Although cereal grains are the preferred food plants of the cereal leaf beetle, Oulema melanopus (L.), several other graminoid species are acceptable feeding hosts of larvae and adults of this chrysomelid beetle. In view of the potential for expandin

Beet armyworm, Spodoptera exigua (Hubner), is an economic pest of chickpea, Cicer arietinum L., in Mexico and the Indian subcontinent. Larvae feed on the vegetative and reproductive stages of chickpea and the development of plant resistance is a prio

The pea weevil, Bruchus pisorum (L.), is one of the most intractable pest problems of cultivated pea, Pisum sativum L., in the world. This study investigated the transfer of pea weevil resistance from two accessions (PI 595946, PI 343955) of wild pea

This research quantified frequencies of Neotyphodium infected (E+) tillers and mature seed from field-grown E+ plants of two wild tall fescue accessions from Morocco and Sardinia, Italy. Tiller infection rates were 100% (n = 50 from 10 E+ plants/acce

The extent of Neotyphodium based resistance in wild fescue to bird cherry-oat aphid (Rhopalosiphum padi) was determined by quantifying densities of this aphid on a series of Neotyphodiuminfected (E+) and uninfected (E-) tall fescue entries. Little or

Neotyphodium (Clavicipitaceae: Balansieae) fungal endophyte infection does not always confer temperate grass resistance to insect herbivores, although reports indicate that over 40 species are adversely affected by its infection. Laboratory and glass

A 5 yr study in the semiarid wheat production region of eastern Washington documented the relative densities of pest aphids and their natural enemies in cereal production systems using on-farm replicated plots. The systems were reduced-tillage soft w
