of the other products on this list that works against adult sap beetle can be desegregate with Rimon in a army tank .
Biopesticides that hold azadirachtin or neem oil ( like Azatin , Neemix , and Trilogy ) will stamp out larvae and pupa and keep larvae and adults from course . Fungi that are insecticide ( like Mycotrol O , Naturalis , and PFR-97 ) can vote out larvae after being used several times and when the humidity is mellow . Products contain pyrethrins may also be used .
