Honeydew is a source of attraction for the sooty mold fungus. Aphids can pose a threat to small trees, but they are considered minor pests.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%D8%A3%D8%B9%D8%B1%D8%A7%D8%B6_%D9%85%D8%B1%D8%B6_%D8%A7%D9%84%D9%85%D9%86_%D8%A7%D9%84%D8%A7%D8%B3%D9%88%D8%AF_%D8%B9%D9%84%D9%89_%D8%A7%D9%88%D8%B1%D8%A7%D9%82_%D8%A7%D9%84%D9%84%D9%8A%D9%85%D9%88%D9%86\"><\/span><strong>Symptoms of black aphid disease on lemon leaves<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Tree aphids suck the sap from the leaves, causing the leaves to become wrinkled, twisted, and yellow in color, giving the infected leaves a distorted appearance. As the severity of the infestation increases, leaves fall and the death of twigs and branches can be observed. Honeydew also attracts a number of insects, the most important of which are ants.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%D8%AF%D9%88%D8%B1%D8%A9_%D8%AA%D8%B7%D9%88%D8%B1_%D9%85%D8%B1%D8%B6_%D8%A7%D9%84%D9%85%D9%86_%D8%A7%D9%84%D8%A7%D8%B3%D9%88%D8%AF_%D8%B9%D9%84%D9%89_%D8%A7%D9%88%D8%B1%D8%A7%D9%82_%D8%A7%D9%84%D9%84%D9%8A%D9%85%D9%88%D9%86\"><\/span><strong>Development cycle of black aphid disease on lemon leaves<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Females do not need to mate to produce young and do not lay eggs.
