The eggs hatch soon afterwards and in this larval or grub stage, they feed on the roots of grass and other plants. As the weather gets cooler and winter approaches, the grubs go deeper into the soil, and feeding declines as they over-winter. In August, when the grubs are close to the surface and feeding, they are vulnerable to infestation by ...
The grubs sometimes attack vegetables and other garden plants, e.g. lettuce, raspberries, strawberries, potatoes, and young ornamental trees. Injury to the roots and rootstock causes small saplings and tender tap-rooted plants like lettuce to wilt suddenly or to show stunted growth and a tendency to shed leaves prematurely.
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.
A large lizard, known as the tegu, has started to take root in Tampa, Florida. But it's not supposed to be. The reptile, native to South America, has become a popular exotic pet amongst Floridians ...
Native plants and animals in Florida are threatened by the spread of invasive species. [2] Florida is a major biodiversity hotspot in North America and the hospitable sub-tropical climate has also become a hotspot for invasive plants and animals due to anthropogenic introduction. [3] [4]
Holotrichia is a genus of beetle in the family Scarabaeidae, which are well known as "chafer beetles" or "white-grubs" for their white larvae that are found under the soil where they feed on the roots of plants.
What we do know is that the four-leaf clover has been a symbol of luck for centuries. Just to name a few examples, it's mentioned in a book from the 1600s, it was carried as soldier's good-luck ...
Grubs also can be removed from the cultivation land by cultural practises such as ploughing, harrowing, hoeing, flooding and fallowing of fields, trap cropping and crop rotation. Other than that, resistant crops such as sunflower and trap crops such as sorghum, maize, onion can be grown along with the cultivation.
