Selection of Isolates of Entomopathogenic Fungi and the Bioefficacy of Their Liquid Production against Leptocorisa oratorius Nymphs
Entomopathogenic fungi are fungi pathogenic to insects and are widely used as biocontrol agents for insect pests. The aim of this research was to study the virulence of Beauveria bassiana and Metarhizium sp. isolates and to evaluate the efficacy of liquid production of those fungi against Leptocorisa oratorius (rice bug). Twelve isolates of B. bassiana and five isolates of Metarhizium sp. were ...
متن کاملDi f ferent Surface Treatments
submitted to different surface treatments. Forty-eight maxillary canines had their crowns sectioned and root canals endodontically treated. The roots were embedded in acrylic resin and distributed into 3 groups according to the surface treatment: Group I: the posts were treated with silane agent for 30 s and adhesive; Group II: the posts were cleaned with alcohol before treatment with silane ag...
متن کاملGenetic Diversity and Host Alternation of the Egg Parasitoid Ooencyrtus pityocampae between the Pine Processionary Moth and the Caper Bug
The increased use of molecular tools for species identification in recent decades revealed that each of many apparently generalist parasitoids are actually a complex of morphologically similar congeners, most of which have a rather narrow host range. Ooencyrtus pityocampae (OP), an important egg parasitoid of the pine processionary moth (PPM), is considered a generalist parasitoid. OP emerges f...
متن کاملOverlapped Di-tone Modeling f Continuous Canton
This paper presents a novel approach to tone recognition in continuous Cantonese speech based on overlapped di-tone Gaussian mixture models (ODGMM). The ODGMM is designed with special consideration on the fact that Cantonese tone identification relies more on the relative pitch level than on the pitch contour. A di-tone unit covers a group of two consecutive tone occurrences. The tone sequence ...
متن کاملAn Old Remedy for a New Problem? Identification of Ooencyrtus kuvanae (Hymenoptera: Encyrtidae), an Egg Parasitoid of Lycorma delicatula (Hemiptera: Fulgoridae) in North America
Spotted Lanternfly, Lycorma delicatula (White) is a recently introduced pest of Tree-of-Heaven, Ailanthus altissima (Mill.) Swingle in North America. Natural enemy surveys for this pest in Pennsylvania in 2016 recovered an encyrtid egg parasitoid from both field collections and laboratory rearing of field-collected L. delicatula egg masses. Both molecular and morphological data confirm that the...
