冬季方法,植物移动室内,突然你发现自己被各种形状大小的植物所吞没。除空间外,保持植物室内不难。植物生长会减光减温缓慢,但在引进植物时常常忽略昆虫问题。了解并识别潜在的昆虫从长到长会帮助防止植物健康在泉水到来前下坡

Herbs such as rosemary, sage, thyme, and spearmint are food to a few different insects.  The insects most likely to be encountered on these plants include two spotted spider mite (Tetranychus urticae), sage leafhopper (Eupteryx melissae), and spittlebugs (Cercopidae).   Although common, these insects often go unnoticed due to their small size and where they reside on the plant (underneath the leaves).  Plants should be inspected upon entry so that a large population won't thrive undetected and affect ornamental plant health.  Each one of the insects listed can be treated with horticulture oil, or a homemade 2% solution of oil with warm soapy water.  It is advised to test your solution on part of the plant to prevent any phytotoxicity before application is made to the entire plant.  The spray should cause the foliage to be wet, but not have runoff.

Citrus plants will involve mostly sap sucking insects such as brown citrus aphids (Toxoptera citricida), hemispherical scale (Saisettia coffae), black scale (saissetia oleae), and citrus mealybug (Planoccoccus citri).  These insects latch onto the plant and feed by inserting their mouth parts into the plant cells, leading to lack of vigor, leaf curl, and stunting.  A byproduct of these insects feeding, called honeydew, can lead to black sooty mold forming.  Beneficial insects such as ladybeetle larvae can serve as a biological control in addition to Cryptolaemus larvae.  Beneficial use is more difficult during winter months for various reasons, so manually removing pests in addition to applying any oils previously mentioned above are a good plan of attack.  Stay vigilant and look for these insects shown below.
