Insecticidal soap is used to control many plant insect pests. Soap has been used for more than 200 years as an insect control. [1] Because insecticidal soap works on direct contact with pests via the disruption of cell membranes when the insect is penetrated with fatty acids, the insect's cells leak their contents causing the insect to dehydrate and die. [2]
There are three basic strategies for biological control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to ...
Extracts and purified chemicals from thousands of plants have been shown to be insecticidal, however only a few are used in agriculture. [49] In the USA 13 are registered for use, in the EU 6. In Korea, where it is easier to register botanical pesticides, 38 are used. Most used are neem oil, chenopodium, pyrethrins, and azadirachtin. [49]
In more recent times, bats are main characters in the children's book Stellaluna (1993) and the Silverwing series (1997 – 2007). [23] Bats in Chinese art: Desk Album- Flower and Bird Paintings (Bats, rocks, flowers oval calligraphy) by Zhang Ruoai, 18th century. Bats are a popular component of natural horror genre films and books.
Their insecticidal and insect-repellent properties have been known and used for thousands of years. Pyrethrins are gradually replacing organophosphates and organochlorides as the pesticides of choice as the latter compounds have been shown to have significant and persistent toxic effects to humans. They first appeared on markets in the 1900s ...

Bat flies are members of the insect order Diptera, the true flies, which are external parasites of bats. Two families of flies are exclusively bat flies: Nycteribiidae and Streblidae . [ 1 ] Bat flies have a cosmopolitan distribution, meaning that they are found around the world. [ 2 ]
Microbats constitute the suborder Microchiroptera within the order Chiroptera.Bats have long been differentiated into Megachiroptera (megabats) and Microchiroptera, based on their size, the use of echolocation by the Microchiroptera and other features; molecular evidence suggests a somewhat different subdivision, as the microbats have been shown to be a paraphyletic group.
