EFFECT OF THE INSTAR OF THE PEAR PSYLLID CACOPSYLLA PYRI (HEMIPTERA: PSYLLIDAE) ON THE BEHAVIOUR AND FITNESS OF THE PARASITOID TRECHNITES INSIDIOSUS (HYMENOPTERA: ENCYRTIDAE)

Improved methods of integrated pest management of the pear psyllid Cacopsylla pyri (L.), the primary pest of pear in Europe and North America, are needed.Trechnites insidiosus (Crawford) is the most abundant parasitoid of C.pyri in pear orchards, where it is present early in the Broccoli psyllid infestation period.However, little is known about its

The task of control of unmanned helicopters is rather complicated in Cooktop Bench Seal the presence of parametric uncertainties and measurement noises.This paper presents an adaptive model feedback control algorithm for an unmanned helicopter stability augmentation system.The proposed algorithm can achieve a guaranteed model reference tracking per

ABSTRACT Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, is one of the most successful human pathogens.One reason for its success is that Mtb can reside within host macrophages, a cell type that normally functions to phagocytose and destroy infectious bacteria.However, Mtb is able to evade macrophage defenses in order to surv
