The booklice were adopted from China Agricultural University and identified by Dr.
For booklice, the contact toxicity was tested as described .
They could be some kind of mite or what are commonly known as booklice
George McGavin, curator of Entomology at Oxford University Museum, warns that plantations of so-called "terminator trees" would become biological deserts "with nothing but booklice
and earwigs." Environmentalists fear that living forests would be cleared to make room for Monsanto's Franken-firs.
The sections of the text are divided into Bristletails, Cockroaches, Crickets, Earwigs, Booklice
, Bugs, Beetles, Moths and butterflies, Ants, bees and wasps, and Flies.
The booklice Liposcelis bostrychophila Badonnel (Psocoptera: Lip oscelidae, LB) had strong adaptability to the environment and is resistant to harmful environmental conditions (tolerant to most insecticides or treatments and easy to recover populations) [24-28].
The assessment of the lethal (contact toxicity) and sublethal (repellent effects) of the EO and its main compounds is also needed to be tested to control booklice.
irritans fleas, trombiculid and mesostygmata mites, hard and soft ticks, and booklice
Arthropods covered by this hardback book include mites, cockroaches, thysanurans, mayflies, booklice
and barklice, thrips, twisted-wing parasites, true bugs, beetles, bees and wasps, butterflies, and flies.
During the screening program for new agrochemicals from Chinese medicinal herbs and wild plants, essential oil of Ageratum houstonianum (Family: Compositae) aerial parts was found to possess strong insecticidal toxicity against the booklice, Liposcelis bostrychophila Badonnel (Psocoptera: Liposcelidae).
The present research was therefore undertaken to investigate the chemical constituents and insecticidal and repellent activity of the essential oil against the booklice for the first time and to isolate active constituent compounds from the essential oil.
