Vertical distribution patterns of Mexican rice borer, Eoreuma loftini (Dyar), larvae and tunnels in Lower Rio Grande Valley sugarcane, Saccharum spp., were examined by stalk dissections in commercial sugarcane from late May until early September (199

Nighttime amounts were determined for five volatile chemicals identified in extracts ofGaura drummondii flowers. The major component (2-methylbutanal oxime, isomers1 and2) occurred at the highest level during the earliest sampling period (20:00–23:

Pupal development times and thermal unit requirements, daily adult eclosion patterns, and the durations of phases of emergence of the Mexican rice borer, Eoreuma loftini (Dyar), adult sexes were observed under reversed photoperiodic and thermoperiodi

When Mexican rice borers, Eoreuma loftini (Dyar), were provided a surplus of mates, an average of 91.0% and 88.3% of laboratory-reared Mexican rice borer males and females, respectively, mated on the night following eclosion. Males mated as many as f

Sperm transfer and spermatophore disintegration in females and duplex refilling in males of the Mexican rice borer, Eoreuma loftini (Dyar), were examined by freezing moths at time intervals after mating. Eupyrene sperm location and spermatophore cond

Timing and magnitude of corn earworm, Helicoverpa zea (Boddie), emergence was measured in a corn, Zea mays (L.), field near College Station, TX. Approximately 15,500 H. zea per hectare were produced, with 85% of the moths emerging in a 10-d interval.

The effect of the pheromone of Mexican rice borer, Eoreuma loftini (Dyar), on mating of laboratory-reared females to feral males was tested on mating tables in sugarcane fields. Reductions of 94.3 and 90.5% in mating was obtained using pheromone form

Different enantiomeric ratios and elution rates of the inhibitor pheromones verbenone and racemic endo-brevicomin were evaluated for their effects on the numerical response of the southern pine beetle, Dendroctonusfrontalis Zimm., to attractant-baite

The Universal Moth Trap (Unitrap) caught more male Mexican rice borers, Eoreuma loftini (Dyar), than 13 other trap types. Traps placed 5 m within sugarcane fields captured significantly more male Mexican rice borers than traps at the edge of the fiel

Formulations of Mexican rice borer (MRB) pheromone components were more effective in capturing males in fields of sugarcane when dispensed from rubber septa than when evaporated from four other substrates. Concentrations of 0.63-10.0 mg of total pher
