Attraction of Neomegalotomus parvus (Westwood)(Heteroptera: alydidae) to cow urine and ammonia 63
Silva,Jovenil José da; Arruda-Gatti,Iara Cintra de; Mikami,Adriana Yatie; Pissinati,Aline; Panizzi,Antônio Ricardo; Ventura,Mauricio Ursi.
The alydid bug parvus (Westwood) is not easily detected in the field and the discovery of attractants may be a suitable way to monitor this species. The attraction of N. parvus to traps (transparent, transparent green and yellow) baited with cow urine and ammonia was studied in two field trials. Traps were placed near a terrace with pigeon pea plants (Cajanus cajan L.). Tap water, NaCl 10% aqueous solution (w/v), cow urine, and ammonia (NH4OH 1% aqueous solution) were tested as attractants in yellow, transparent and transparent green traps. Green traps baited with cow urine caught more bugs than yellow and transparent traps (3.2 and 7.2 times more, respectively), and more bugs than traps of the same color with just water (no captures) or NH4OH solution...

Calibration and evaluation of field cage for oviposition study with Aedes (Stegomyia) aegypti female (L.) (Diptera: Culicidae) 82
Roque,Rosemary A.; Eiras,Álvaro E..
Differences among results gathered from insect behavior studies conducted in laboratory and field situations are due to ambient variables that differ greatly between both environments. In laboratory studies the environmental conditions can be controlled whereas in field temperature, humidity and air velocity vary uncontrollably. The objective of this study was to calibrate and evaluate an experimental area (field cage) (14 x 7 x 3.5 m) subdivided into eight test cages (2.5 x 2.5 x 2 m) for use in behavioral oviposition tests of Aedes aegypti (L.) mosquitoes for developing a new methodology to assess attractants and oviposition traps. Test cage calibration involved: (1) minimal experiment duration tests; (2) optimal female release number per traps test and...

Capture of hypothenemus hampei ferrari (coleoptera, scolytidae) in response to trap characteristics 63
Silva,Flávia Cloclet da; Ventura,Maurício Ursi; Morales,Lauro.
Traps lured with semiochemical have been proposed to manage the coffee berry borer, coffee planting is however made under several environmental conditions that may affect the efficacy of traps. Several trap designs and variations were proposed and, therefore, a series of field experiments was carried out to capture coffee berry bores in traps disposed in a low density coffee plantations in the Northern part of the State of Paraná, Brazil. Traps were composed of plastic bottles (2 L) with a window (13 × 18 cm). Ethanol (E), Methanol (M) and coffee oil alone did not improve the capture when transparent traps with a 2 mm hole in the vial dispenser were used; traps lured with E : M mixtures (1:1, 1:2, 1:3) caught similar and higher number of insects than the...

Field tests of predaceous pentatomid pheromones and semiochemistry of Podisus and Supputius species (Heteroptera: Pentatomidae: Asopinae) 44
Aldrich,Jeffrey R.; Zanuncio,José C.; Vilela,Evaldo F.; Torres,Jorge B.; Cave,Ronald D..
Traps baited with synthetic pheromones for either Podisus nigrispinus (Dallas) or Supputius cincticeps (Stäl) were field tested at the Universidade Federal de Viçosa, Minas Gerais, Brazil, beginning September 7, 1995. No P. nigrispinus were caught but, in September and October, several adult males and females of P. distinctus (Stäl) were caught along with a few adults of S. cincticeps and two females of a tachinid fly parasitoid, Cylindromyia atra Roeder. Chemical analysis of the pheromone gland extract of P. distinctus males indicated that this species produces a pheromone containing the major compounds of P. nigrispinus and S. cincticeps. Therefore, on November 6 a set of traps was baited with the pheromones of both P. nigrispinus and S. cincticeps, and...

Identification of a novel plant-derived attractant for Acromyrmex lobicornis leaf-cutting ants 42
ALMA,ANDREA M.; FERNANDEZ,PATRICIA C.; PERRI,DAIANA; BUTELER,MICAELA.
Abstract: Leaf-cutting ants are considered major pests of agriculture and forestry in the Neotropics. Attractive toxic baits are the prevailing method for managing them. Thus, there is great interest in identifying attractants to incorporate into these baits. Moreover, leaf-cutting ants can avoid toxic baits by associating the attractant with the toxin. We evaluated attractiveness of heptyl butyrate, a volatile compound found in fresh apples and plums. We conducted field experiments with ten colonies ofAcromyrmex lobicornis. First, we evaluated the behaviour of ants exposed to heptyl butyrate at 1% by surrounding resources. Then, we compared the attractiveness of heptyl butyrate and orange pulp, the most commonly used attractant. Finally, we evaluated...

Responses of Coffee berry borer, Hypothenemus hampei (Ferrari)(Coleoptera: Scolytidae), to vertical distribution of methanol: ethanol traps 82
Uemura-Lima,Daliana H; Ventura,Maurício U; Mikami,Adriana Y; Silva,Flávia C Da; Morales,Lauro.
Captures of the coffee berry borer (CBB) Hypothenemus hampei (Ferrari) were assessed in traps in the field. IAPAR designed traps [plastic bottles (2 L) lured with methanol:ethanol (1:1) in a vessel] were placed either at 0.5, 1.0 and 1.5m high from the ground or simultaneously tested in the 2004 fructification season. Traps placed at the three heights trapped 5.5 times more CBB than the others, mostly at the traps placed at 0.5 m (75%). Treatments using the IAPAR designed trap placed at 1.2 m high; IAPAR trap with a white plastic plate above (IAPAR modified I) at 1.2 m high; IAPAR at 0.5 m high and two additional vessels at 1.0 and 1.5m high (IAPAR modified II) and T-163 trap [three red plastic cups (300 ml) and a red plastic plate as a cover] lured with...

Trap attributes influencing capture of Diabrotica speciosa (Coleoptera: Chrysomelidae) on common bean fields 63
Ventura,Maurício Ursi; Resta,Claudio Cezar Mariano; Nunes,Daiane Heloísa; Fujimoto,Fabio.
Refinements in trap characteristics may improve ability to monitor and mass-trap beetles. Field assays were conducted in common bean fields to assess responses of Diabrotica speciosa (Germar) to some trap characteristics. Golden yellow plastic cups (750 mL) traps caught more D. speciosa females and males than did clear traps. Carrot slices in Petri dishes baited with Lagenaria vulagaris L. powder (cucurbitacin source - 0.28%) caught more beetles than did dishes with carrot alone. Dispensers for the floral volatile attractant 1,4-dimethoxybenze were also compared. Rubber septa dispenser attracted more beetles than did control (dental wicks saturated with acetone). Captures on dental wick, starch matrix and feminine pad dispensers were intermediate and did...
