The species responding to baits represent a relatively small sample of the meliponine guild, and may be biased to include foraging generalists, rather than specialists. Both of these species also responded to baits throughout the day. To keep seed availability roughly constant throughout our experiments, baits were replenished when necessary. The highest values for mean species richness, percentage of baits attacked and intensities of attack, all occurred during the transitional season. Untreated control: natural baits without the application of any substance, and placed on unprotected plants. The frequency of captured a nd non-captured larvae or baits in each bioassay were compared as in the ant experiments. The use of relatively small baits ensured that competition would have occurred even at low beetle densities. Further examination of species distributions on baits in a plot during a single observation, however, provides evidence of mild interspecific interaction. No direct relationships were noted between rainfall recorded at the sites and species richness, frequency and intensity of attack on baits. Examination of baits may disrupt termite foraging for some period because the anchoring wire and planter bag must be removed for inspection. The five baits inspected at any given census were randomly selected from those baits that had not been previously examined. Simple linear regressions were also used to test for relationships between rainfall and mean species richness, percentage of baits attacked, intensities of attack. The number of manholes baited varies from year to year. In the second trial, small aircraft were used for distribution of praziquantel baits (20/km2) according to the protocol of concurrent rabies immunization campaigns. Inset shows the pattern of baited holes (filled circles) out of 36 holes (open circles) used during training. Both traps in the fourth chambers were baited with hexane-treated septa. All previous studies of blowfly aggregation have used traps baited with carrion. Sampling was conducted using ground and baited arboreal pitfall traps, and yielded a total of 95 ant species. The reliability of baiting to determine colony abundance and distribution is assessed. Resampling of selected locations tested the repeatability of responses of bees to baits. By locating and following foragers rather than using baits, we were able to track the normal home ranges of the ants. Secondly, the testing of baits should not be linked to estimating the number of termites in foraging populations. From the perspective of the termites, inspection and replacement of baits creates another, possibly important, deviation from foraging on natural foods. There was no significant difference in captures between traps baited with butyl hexanoate alone and traps baited with both butyl hexanoate and ammonium carbonate. Targets were baited with 300 g of lamb liver and 10 g of crushed sodium sulphide. The success of an insecticide in baits will depend on its palatability to termites and on its being transferred between termites in an active form. The possible use of hydramethylnon impregnated baits for the control of subterranean termites is discussed. The traps were baited with octenol and compared in paired blocks with 8 replicates. The presence of ant species and their relative abundances in rice fields during the dry fallow and rice crop seasons were determined using baits. One possible method of increasing the attractiveness of baits is pheromone enhancement. Hunting or baiting scenes occur on the north or east walls, the side of the dead. The situation is quite different if insecticide treated baits (traps, targets or livestock) are continuously maintained in the control area. Not every area within each borough was baited every year. In the present study, however, data were collected in restricted areas around individual dens where baits were distributed. Baits and footmarks were checked every day until the fourth day, and new baits were added if the original baits disappeared. The mean numbers of faeces collected every month were 86n0 (57-155) and 103n7 (71-151) in the baited and the non-baited sections, respectively. Carnivores were captured using locally made spring-traps, which were baited with fish or meat. Two control faecal baits were randomly positioned at two opposing quarters of the arena. Schelling and colleagues [16] temporarily observed a distinct reduction of the prevalence when baits containing praziquantel were distributed at intervals of 8-14 weeks. Chemotherapy with praziquantel baits may be a more acceptable method. Both studies recorded significant decreases in the percentage of coproantigen-positive specimens from baited areas compared to control areas. In this study, foxes were baited with a highly efficient drug against cestodes (praziquantel) in 5 blocks of 1 km2. Consider, however, the possibility that certain animals might be conceptualized in terms of their suitability for being teased or baited. Workings within the baits were lined with loose soil and black carton. A variety of baits was used for trapping, but chicken entrails proved to be the most effective. Ants were baited with milled rice that was sieved into five particle sizes: < 0.2, 0.2-0.5, 0.5-0.8, 0.8-1.5 and 1.5-2.5 mm. Each morning, seed baits were put several metres further into the forest to avoid re-sampling the same ant colonies. Seed baits were set out after dawn (07h00) and at midday (c. 12h00). First, steep hills did not prevent bees from locating baits on the opposite side from where they were released. Under such conditions the baits o could have been more attractive for hungry soil animals there. Feeding = number of experiments in which workers were observed to feed on the rice baits. The sample sizes, n, are the number of baits at which at least one individual in the species was observed. More species might be attracted to baits in the canopy. No escalated aggression (grappling or biting) was ever observed at carrion or honey baits. Slight modifications were made in the baits as experience was gained in baiting bees. Neither honey baits nor carrion baits attracted bees at 16 stations at 50-m intervals along a 750-m transect in recently abandoned pasture. To interpret the distributions of stingless bee colonies in our studies we assume that bees attracted to contiguous baits are from the same colony. The species used for the baits varied with the season and all fruit species were subjected to this treatment whenever available. Sampling is typically conducted by placing rotting banana baits at or near the ground and returning periodically to collect flies. On unprotected plants the disappearance of baits treated with shield extract was significantly lower than solvent controls and untreated controls. Within-habitat heterogeneity in baiting samples of male euglossine bees: possible causes and implications. In these experiments, use of odour baits with the biconical trap increased its efficiency by 2.4 times for males and 5.9 times for females. Beneath the holeboard was a second board on which food pellets were scattered randomly to avoid odour information from baited holes. The different termite species attacked the baits in characteristic ways. In contrast to rearing, baited t raps appear to be highly efficient in monitoring l ure-responding species of fruit fl ies in tropical f orests. Unfortunately, no complete phenological records are available for the different localities t hat could be linked t o t he baiting data. Close to the fruit plots, sample plots were established, and baited with known amounts of fruit. Placement of baits occurred between 08h00 and 10h00. Pitfall traps were baited at 18 h and retrieved 24 h later at all sites investigated. In the cases where many individuals were recruited to the baits, we collected individuals at nests. Spheres were either unbaited, baited with butyl hexanoate (synthetic host fruit odour) or baited with both butyl hexanoate and ammonium carbonate (synthetic food odour). The second trap was baited with a nylon stocking worn for four to seven days. In general, the termites sealed off the bases from the baits, and the baits were then ignored. Probabilities for mobile baits are likely to be higher but currently we have no reliable data to provide estimates for these. Particular attention needs to be paid to problems of scale, coverage with baits of the infected area, and of likely rates of re-invasion. The dynamics of the control process are similar in each case and the results of campaigns using different baits can be analysed using similar methods. Small baits were inspected by lifting the opaque plastic cover, lifting the baits, and examining the paper. They were arranged so that control and baited blocks alternated geographically. The study area (200 km#) was divided into baited and non-baited sections. Anthelmintic baits were distributed to each resident fox family in the baited section. I walk round the rocky coast, clambering over many walls, and am baited by three small boys. Two targets were baited with fresh liver and two with liver that had been aged for 14 days, as described previously, prior to deployment. Beetles were removed from the three traps and baits replaced each week for the three-week period following pat placement. Another advantage of the large baits is that they were placed only once, at the beginning of the study. There are many termite pest species in many different countries against which baits are deployed. The larvae were positioned in the centre of the arena, equally distanced from all baits. Nevertheless, the results suggest that alarm pheromone compounds have significant potential to improve the efficacy of baits for the control of grass-cutting ants. Moreover, the probability relates only to stationary baits. The chimpanzees cannot see which container is being baited as a result of the placement of the screen. In this experiment, there was also no significant difference between a trap baited with carbon dioxide and one baited with foot odour. Captured mature females tended to leave blocks with unbaited traps in numerically larger proportions than blocks with baited traps (fig. 4a). Two infective faecal baits were then positioned in the two remaining areas. The traps were cleaned, baited again and put out for the next night on the same place. However, our data only represent the early stages of the developing impact of baiting the fox population. Due to time constraints, baits were not employed, and termite species were not identified.
