Response of Caterpillar Pests and the Parasite Diadegma insulare to Collard Cultivars and a Pyrethrin Insecticide
Autor: B.M. Shepard, K.A. Stoner, J. M. Schalk
Publikováno v: HortScience. 28:308-310
There were no differences in mortality, plant preference, or plant damage when diamondback moth (DBM) (Plutella xylostella L.) larvae were tested in no-choice and free-choice tests using leaf disks of resistant (`Green Glaze') or susceptible (`Vates'

Responses of Soil Insects to Mixed and Contiguous Plantings of Resistant and Susceptible Sweetpotato Cultivars
Autor: Kenneth P. Burnham, Philip D. Dukes, J. M. Schalk, Alfred Jones
Publikováno v: HortScience. 27:1089-1091
This study was designed to determine if the preference of soil insects for sweetpotato (Ipomoea batatas (L.) Lam.) cultivars is affected by the proximity of re- sistant or susceptible plant cultivars at various spacings. Comparisons were made for dam

Evaluation of Sweetpotato Clones for Soil Insect Damage
Autor: Philip D. Dukes, Alfred Jones, J. M. Schalk, Robert L. Jarret
Publikováno v: HortScience. 26:1548-1549
The reactions of eight sweetpotato [Ipomoea batatas (L.) Lam.] introductions were categorized for root damage by wireworms, Diabrotica sp., Systena sp. (WDS), sweetpotato flea beetle (SPFB), and grubs. Clones were compared with resistant (`Regal') an

Resistance in Pepper (Capsicum annuum L.) to Western Flower Thrips [Frankliniella occidentalis (Pergande)]
Autor: J. M. Schalk, Richard L. Fery
Publikováno v: HortScience. 26:1073-1074
A replicated greenhouse study was conducted to confirm the availability of resistance to western Rower thrips in pepper germplasm. Host-plant resistance ratings confirmed earlier observations that there is a considerable amount of variability within

BREEDING FOR INSECT RESISTANCE IN SWEETPOTATO
Autor: J. R. Bohac, P.D. Dukes, J. M. Schalk
Publikováno v: HortScience. 29:726e-726
A two year study was conducted to evaluate the efficacy of insect resistance in sweetpotato cultivars from our breeding program in combination with an insecticide (fonofos) and/or a parasitic nematode (Steinernema carpocapsae). In the laboratory, use
