1. 蚜虫腹部有管状突起(腹管)，蚜虫具有一对腹管，用于排出可迅速硬化的防御液，成份为甘油三酸脂，腹管通常管状，长常大于宽，基部粗，吸食植物汁液，为植物大害虫。不仅阻碍植物生长，形成虫瘿，传布病毒，而且造成花、叶、芽畸形。生活史复杂，无翅雌虫在夏季营孤雌生殖，卵胎生，产幼蚜。植株上的蚜虫过密时，有的长出两对大型膜质翅，寻找新宿主。夏末出现雌蚜虫和雄蚜虫，交配后，雌蚜虫产卵，以卵越冬，最终产生干母。温暖地区可无卵期。蚜虫有蜡腺分泌物，所以许多蚜虫外表像白羊毛球。

1. The aphid's abdomen has tubular projections (siphunculi), with each aphid having a pair of siphunculi, which are used to expel a defensive fluid that hardens quickly. The fluid consists of triglycerides, and the siphunculi are usually tubular, with the length often greater than the width, a thick base, and they feed on plant sap, making them a major pest to plants. They not only hinder plant growth and cause galls, spread viruses, but also lead to malformations in flowers, leaves, and buds. Their life cycle is complex; wingless females reproduce parthenogenetically in summer, giving birth to nymphs. When aphids become too dense on a plant, some develop two pairs of large membranous wings to find new hosts. Towards the end of summer, female and male aphids appear, mate, and the female aphids lay eggs, overwintering as eggs and eventually producing dry mother aphids. In warm regions, there may be no egg-laying period. Aphids have wax glands, which is why many of them look like white wool balls.

2. 是的，这样更容易把茶碱煮到水中。不然的话效果不好。茶碱不利于蚜虫繁殖。茶的气味会驱赶蚜虫。不如开那就多泡几天。用碱面水也行，但是浓度别太高，以免对花不好。要区分对待，不同的花招了蚜虫对待方法不一样。因为有的花喜碱性，有的喜酸性，浓度过高或进入土中会影响花的生长。

2. Yes, it's easier to boil theophylline into the water this way. Otherwise, the effect is not good. Theophylline is not conducive to the reproduction of aphids. The smell of tea can drive away aphids. If not, it's better to steep it for a few more days. You can also use water with baking soda, but don't make it too concentrated, as it may not be good for the flowers. You need to treat them differently; different flowers have different methods of dealing with aphids. Because some flowers like an alkaline environment, while others prefer an acidic one; too high a concentration or getting into the soil can affect the growth of the flowers.
