Proud to Represent Hawaii

Hawaii often gets left out of many agricultural events.  People often ask me why.  It is simple: fruit flies.  They have made our exporting of produce difficult for the last 100 years.  With that being said, they have also made it the most challenging place to grow many otherwise common vegetables.  Marketing has showcased pineapple and sugar, two plantation crops that are uneffected by these pests. But we are not so proud to note that every year, new agricultural pests erode what small food production we have in the Hawaiian islands. When asked why I didn’t bring squash to the expo, other growers just shake their heads.  Those who have been around a while usually say, “oh fruit fly? Lucky you are growing anything at all.”  They are right.

It is for that exact reason that I began researching, and later breeding squash for Hawaii, and other areas with tropical fruit flies, and the newer introduction, Pickle Worm.  When California gets an invasion of fruit flies, they sound the alarms.  When Hawaii gets a new pest, it barely makes the news.  Another one, is not what any of us need.  But they continue to come in every year.  That is one of the many downsides of importing over 90% of your food.  It leaves the door open for pests from around the world to enter the islands.  Don’t believe me, try talking to someone from Australia.  We have many of the same issues.  I had more than one person ask for my squash at the National Heirloom Expo last year, I had to direct them to the images on my booth,  often the response was, “couldn’t you smuggle one in?”  I know they meant well, wanting me to represent my breeding and farming efforts with the real thing, but the very last thing I want to do is destroy California agriculture so that I can have something to show.  I explained the magnitude of what one selfish act could do.

But after having so many inquiries, I just thought my way through the situation.  Though I could not bring squash into California, or anywhere else in the US, I could get seed through. I wanted to collect more research data, as I entered year 4 of my farm’s independent research for squash in Hawaii.  It was brought to my attention, that maybe I should include it in the Baker Creek squash trials.  I will be telling that story at a later time, but for now, I just wanted to share the very good news that the Hawaiian Black Kabocha not only survived, but it produced in a very different environment, and surrounded by all new pests, and squash virus.  Why does this matter?  It matters in many more reasons other than having a squash in the line up at the expo.  It is another potential solution for islands and areas suffering from both fruit fly and drought.  It can be a solution for the food production efforts of other places.  The labors of one can help many.  After the expo I received an angered email that noted how self-centered my actions were.  Now, it was time for me to shake my head, knowing in my heart, he couldn’t be further from the truth. So Hawaii, this was for you.  Mahalo nui loa for the dozens of top ranked chefs who taught me the nuances of flavor, so that I could be a better informed squash breeder.  Because it is simple, if I am going to be breeding for pest resistance, I may as well breed for excellence in flavor and texture as well.  Hit that ball out of the park for all of us.

So here she is sitting pretty in the line up.  Only a Hawaii grower knows how much that means to get her there.

Well after 15 years plus of drought in the area, it is now the rainiest season in years. This well timed ultra rare squash from Armenia burst through it’s protective paper bag as it absorbed the gorgeous rain. I use brown (8 lb) lunch bags to shield against the “double whammy” of Pickle worm and the tropical Melon (Fruit)fly.

Fruit Fly Warfare

It isn’t my nature, but I have been slinking around like a true guerilla with my sites on the fruit fly population.  I wrote a 4 page essay on my findings, that I will spare you for now.  I will unleash it on my readers soon enough.  As some of you bundle up, and pour through your seed catalogs in hopes of Spring, perhaps dreaming about lands where there there is no true Winter, let me remind you, here in Hawaii we have the same brutal Agricultural pests as the Congo.  I wish I were joking.  One soon learns why 90% of our veggies are shipped in from Fruit fly free localities.  Here in Hawaii we are in the heart of yet another fruit fly “bloom” (they can have 8 to 9 cycles within the Calendar year. ) I refuse to be defeated.  Who knows, maybe outsmarting tropical pests will be my legacy.  It isn’t glamorous, but it is true.  OK back to the war…

Three waves of determined effort are necessary, and well, a continuous parts of your growing practice here in Alohaland.

Clean crop practice: I bag the stung squash in reused metallic coffee bags that my Starbuck’s Grounds for your Garden come in.  I then place them in the sun for a couple hours before they are dropped into a sealed bucket where they will die and decompose in the weeks again.

Lures:  The men are targeted and lured by the use of the right scent for the right fly ( sorry guys.)  Though Oriental Fruit fly does not attack squash, they are on the property in large numbers, so I am taking them out for the benefit of someone’s crops.  They may be feeding on a neighbor farm. The mean, but gorgeous Melon fly is my leopard spotted enemy.  Cure lure is their bait.  See reused cup trap image in prior post for the general idea.  Homemade traps have cleared hundreds of males from the two varieties, with the bulk being Oriental Fruit Fly.

Bag…no double bag ’em:  I have used my fledgling Blue Hubbard as a case study plant, trying out all kinds of strategies.  So far, my vote is for a quick, but meaningful hand pollination followed by a parafin wax baggie, topped with a brown paper lunch bag.  Driven by scent, this seems to be a good solution so far.
