to start talk to you about today is the trap. What to do and then what to look for in the

今天要開始跟大家說的是陷阱。該怎麼做，然後要注意什麼呢？

fruit.

果。

First, let's look at a trap. Let's take the top off this trap. This has been out here

首先，讓我們看看一個陷阱。讓我們把這個陷阱的頂部拿掉。這東西一直在這裡

for about a week. As you take the top off the trap with the bait, you can zero in here,

大約一個星期。當你把頂部關閉陷阱與誘餌， 你可以在這裡歸零。

and there are many, probably right now I can see about 25, small flies floating on the

有很多，可能現在我可以看到大約25， 小蒼蠅漂浮在上的

top of this trap. You can look down and you can see the spots on the wing of the male.

這個陷阱的頂部。你可以往下看，你可以看到 男性的翅膀上的斑點。

Again, that's the male spotted wing drosophila. The females have a tendency to either float

同樣，那是雄性斑翅果蠅。雌性有一種傾向，要麼浮動

or, when they sink, their ovipositor, which is what they use to lay eggs with, actually

或者，當它們下沉時，它們的產卵器，也就是它們用來產卵的東西，實際上是

becomes overted and you can see that, so it's easy to tell the males and the females in

變得過度了，你可以看到，所以它很容易告訴男性和女性在

here. The females do not have the spot on the wing.

這裡。雌性的翅膀上沒有斑點。

You've got your traps out, and you've started finding spotted wing drosophila in your traps.

你'了你的陷阱，你'已經開始發現斑翅果蠅在你的陷阱。

The concern now becomes, what's happening to the fruit? We have been finding, here in

現在關心的是，果實發生了什麼'？我們已經發現，在這裡

Maine this year, which is 2012, we found maggots or flies, so far, in raspberries, blackberries,

緬因州今年，也就是2012年，我們發現了蛆或蒼蠅，到目前為止，在樹莓、黑莓。

blueberries, elderberry, grapes, chokecherry, and peaches. Traditionally, the fruit flies

藍莓、接骨木、葡萄、櫻桃和桃子。傳統上，果蠅

that we have, would come to the overripe fruit. Their ovipositor, which is what they lay their

我們所擁有的，會來到過熟的水果。它們的產卵器，也就是它們的產卵器。

eggs with, it's not serrated. It doesn't have that little saw-like on it, so it has to be

雞蛋與，它'不是鋸齒。它不'有那個小鋸子一樣就可以了，所以它必須是

very, very soft fruit for them to lay an egg in.

非常，非常柔軟的水果，讓他們下蛋。

But this one, now, with this serrated ovipositor, can actually lay the eggs in fruit like this,

但現在這個，有了這個鋸齒狀的產卵器，居然可以像這樣在水果裡產卵。

or even like this. Once you get fruit like this attacked, it doesn't take long before

甚至像這樣。一旦被這樣的果實攻擊，不用多久就會被

it starts to shrivel up. Let's see what's happening here with the fruit. We'll pull

它開始萎縮。讓我們看看這裡發生了什麼'與水果。我們會拉

some off, take a look at it. This is what's happening. You see, when you pull that fruit

一些關，看看它。這是什麼'的發生。你看，當你拉那個水果

off too, it almost looks bubbly in there, almost like there was a detergent in there.

掉了，裡面幾乎看起來是泡沫狀的，幾乎就像有一個洗滌劑在裡面。

That's because the fruit has started to be eaten by the maggots. Once it's being eaten

那是因為水果已經開始被蛆蟲吃掉了。一旦它被吃掉

by the maggots, it gets real juicy.

由蛆蟲，它得到真正的多汁。

In this particular berry, just looking here, as I move this apart with the pen I can probably

在這個特殊的漿果，只是在這裡看，當我移動這個分開用筆，我可以大概。

see at least a half a dozen or a dozen maggots, right in this area. Part of the problem is,

看到至少有半打或十幾只蛆，就在這個區域。部分問題是。

with this pest, when you go out and you pick your fruit, it looks great on the vine or

有了這種害蟲，當你出去採摘你的水果，它看起來很不錯的藤或

on the bush. Within a matter of maybe 24 hours with raspberries, or two or three days with

在灌木叢中。也許在24小時內，覆盆子，或兩三天內，與

blueberries, they just start to turn to liquid.

藍莓，它們剛開始變成液體。

You can actually see some maggots crawling on the fruit, but even worse, you can see

in this box where it's actually started to liquefy. The box has soaked it all up, but

在這個盒子裡，它實際上開始液化。盒子已經把它全部浸透了，但是... ...

on the outside of the box you've got all these maggots crawling around. These are about a

在盒子的外面，你'已經得到了所有這些蛆蟲爬來爬去。這些是關於一個

week old, on the blueberries. Now, the raspberries, these were nice, fine-looking raspberries

一週大的藍莓。現在，覆盆子，這些都是漂亮的，好看的覆盆子。

just completely, as I say, turned to mush.

就像我說的，完全變成了肉泥。

The problem comes within a minimum, this time of year, in the summer, a minimum of 14 days

問題的出現在最短的時間內，這個時候，在夏天，最少要14天

and maybe even as quick as 10 days, the fly can go from egg to adult. It's a real fast

甚至可能快到10天，蒼蠅可以從卵到成蟲。這是一個真正的快速

critter, so that's going to give us real problems with trying to manage this particular pest.

小動物，所以'將給我們真正的問題 試圖管理這個特殊的害蟲。
