An individual mosquito can be heard across 2–5 cm in distance when sound level rises to 22-25 dB. [7] Male and female mosquitoes can also be distinguished by their wingbeat frequencies, which are 700–800 Hz for males and 400–500 Hz for females. [7] As a result, flight sounds are used to determine flight activity and distinguish sex of groups.
When applied in fall and winter, mulches delay the growth of perennial plants in the spring and prevent growth in winter during warm spells, thus limiting freeze–thaw damage. [10] The effect of mulch upon soil moisture content is complex. Mulch forms a layer between the soil and the atmosphere reducing evaporation. [11]

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 ...
The best way to avoid mosquito bites is to use bug sprays with DEET. The CDC also recommends Picaridin (known as KBR 3023 and icaridin outside the U.S.). The sprays won’t kill the bugs, but they ...
Some cover crops are used as so-called "trap crops", to attract pests away from the crop of value and toward what the pest sees as a more favorable habitat. [44] Trap crop areas can be established within crops, within farms, or within landscapes. In many cases, the trap crop is grown during the same season as the food crop being produced.
A layer (around 10 cm thick) of weed-free soil, rich in nutrients is added, in an attempt to mimic the surface soil, or A horizon. [4] A layer (at most 15 cm thick) of weed-free, woody and leafy matter is added in an attempt to mimic the forest floor, or O horizon. Theoretically, the soil is now ready to receive the desirable plant seeds or ...
