Intermediates in the Transformation of Phosphonates to Phosphate by Bacteria
The elucidation of the chemical steps for the biodegradation of alkylphosphonates shows how these compounds can be metabolized and recycled to phosphate. Expand
Floral Lipid Chemistry of Byrsonima crassifolia (Malpigheaceae) and a Use of Floral Lipids by Centris Bees (Hymenoptera: Apidae)
Oil collected from the scopae of two representative Centris species was the same as the type one oil collected from B. crassifolia type one floral elaiophore oil with the exception of several minor ninhydrin positive compounds which may have been derived from the pollen which makes up part of the larval food provisions.

Influence of host plant on mate location by the parasitoid Campoletis sonorensis (Hymenoptera: Ichneumonidae)
In wind tunnel flight tests, only 13% of male Campoletis sonorensis (Cameron) located a female in the absence of a cotton plant, whereas 63% of males located a female placed on a leaf of a cottonExpand
Dominicalure 1 and 2: Components of aggregation pheromone from male lesser grain borerRhyzopertha dominica (F.) (Coleoptera: Bostrichidae)
Volatiles from lesser grain borers,Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), were collected on Porapak Q, and those from the male beetles were shown to contain two compounds, that wereExpand
Chemical Cues from Murgantia histrionica Eliciting Host Location and Recognition in the Egg Parasitoid Trissolcus brochymenae
Host location and recognition by the egg parasitoid Trissolcus brochymenae were analyzed in terms of response to kairomones from several stages of its host, Murgantia histrionica and results are discussed in relation to the level of the host selection sequence influenced by these cues. Expand
Isolation and identification of cotton synomones mediating searching behavior by parasitoidCampoletis sonorensis
This is the first report of spathulenol in cotton, and a new, naturally occurring bisabolene-related alcohol, (2-p-tolyl-6-methylhept-5-en-2-ol) which the authors name gossonorol. Expand
Stimuli influencing host microhabitat location in the parasitoid Campoletis sonorensis
The host microhabitat location behavior of females of the generalist parasitoid Campoletis sonorensis (Cameron) (Hymenoptera: Ichneumonidae) was studied in a wind tunnel and oviposition was the most important component of this experience. Expand
Estimation of Aerial Density of the Lesser Grain Borer (Coleoptera: Bostrichidae) in a Warehouse Using Dominica lure Traps
Aerial density of lesser grain borers, Rhyzopertha dominica (F.), flying in a warehouse was recorded hourly using a Johnson-Taylor suction trap. Lindgren funnel traps baited with Dominica lureExpand
Pyocyanin isolated from a marine microbial population: synergistic production between two distinct bacterial species and mode of action.
Experiments designed to probe the synergistic role of the microorganisms are presented and full characterization of the blue natural product, pyocyanin, is provided, showing the overall potential of the method to reveal the primary biological/cellular effects of a natural product. Expand
Structure and catalytic mechanism of LigI: insight into the amidohydrolase enzymes of cog3618 and lignin degradation.
LigI from Sphingomonas paucimobilis catalyzes the reversible hydrolysis of 2-pyrone-4,6-dicarboxylate (PDC) to 4-oxalomesaconate and 4-carboxy-2-hydroxymuconate in the degradation of lignin, the first enzyme from the amidohydrolase superfamily that does not require a divalent metal ion for catalytic activity.
