DOMINANT EGG SURFACE BACTERIA OF HOLOTRICHIA OBLITA (COLEOPTERA: SCARABAEIDAE) INHIBIT THE MULTIPLICATION OF BACILLUS THURINGIENSIS AND BEAUVERIA BASSIANA

Dominant egg surface bacteria of Holotrichia oblita (Coleoptera: Scarabaeidae) inhibit the multiplication of Bacillus thuringiensis and Beauveria bassiana

Abstract Holotrichia oblita (Coleoptera: Scarabaeidae) and some other scarab beetles are the main soil-dwelling pests in China.Bacillus thuringiensis (Bt) and Beauveria bassiana (Bb) are entomopathogens that have been used as biocontrol agents of various pests.However, scarab larvae especially H.oblita exhibited strong adaptability to these pathoge

Ionospheric control of space weather

As proposed by Saka (2019), plasma injections arising out of the auroral ionosphere (ionospheric injection) are a characteristic process of Wooden Jigsaw the polar ionosphere at substorm onset.The ionospheric injection is triggered by westward electric fields transmitted from the convection surge in the magnetosphere at field line dipolarization.Lo

One-dimensional time-Floquet photonic crystal

Using the Floquet Hamiltonian derived based on the time-dependent perturbation theory, we investigated the quasienergy bands of a one-dimensional time-Floquet photonic crystal (PC).The PC contains two alternating layers with different permittivies in the static case which are labeled as A and B.The permittivity of layer A is modulated periodically
