吊死鬼(吊死鬼)

吊死鬼”平常是呆在樹上的，未老熟前不能吐絲。但是到能吐絲了以后，它們并不立即鉆入土中化蛹，還會在樹上呆一段時間，這時它們一旦受驚就會采取自我保護的措施——吐絲把自己懸在空中，脫離樹枝。

一般突然來的大風吹過樹的時候就會有不少“吊死鬼”垂下來。 另外，說明一點，它們入土化蛹的時候，并不是從樹上垂下來的，而是直接爬到地面上去。 以下，尺蠖資料。 尺蠖（chihuo）無脊椎動物，昆蟲綱，鱗翅目，尺蛾科昆蟲的統稱。幼蟲身體細長，行動時一屈一伸像個拱橋，休息時，身體能斜向伸直如枝狀。完全變態。成蟲翅大，體細長有短毛，觸角絲狀或羽狀，稱為“尺蛾”。全世界約有12000種，我國約有43種。幼蟲危害果樹，茶樹、桑樹、棉花和林木等。如茶尺蠖的幼蟲食害葉片，嚴重時造成光禿現象。靜止時，常用腹足和尾足抓住茶枝，使蟲體向前斜伸，頗像一個枯枝，受驚時即吐絲下垂；又如棗尺蠖的幼蟲，不僅食害棗樹，酸棗的'葉片，并食嫩芽、花蕾，造成嚴重危害。雌成蟲無翅，雄成蟲全體灰褐色，前翅有褐色波紋2條。我國南北各地最常見的桑尺蠖，其幼蟲常作為“擬態”的典型代表。 生活史及習性： 每年發生1代，以蛹在樹下土中8～10厘米處越冬。翌年3月下旬至4月上旬羽化。雌蛾出土后，當晚爬至樹上交尾，卵多產在樹皮縫內，卵塊上覆蓋有雌蛾尾端絨毛。4月中下旬棗樹發芽，幼蟲孵化為害，為害盛期在5月份。5月下旬至6月上旬幼蟲先后老熟，入土化蛹越夏越冬。 天敵: 有棗尺蠖腫跗姬蜂和寄生蠅。

1.成蟲羽化前，在樹干基部挖蛹。 2.在樹干綁15厘米寬的塑料薄膜帶，然后集中捕殺。 3.在卵基本孵化結束時，噴灑有機磷殺蟲劑或菊酯類殺蟲劑。

吊死鬼游戲 Hangman (game) Hangman is a paper and pencil guessing game for two players. One player thinks of a word and the other tries to guess it by suggesting letters. The word to guess is represented by a row of dashes, giving the number of letters. If the guessing player suggests a letter which occurs in the word, the other player writes it in all its correct positions. If the suggested letter does not occur in the word, the other player draws one element of the hangman diagram. The game is over when: The guessing player completes the word, or guesses the whole word correctly The other player completes the diagram: This diagram is, in fact, designed to look like a hanging man. Although debates have arisen about the questionable taste of this picture, it is still in use today. The exact nature of the diagram differs; some players draw the gallows before play and draw parts of the man's body (traditionally the head, then the torso, then the left arm, then the right arm, then the left leg, then the right leg). Some players begin with no diagram at all, and drawing the individual elements of the gallows as part of the game, effectively giving the guessing players more chances. Some modifications to game play, such as "'buying' a vowel" and the "RSTLNE" common letter use result from the U.S. television game show Wheel of Fortune, created by Merv Griffin. Hangman is sometimes played as a forum game.
