Abstract

A study was carried out to determine the preferences of rats in damaging pineapple MD2, based on hormonal induced days. Biologische Bundesantalt, Bundessortenamt and Chemische Industrie (BBCH) coding system, a phenology scale for all flowering plants, was used to describe the vegetative growth stage of MD2 pineapple in this study. The evaluation of MD2 phenology was carried out between 60 and 173 days after hormonal flower induction activity. Rat damage was studied at two growth stages, namely fruit development and fruit ripening of MD2 pineapple. The results showed that MD2 pineapple takes around 72 to 95 days to ripen from fruit development. The pineapple is best to be harvested around 140-145 days after hormonal flower induction activity or at BBCH scale 801-805. At this time, the pineapple turns from light green to yellowish green. Two species of rats, namely Rattus tiomanicus and Rattus argentiventer preferred matured fruits in between BBCH scales 800 to 805. Chemical control through rodenticide baiting campaign for rats needs to be done as early as 70-78 days after hormonal flower induction activity or before the BBCH scale 700 as best control measures. Keywords: Biologische Bundesantalt, Bundessortenamt and Chemische Industrie coding system, pineapple, rat damage.

基于激素致花天数和物候的菠萝md2损伤大鼠果实发育、成熟及偏好观察

一项研究是根据激素诱导的天数来确定大鼠在破坏菠萝MD2时的偏好。本研究采用Biologische Bundesantalt, Bundessortenamt和Chemische Industrie (BBCH)编码系统作为所有开花植物的物候尺度来描述MD2菠萝的营养生长阶段。在激素诱导花后60 ~ 173天进行MD2物候学评价。研究了MD2菠萝果实发育和成熟两个生长阶段的大鼠损伤。结果表明，MD2菠萝从果实发育到成熟大约需要72 ~ 95天。菠萝最好在激素诱导花活动后140-145天左右或BBCH尺度801-805收获。这时，菠萝从浅绿色变成了黄绿色。田鼠(Rattus tiomanicus)和阿根廷田鼠(Rattus argentiventer)两种大鼠偏爱BBCH尺度800 ~ 805之间的成熟果实。最好的防治措施是在激素诱导花活动后70-78天，或在BBCH量表700之前进行化学防治。关键词:联邦生物，联邦政府和化学工业编码系统，菠萝，鼠害
