Evaluation of predatory mite (Acari: Phytoseiidae) releases to suppress spruce spider mites, Oligonychus ununguis (Acari: Tetranychidae), on juniper.
A laboratory trial evaluated four phytoseiid species for their potential as biological control agents of spruce spider mite, Oligonychus ununguis (Jacobi) (Acari: Tetranychidae). An augmentative biological control approach, using the predatory mites Neoseiulus fallacis Garman and Galendromus occidentalis Nesbitt (Acari: Phytoseiidae), was evaluated for reducing pest mite densities and injury, a...
متن کاملBiology, Predation, and Life Table of Cydnoseius negevi and Neoseiulus barkeri (Acari: Phytoseiidae) on the Old World Date Mite, Oligonychus afrasiaticus (Acari: Tetranychidae)
The old world date mite, Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae) is a severe spider mite pest of date palm in most of the Middle East and North Africa. Considering that nothing is known about the performance of phytoseiid predators against O. afrasiaticus, biology, predation, and life table parameters of Cydnoseius negevi (Swirski and Amitai) and Neoseiulus barkeri Hughes (Ac...

متن کاملComparison of the susceptibility of several cultivars of avocado to the persea mite, Oligonychus perseae (Acari: Tetranychidae)
We compared the susceptibility of seven cultivars of avocado, Persea americana, to feeding by Oligonychus perseae. Based on the percentage of leaf area damaged by mites in February 1998, cultivars were categorized into three groups: Hass and Gwen were `susceptible', Fuerte, Lamb Hass and Reed were `resistant', Esther, and Pinkerton were of `intermediate' susceptibility. A life table study in th...
متن کاملDevelopment in Norway Spruce, Picea abies'
A pulse-treatment of embryos of Picea abies (L.) Karst with cytokinin efficiently and reproducibly induces the coordinate de novo formation of bud primordia from subepidermal cells. The cytokinin treatment also affects the germinative development of the embryo; chloroplast maturation is delayed, and cell elongation is completely suppressed. We have analyzed the protein patterns in developing sp...
