Evaluation of new strain (AAD16) of Beauveria bassiana recovered from Japanese rhinoceros beetle: Effects on three coleopteran insects.

A strain (AAD16) of the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin was isolated from field-collected Japanese rhinoceros beetle, Allomyrina dichotoma (L.) (Coleoptera: Scarabaeidae). Its virulence was compared with another strain (ARP14) recovered from a cadaver of Riptortus pedestris (F.

Synergism of a mixed diet of Myzus persicae and egg of Ephestia kuehniella on fitness of the predator Nabis stenoferus.

Nabis stenoferus is a zoophytophagous predator that lives in grasslands around agricultural fields. It is a candidate biological control agent for use via augmentation or conservation. To find a suitable food source for mass-rearing and to better understand this predator's biology, we compared the life history characteristics of N.

Puncturing apple fruits increases survival of Grapholita molesta (Lepidoptera: Tortricidae) in laboratory rearing.

Grapholita molesta (Busck) is a major pest in orchards of apple, peach, and plum. For better rearing in the laboratory, we compared the life history characteristics of G. molesta by providing larvae with either punctured or unpunctured apple fruits.

Developmental stages of peach, plum, and apple fruit influence development and fecundity of Grapholita molesta (Lepidoptera: Tortricidae).

Host plant attributes are essential factors determining the population dynamics of herbivorous insects. The developmental stage of host plants, in particular, may affect the biology of Grapholita molesta (Busck), a possibility that has rarely been examined. Here we assessed the effect of developmental stage of plum, peach, and apple fruits on the development and fecundity performance of G.

Laboratory Evaluation of Beauveria bassiana ARP14 Against Grapholita molesta (Lepidoptera: Tortricidae).

Entomopathogenic fungi often have wide host range and can be important biological control agents against the oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae), a significant pest of stone and pome fruits. The virulence of six entomopathogenic fungi, including three strains of Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae) (ARP14, GHA, A) and one strain each of Metarhizium robertsii Bischoff, Rehner, & Humber (Hypocreales: Clavicipitaceae), Metarhizium brunneum (Petch) (Hypocreales: Clavicipitaceae), and Isaria farinosa (Holmsk.) (Hypocreales: Cordycipitaceae) was assessed against first instars (< 5 h old) of G.

Development and Fecundity of Orius minutus (Hemiptera: Anthocoridae) and O. laevigatus Reared on Tetranychus urticae (Acari: Tetranychidae).

The polyphagous predator Orius species is a dominant predator of thrips, mites, and aphids. Orius laevigatus (Fieber) is a well-known commercialized and effective biological control agent, whereas Orius minutus (L.) distributed widely over the world has not been commercialized.

Development and fecundity performance of Grapholita molesta and Grapholita dimorpha (Lepidoptera: Tortricidae) on different immature fruits.

Both Grapholita molesta (Busck) and Grapholita dimorpha Komai (Lepidoptera: Tortricidae) are important pests of pome and stone fruits. Mature fruits of peach and plum have been tested as food sources for G. molesta, but no studies have examined the suitability of immature fruits, which are the fruit stage more likely to be available for the spring populations of both G.

Extract of Nicotiana tabacum as a potential control agent of Grapholita molesta (Lepidoptera: Tortricidae).

Oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae), is an important pest of stone and pome fruits. Growers usually depend on chemical insecticides to control this pest, but demand for more environmentally-friendly means of controlling pests is increasing. At least 91 plant extracts have been reported to be effective against other lepidopterans, but their acute toxicity against G.
