| 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... |

| 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... |

| 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... |

| 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... |

| 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... |
