Helicoverpa zea Boddie (Lepidoptera: Noctuidae), the corn earworm, is a key pest of sweet corn (Poales: Poaceae) in many parts of the United States. Integrated pest management (IPM) practices for H. zea in fresh and processing sweet corn use pheromone trap counts of male moths for management decisions. In this study, we examined whether sweet corn could be protected more effectively if insectic...

Boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), trapping and pheromone quantitative analysis of extended-life pheromone lures manufactured with 0, 10, 20, and 30 mg of eugenol was conducted in the Rio Grande Valley of Texas under spring and summer conditions. Boll weevils responded positively to eugenol on one of 12 trapping weeks when densities were high, but when ...

(Z)-5-dodecen-1-ol (Z5-12:OH), (Z)-5-dodecenyl acetate (Z5-12:Ac), and (Z)-5-tetradecenyl acetate (Z5-14:Ac) were found in the extracts of the female sex pheromone gland of the carpenterworm moth Holcocerus artemisiae Chou et Hua, a pest of Artemisia filifolia. The average amounts of Z5-12:OH, Z5-12:Ac, and Z5-14:Ac in a single sex pheromone gland of a calling moth were (7.14 +/- 0.73) ng, (54....

False codling moth (FCM) is regarded as the most significant indigenous pest. Over 70 host plants are attacked by larval, many of which horticultural crops with fruit, pods, and berries, such beans, grapes, citrus, capsicum, avocado, guava, pomegranate, ornamental plants. They eat macadamia nuts, cotton, tea, a variety other wild well. Female moths drawn to flower heads well parts plant, making...

Two detection methods for the little fire ant, Wasmannia auropunctata (Roger) (Hymenoptera: Formicidae), both employing the pheromone attractant 2,5-dimethyl-3-(2-methylbutyl)pyrazine (2-MeBu-diMePy), were compared with peanut butter based detection, in order to evaluate differences in species specificity and detection reliability. Trapping was conducted using a transect through a macadamia orc...

Pyramid traps coated with "industrial safety yellow" exterior latex gloss enamel paint and baited with Euschistus spp. aggregation pheromone, methyl (2E,4Z)-decadienoate captured more stink bugs than all other baited and unbaited trap types in both apple and peach orchards in 2002 and 2003. Commercial sources of dispensers of methyl (2E,4Z)-decadienoate deployed in association with pyramid trap...

Sterile mass-reared Mexican fruit flies, Anastrepha ludens (Loew), were trapped in a citrus orchard by using multilure traps and cylindrical sticky traps baited with Advanced Pheromone Technologies Anastrepha fruit fly (AFF) lures or Suterra BioLure two-component (ammonium acetate and putrescine) MFF lures (BioLures). The cylinder trap/AFF lure combination was the best trap over the first 6 wk,...

We collected a native North American species, Phyllocnistis insignis (Frey & Boll) (Lepidoptera: Gracillariidae), in traps baited with a 3:1 blend of (Z,Z,E)-7,11,13-hexadecatrienal (triene) and (Z,Z)-7,11-hexadecadienal (diene), 2 components of the sex pheromone of the invasive citrus leafminer, P. citrella Stainton. No moths were caught in unbaited traps during 6 months of monitoring. We eval...

Abstract Halyomorpha halys (Stål, 1855), the brown marmorated stink bug (BMSB), is an invasive species that has become a key agricultural pest in its invaded range. Commercial traps available for BMSB monitoring rely on male produced aggregation pheromones as lure, with two possible shortcomings: trap spillover and low detection precision. In this study, we assessed if vibrational signals can i...
