Summary of PRAGAS da JARDINAGEM que comem as FOLHAS das PLANTAS: lesma, lagarta, formiga

00:00:00 - 00:10:00

In the YouTube video "PRAGAS da JARDINAGEM que começam as FOLHAS das PLANTAS: lesma, lagarta, formiga," the speaker discusses various pests that damage plant leaves, focusing on the furrows or holes left behind. These pests include beetles, vaquinha, besourinhos metálicos, brocas marronzinhas, and snails. The size and appearance of the holes can help identify the culprit. For larger holes or tears, the speaker suggests looking for slime trails or the presence of mollusks. The speaker also distinguishes between lesmas, which are caused by various factors including insects and the weight of heavy leaves, and the mouths of insects. The speaker discusses the differences between damage caused by aphids, caterpillars, ants, and the Arapuá beetle, emphasizing the importance of understanding the types of damage to effectively address plant health issues.

• 00:00:00 In this section of the YouTube video titled "PRAGAS da JARDINAGEM que começam as FOLHAS das PLANTAS: lesma, lagarta, formiga," the speaker discusses the damage caused to plant leaves by various pests, specifically focusing on the furrows or holes left behind. The speaker explains that these furrows are often made by small creatures, such as beetles, which have a biting mouth and do not cause extensive damage. The speaker also mentions other pests, such as the vaquinha, besourinhos metálicos, and brocas marronzinhas, which also cause similar damage. The size and appearance of the holes can provide clues as to which pest is responsible. For larger holes or tears in the foliage, the speaker suggests looking for slime trails or the presence of mollusks, such as caramujos or caracóis, which can leave behind an esqueletizado or skeletonized appearance when they feed on the plant.
• 00:05:00 In this section of the YouTube video titled "PRAGAS da JARDINAGEM que começam as FOLHAS das PLANTAS: lesma, lagarta, formiga," the speaker discusses the difference between lesmas, which are not like ants or caterpillars with a mouth full of teeth, but rather have a rough tongue. The speaker then moves on to explain that when people begin to understand the logic of plants and learn to identify symptoms, they may become overly concerned and find "problems" everywhere. The speaker then describes a lesma made by a snail, which leaves small holes in the leaves, and notes that these holes can be an artwork in themselves. The speaker also mentions that sometimes the foliage of a plant can be damaged by something passing through it with force, causing the entire roll of the leaf (called a cartucho) to be ruined. Lesmas can be caused by various factors, including insects or the weight of heavy leaves or birds. The speaker also mentions that sometimes the damage is not caused by a single creature but a team of insects, with one specialist in boring into the cartucho and another in eating or damaging the foliage. The speaker then explains that the mouth of an insect and a lesma are not the same thing and provides an example of the anatomy of an ant's mouth.
• 00:10:00 In this section of the YouTube video titled "PRAGAS da JARDINAGEM que começam as FOLHAS das PLANTAS: lesma, lagarta, formiga," the speaker discusses various types of damage that can occur on plant leaves, specifically focusing on issues caused by insects such as aphids (lesma), caterpillars (lagarta), and ants (formiga). The speaker explains that while a green leaf may appear healthy, the backside may reveal damage from these pests. For example, aphids can be identified by their geometric or round patterns that destroy the foliage, often damaging the nervura of the leaf. Caterpillars, on the other hand, have a less potent bite than ants and tend to avoid the harder parts of the leaf, leaving behind a smaller amount of damage. The speaker also mentions that ants and caterpillars may work together on the same leaf, and that the difference in their biting styles can help distinguish between the two pests. The speaker also mentions the Arapuá beetle, which can cause damage that resembles holes but is actually caused by the beetle's mandibles. The speaker emphasizes the importance of understanding the difference between various types of damage to effectively address plant health issues.
