I have HUGE problem with fruit fly but would like to grow some interesting fruit trees. Any suggestions on what I could grow in a fairly small garden that is fruit fly resistant.

Sorry John have been away. I really don't know what sort of fruit fly does it make a difference?

Casimiroa seems to have a low fruit fly problem.
Greenharvest.com.au had a list of 18 tree species in their past catalogue early last year,including the Avocado,Custard Apple and Mulberry.

You could also think of growing dwarf varieties of the susceptable trees and then bagging the fruit to avoid them getting stung. i personally haven't done this but a friend has with her peaches and it worked well. Don't you just hate fruit fly. We were in Melbourne in January picking and eating plums of a backyard tree I was so envious.

Happy Earth - why are blueberries and grapes not affected by fruit fly? I'm interested seeing I just bought a blueberry bush and I had been thinking I'd have to net it. I was hoping to grow grapes as well. This is good news :)

I'm relatively new at this and that was a really interesting list you posted. With mulberries being sometimes affected - does it depend on seasons, the area or the variety?

I found a tomato variety in the Eden seeds catalogue that was listed as being fruit fly resistant. What would the difference be between that and other toms?

Hey Elf, not sure why blueberries and grapes are not affected - you'd think they would be. As with mulberries - this happens on occasions here in Wollongong but id say you be fairly safe in Albury. the first time i discover fruit fly in mulberries was when i was boiling the fruit for jam and the little grubs came up to the surface. Normally you cant see them!

As for tomatoes, I only grow cherry tomatoes (the ones that come up in worm castings or compost) as they seem resistant to fruit fly - so yeah its possible some tomato varieties are resistant and id say that is what they would be selling you.

Hope this helps,

Rich

I don't get fruit fly in my citrus, unless I leave the Valencias a bit too late. But most other growers in my area get it in oranges, mandarins and grapefruit. We only get the medfly in WA.

So I wouldn't rely on citrus being fly-free.

Thanks for your advice Rich and Julie. Do you think Pawpaw is growable in Albury or is the climate too hot and cold? I'd like to get the cutting grown one from Daleys when they're ready.

Really like the blog you and your other half have Rich, great garden. Green with envy :) Good luck!

Hi everyone,

I don't think Qld fruit fly stings citrus, but the introduced medfly in WA is quite a different animal.

I think (Qld) fruitfly does not usually attack things very close to the ground with small fruit like strawberries and blueberries, even if it is soft.

Orange pawpaw might grow in Albury but probably wouldn't be very sweet (like in Sydney).

Diana.

Thanks for your advice Diana, I was worried about my strawberries, they have just started to fruit - I really know nothing about fruit fly, but clearly I need to learn if I want to have fruit.

So does Albury have QLD brand of fruit fly?

Hi Elf,

If you are in WA it could be mediterranean fruit fly. On the east coast Qld fruit fly go down to south of Sydney, but not to Victoria. I'm not sure exactly where the southern range limit is.

First harvest of grapes - huge, bountiful delicious, all subsequent ones sickeningly
destroyed by fruit fly. Do not plant grapes in Brisbane unless you have some magical answer to this problem....

Hi Gardana,

The non-magical answer if you have this problem is to bag the grapes when they are small and green with either paper bags tied at the top, pestguard (from green harvest- they have a website), fly mesh, or those nearly transparent gift bags with fine weave. Bunches of grapes are a good shape and size for bagging.

I used to use old pantyhose to bag my grapes - not against fruit fly, but birds. (I guess it could work with fruitfly).

Seemed to work for a while, then they just poked through the bags and wrecked the fruit. Same with peaches. If they can see through it they will have a go.

I can confirm that in Sydney Qld fruit fly is a problem for wampi (half my crop ruined this Feb), yellow cattley guava and pepinos. Yes pepinos growing on the ground have to be bagged or in the warmer half of the year most will be ruined. So far no problem with papaya, red cherry guava, emperor and murcott mandarins. Not much problem with cherry tomatoes

When I was in Perth Med fruitfly did affect my grapes a little, although powdery mildew is the main problem for most grape varieties.

What should be safe in Sydney: Garcinias, Ice-cream-beans, Jaboticabas, Soh-sang, Lychee, Peanut Butter Fruit, pomegranates, dragonfruit, Pouterias, Kiwifruit, passionfruit, most Citrus, most berries.

What hasn't been safe for me: cherimoya, guavas, feijoa, fig, early persimmons, stone fruit.

Fruit fly in Sydney will also attack banana passionfruit because of its thin skin, tomatoes (even cherry tomatoes to some extent), capsicum, pawpaw, jujube.

Olive, Pitomba and yellow jaboticaba are safe. Non-astringent persimmon is usually OK as long as it is picked when still hard - any fruit fly stings can be cut away before eating.

I've also found that some of my Fuyu Persimmons (early season) get attacked (although I have more problem with ringtail possums).

Not attacked include cape gooseberries.

There are vastly more fruit fly around during the warmer half of the year, so anything fruiting during the warmer time is more likely to get attacked. Sometimes my ruby red grapefruit ripen too early (February) and are attacked, whereas the ones that crop normally (September) are not attacked.

Also some thick skinned fruit like passionfruit may be attacked but the pest doesn't get through the skin.

Dave, netting the persimmon tree works well for me in preventing possums and birds.

It does depend on the season and whether the conditions are favourable (ie. wet and humid)and the pest pressure in your neighbourhood.

Figs: definitely prone. Though they tend to get stung when they are ready to be picked. I have only occasionally found maggots in the fruit.

Citrus: grapefruit definitely susceptible due to the thin skin, though they have thick pith. Even though the egg/maggots may not penetrate the white pithy section the fruit gets a fungal pathogen at the sting site and drops. I always lose a certain % of grapefruit at colour break. Fruit held late spring will develop maggots if not protected.
Oranges: susceptible to being stung at colour break, causing them to drop prematurely, usually from secondary fungal infections.
Lemons: any left too long on the tree will get stung in spring and be ruined.

Raspberries: contrary to what some sites say and the claim from what someone living in QLD told me, raspberries are very prone to fruit fly. So much so that I regretfully pulled all mine out.

Avocado: haven't noticed any stings or damage.

Feijoa: = magnet; net or expect zero edible crop.
Pink Guava: see Feijoa.

Stone Fruits: goes without saying, these will be decimated without netting.

Apples: will get stung early after fruit set; the fruit tries to heal the wound--but the weeping clear sap like fluid invites fungal infection and the fruit drops prematurely.

Passionfruit: will occasionally get a few stung, but yet to see any make it to the pulp.

This year I noticed first hand that immature baby pumpkins with thin unhardened skins, being stung by fruit fly. The question now is whether these pumpkins will keep or develop mould in storage at the sting sites.

Feijoa - yep it's a shocker both in QFF territory and in Med Fly country (SW WA).
Pink guava - I know where there's one in a park in Sydney that doesn't get attacked - but the fruit on that tree are very bland tasting (my guess is that's why QFF don't bother them)

Thanks Edward,
Re persimmon tree - I've been using medium size fruit fly bags (organza bags) which work well for fruit fly, but they're no use against ringtail possums.
The tree's getting a bit big for me to get a net over, but it's a possibility.

some people are saying pomegranate to be resistant. this is known to be untrue. lots of people have pomegranate that get affected, even with their thick skin. I keep all fruits in the mesh bags now as lots of things get affected unfortunately.
