Insect Feeding Assays with Spodoptera exigua on Arabidopsis thaliana

open access: yesBio-Protocol, 2020
Plant-insect interaction is an important field for studying plant immunity. The beet armyworm, Spodoptera exigua, is one of the best-known agricultural pest insects and is usually used to study plant interactions with chewing insects. Here, we describe a

Three Closely Related Spodoptera Species Similarly Affect Gene Expression and Phytohormone Levels but Differentially Induce Volatile Emissions in Maize. [PDF]

open access: yesPlant Cell Environ
ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.

Effect of Surfactants on Beet Armyworm and Fall Armyworm Larvae, 1994 [PDF]

open access: yesArthropod Management Tests, 1995
Abstract Six commercially-available surfactants/ wetting agents were compared to determine their toxic effects on beet armyworm and fall armyworm larvae. Larvae used in this study were obtained from the USDA-ARS Insect Biology and Population Management Research Lab in Tifton, GA, and were 4-days-old on the day of treatment.

Interactive Effects of Temperature and Plant Host on the Development Parameters of Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae)

open access: yesInsects, 2022
This study investigated the effects of different temperatures (15, 20, 25, 27, 30, 35, and 40 °C) on the development rate of Spodoptera exigua (Hübner) eggs, larvae, pupae, and total immatures on plant hosts (soybean, maize, potato, and green pea).

EFFECT OF MESSENGER-TREATED TOMATOES ON BEET ARMYWORM [PDF]

open access: yesArthropod Management Tests, 2002
Seedlings were transplanted in a sandy loam type soil on 12 Jun at the University of California's South Coast Research and Extension Center. Experimental plots were four rows wide (5-ft centers) by 40 ft long and separated by a 5-ft buffer. The tomato transplants were drip irrigated (water pH 7.2-7.5).

Control of Beet Armyworm and Southern Armyworm with Biological Insecticides on Bell Pepperfall 1993 [PDF]

open access: yesArthropod Management Tests, 1995
Abstract Seedlings of “Jupiter” bell peppers were transplanted on 1 Oct, 12 inches apart in single rows on raised beds covered with whitefaced polyethylene mulch and sub-surface irrigated. Beds had been prepared by fumigation with chloropicrin methyl bromide 33/67% 220 lbs/acre and fertilized with a bottom mix of 800 lbs/acre of 5-16-8 ...
