Question

蝗蟲(chóng)的個(gè)體發(fā)育要經(jīng)過(guò)________、________、________三個(gè)時(shí)期．

Answer 1

受精卵    幼蟲(chóng)    成蟲(chóng)
分析：此題是一道基礎(chǔ)知識(shí)題，具體考查的是昆蟲(chóng)的發(fā)育過(guò)程．昆蟲(chóng)的發(fā)育分為不完全變態(tài)和完全變態(tài)兩種．不完全變態(tài)發(fā)育過(guò)程要經(jīng)過(guò)受精卵、幼蟲(chóng)和成蟲(chóng)三個(gè)時(shí)期；完全變態(tài)發(fā)育過(guò)程要經(jīng)過(guò)受精卵、幼蟲(chóng)、蛹和成蟲(chóng)四個(gè)時(shí)期．
解答：昆蟲(chóng)的發(fā)育分為不完全變態(tài)和完全變態(tài)兩種．不完全變態(tài)發(fā)育過(guò)程要經(jīng)過(guò)受精卵、幼蟲(chóng)和成蟲(chóng)三個(gè)時(shí)期；完全變態(tài)發(fā)育過(guò)程要經(jīng)過(guò)受精卵、幼蟲(chóng)、蛹和成蟲(chóng)四個(gè)時(shí)期．蝗蟲(chóng)的個(gè)體發(fā)育屬于不完全變態(tài)，所以要經(jīng)過(guò)受精卵、幼蟲(chóng)和成蟲(chóng)三個(gè)時(shí)期．
故答案為：受精卵 幼蟲(chóng) 成蟲(chóng)．
點(diǎn)評(píng)：昆蟲(chóng)的生殖和發(fā)育過(guò)程是重要的知識(shí)點(diǎn)和考點(diǎn)．
