Abstract
木瓜赤圓介殼蟲,Aonidiella inornata MIckenzi,由高橋良一在關子嶺及恒春於木瓜上發現。嗣後本省即無有關該蟲之文獻發表。
最近數年來,日陞(Sunrise Solo)及高寶(Kapoho Solo)二新品種木瓜在本省南部推廣之後,普遍遺受該蟲為害。該蟲附在木瓜主幹和其果實表面,吸收其液汁,嚴重影響木瓜發育,不但產量減低,亦失去市場價值。被害木瓜植株衰弱,有些丙原菌易從蟲。刺傷之部位侵入,致主幹枯腐而折斷。
該蟲於木貝開花結實時開始在主幹為害,遲漸蔓延至果實,故在木瓜生育之盛期切發生最多,至後期由於木瓜之生育因被害而停滯,復其主幹表面已佈滿介殼蟲之軀殼和其分泌物,使若蟲無立足之地,因充其密度逐慚減低。
四種段蟲劑對該害蟲有良好防洽效果,即減大松40%乳劑0.05%,馬拉松50%乳劑0.10%,福木松33%乳劑0.05%和大滅松44%乳劑0.05%,在介殼蟲發生初期每10天噴一次,連續兩次便可完全防治。
Papiya red scale, Aonidiejje inornata Mckenzic, has been found injuring papaya in southern part of Taiwan by Takahashi since 1939. But there was not any paper dealing with this pest after the world war II.
This scale has become aburkdant in recent years on the new varieties of papaya, Sunrise Solo and Kapoho Solo, which were introduced from Hawaii in 1967. The scale insect was firstly found damaging on the pseudostem of papaya on which the small fruits were about bearing, and then spreading out on the whole surface of the pseuodstem and the fruits. As a result, they reduced the market value of the fruits, and weakened the vigor of the trees and finally caused the trees to be snapped in the midIle of the trunk.
The occurrence of the scales was closely associated with the vigor of the papaya especially the crawlers of the scale, which appeared more abundant during the stage when the fruits of papaya were settings but reduced in numbers gradully as the surface of the pseudostem was all occupied by the dead bodies and the secretion of the scales.
Four insecticides were tested to be effective. These were Supracide 40% EC 0.05 %, Malathion5 0% EC 0.10%. Anthio 33% EC 0.05% and Demethoate 44% EC 0.05%. They must be applied at the beginning of the establishment of the scales. Two applications at 10 day intervals would give satisfactory control.
