Effects of Low-Oxygen Environments on the Radiation Tolerance of the Cabbage Looper Moth (Lepidoptera: Noctuidae).

Ionizing radiation is used as a phytosanitary treatment to mitigate risks from invasive species associated with trade of fresh fruits and vegetables. Commodity producers prefer to irradiate fresh product stored in modified atmosphere packaging that increases shelf life and delays ripening. However, irradiating insects in low oxygen may increase radiation tolerance, and regulatory agencies are concerned modified atmosphere packaging will decrease efficacy of radiation doses.

Efficacy of attractive toxic sugar baits (ATSB) against Aedes albopictus with garlic oil encapsulated in beta-cyclodextrin as the active ingredient.

We tested the efficacy of attractive toxic sugar bait (ATSB) with garlic oil microencapsulated in beta-cyclodextrin as active ingredient against Aedes albopictus in suburban Haifa, Israel. Two three-acre gardens with high numbers of Ae. albopictus were selected for perimeter spray treatment with ATSB and ASB (bait containing no active ingredient).

Mi-1-Mediated Nematode Resistance in Tomatoes is Broken by Short-Term Heat Stress but Recovers Over Time.

Tomato (Solanum lycopersicum L.) is among the most valuable agricultural products, but Meloidogyne spp. (root-knot nematode) infestations result in serious crop losses.

Cell wall invertase-deficient miniature1 kernels have altered phytohormone levels.

The Zea mays (maize) miniature1 (Mn1) locus encodes the cell wall invertase INCW2, which is localized predominantly in the basal endosperm transfer layer (BETL) of developing kernels and catalyzes conversion of sucrose into glucose and fructose. Mutations in Mn1 result in numerous changes that include a small kernel phenotype resulting from both decreased cell size and number. To explore the pleiotropic effects of this mutation, we investigated the levels of indole-3-acetic acid (IAA), abscisic acid (ABA), salicylic acid (SA), and jasmonic acid (JA) in basal regions, upper regions, and embryos of developing kernels in the inbred line W22.

Sugar feeding by Culicoides mississippiensis (Diptera: Ceratopogonidae) on the yaupon holly, Ilex vomitoria.

Adult Culicoides mississippiensis Hoffman were collected from 5 flowering yaupon holly plants at sunrise, late morning, early afternoon, and sunset from 5 flowering yaupon holly plants during the entire flowering season (16 March-15 April 1995). Individual insects were tested for fructose by using the cold anthrone test. Prevalence of fructose in C.
