Palmetto weevil grubs infesting a Bismarck palm. The palmetto weevil (Rhynchophorus cruentatus) is an insect native to Florida, but has been found as far as southern Texas to the west and South Carolina to the north. [1] [2] It is the largest weevil in North America and the only kind of palm weevil in the continental United States. [1]
Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
In late autumn and during winter, they retreat down from the top 5 cm of soil and burrow down between 50–200 mm into the soil. During this phase, the grubs undergo a colour change from grayish/white into a yellow/cream colour. Once they reach the appropriate depth, the grub empties its stomach and starts to form a smooth oval shaped cell.
During spring and summer, it often seems like your lawn can't get enough water. But once winter temperatures arrive and your landscape quiets down for the season, you may not even think about ...
A common sign of skunks is the presence of 1 to 3-inch cone-shaped holes all over your lawn where skunks have foraged for grubs and worms. They are nocturnal but will occasionally forage in ...
The fly larvae feed on the beetle grub in the ground and pupate in the grub cell where they stay over the winter. [4] Wasps in numerous families, including Pelecinidae, Scoliidae, and Tiphiidae, are parasitoids of Phyllophaga grubs. A variety of amphibians, some small mammals, including skunks and moles, feed on the grubs.
Winter is a time when plants are often dormant, and missteps can lead to more harm than good, says Ponce. “A common mistake, for instance, is overwatering,” he adds.
Chemical treatment on dormant plants has been proven to be an effective method to break dormancy, particularly in woody plants such as grapes, berries, apples, peaches, and kiwis. Specifically, hydrogen cyanamide stimulates cell division and growth in dormant plants, causing buds to break when the plant is on the edge of breaking dormancy.
