“…The addition of stones all over the floor of the arena was thought to give the beetles a more continuous touch stimulus, which enhanced the amount of time they moved around the whole area of the arena, thereby reducing the chances of the beetles to gather around the edges of the tray and increased the chances of detecting odour cues from the control and treated grain; a trend observed also by Campbell & Hagstrum, (2002). In the study presented here, in the open arena and pitfall arena a greater proportion of beetles was observed to walk continuously around the edge of the arena trays or the pitfall petri dishes, to hide behind the netting bags used to contain the grain samples or gather in the corners of the tray in the open arena assays.…”

“…In their study of the response of T. castaneum to an arena with a patchy environment, consisting of a smooth floor arena with patches of grain, Campbell & Hagstrum (2002) observed that a greater number of T. castaneum were found inactive in corners and edges of the arena than in the patches of grain, a behaviour which Kennedy (1986) The bioassay results indicate that only about 55-63% of the 40 beetles released in standard bioassays contributed to the assessment of candidate repellents, the rest never made a choice between treatments, whereas 88% of released beetles in the stimuli-enriched bioassay made a choice between the control and treatment grain sample. The addition of each component provided more physical cues, thereby increasing the efficiency of the assay.…”

“…A study by Campbell & Hagstrum (2002) of the behaviour of T. castaneum in a bioassay arena found that they moved across a bioassay arena more frequently if a network of walls was present throughout the arena. We tested the hypothesis that this is due, at least in part, to the strength of their response to thigmotactic cues; i.e that beetles prefer to maintain contact with substrates over as much of their bodies as possible, presumably to protect themselves from desiccation and from detection by predators (Romero et al, 2010).…”

New ‘stimuli-enriched’ laboratory bioassay used to identify improved botanical repellent treatment, Lem-ocimum, to control the stored-grain pest Tribolium castaneum

A laboratory study of Tribolium castaneum, a major pest of stored grain, was conducted to develop a more efficient and effective 'choice' bioassay for identification of new repellent botanical treatments. Standard bioassays to test the repellency of candidate plants include pitfall traps and open arena choice tests, environments lacking in some of the most important natural stimuli that guide the movement of food-searching beetles, e.g., 1) materials they can burrow through, which stimulate 'positive thigmotaxis', 2) a range of light and dark areas, which stimulate 'negative phototaxis' and 3) three-dimensional habitats, which stimulate 'positive geotaxis.' The lack of these stimuli can lead to two common problems; 'low efficiency' (high proportion of beetles remain in the area that surrounds treatments without making a 'choice'), and 'low efficacy' (high variability in proportions found in control and 2 treated samples). The new 'stimuli-enriched' bioassay, which included all three of the above stimuli, was significantly more efficient (Analysis of deviance; χ 2 =82.4, df=3, P<0.0001) and effective (χ 2 =30.6, df=3, P=0.0027) than three standard bioassays. The stimuli-enriched bioassay was used to compare the repellency of four candidate plants; Ocimum basilicum (Sweet Basil) and Cymbopogon nardus (Lemongrass) were significantly more repellent than Vernonia amygdalina or Nauclea diderrichii (Tukey Contrasts; P<0.01). A novel method of applying repellent material (a paste of repellent plant is applied between the layers of double bagged grain) was tested on the most promising repellent plants materials; a combination of C. nardus and O. basilicum ('Lem-ocimum') at 0.5% w/w of each was significantly more effective than O. basilicum on its own (Tukey Contrasts; P<0.05). These results show that the stimuli-enriched bioassay provides more consistent and accurate assessments than the standard bioassays of the repellency of candidate botanicals, and that Lem-ocimum treated double-bags are a promising new method of protecting sorghum from T. castaneum.

“…As demonstrated e.g. by Campbell and Hagstrum (2002) and Semeao et al (2013), adult storage pests have a high walking and flying capacity as well as behavioural traits for dispersal. Pest dispersal is furthermore facilitated by constructing various elevators, connecting elements that frequently include walking decks connecting silo bins at the top (roof ) silo/elevator area as depicted in Figure 1.…”

Aulicky R., Kolar V., Plachy J., Stejskal V. (2017): Field efficacy of brief exposure of adults of six storage pests to nitrogen-controlled atmospheres. Plant Protect. Sci., 53: 169-176.The efficacy of a brief exposure (1, 7, and 10 days) to a nitrogen-controlled atmosphere (N-CA) for major storage pests in a field validation study in the Czech Republic is reported. The main goal was to estimate how quickly the mobile adult stages of six species of storage beetles (oryzaephilus surinamensis, cryptolestes ferrugineus, tribolium confusum, tribolium castaneum, Sitophilus granarius, and Sitophilus oryzae) are killed after introduction of the infested commodity to prevent their further spread to the surrounding storage bins. The trials were conducted in a metal bin containing 25 t of seeds using the system of continual top-down nitrogen filling to replace the oxygen. The composition of N-CA in the silo was measured continually. The target N-CA concentration (i.e., ≤ 1% O 2 and 99% N 2 ) was reached at the bottom of the silo after 12 h of the purging phase of nitrogen silo filling. A one-day exposure to N-CA corresponds to top-down filling, which initially gives higher concentrations of N 2 in the upper than in the lower part of the silo: low efficacy was reached at the silo bottom (0-33.3%), while higher efficacy (16.7-100%) was reached at the top of the silo bin. The mortality variation at both locations was species dependent: the most sensitive was o. surinamensis, and the least sensitive were S. granarius and S. oryzae. Seven days of N-CA exposure led to 100% mortality of all tested species except for S. granarius (96.7% mortality at the bottom), while 10 days of N-CA exposure led to 100% mortality of all adults located at both the bottom and the top of the silo. This experiment showed that one day of exposure to N-CA caused significant mortality to reduce the spread of insects from the top of the silo but not from the silo bottom, and 10 days of exposure completely prevent the adult mobile pest stages of all tested species from spreading from the treated silo and causing cross-infestation in the storage facility.

-With the purpose of verifying the occurrence of insect pests in dog food commercialized in the Metropolitan Region of Recife, samples from 15 different pet stores were submitted to the extraction of insects in a Berlese-Tullgren apparatus. Tribolium castaneum (Herbst) (Tenebrionidae) (55.2%) was the most frequent specie followed by Oryzaephilus surinamensis (L.) (Cucujidae) (31.3%), Rhyzopertha dominica (Fabricius) (Bostrichidae) (8.9%) and Lasioderma serricorne (Fabricius) (Anobiidae) (4.7%), all from Coleoptera. Recife showed the highest rate of infestation (53.6%), followed by Olinda (34.4%) and Jaboatão dos Guararapes (12.0%). The infestation by coleopters in the region occurs with high frequency and may represent a threat mainly in commercialized products in bulk.KEY WORDS: Stored product insect, chow, infestation, products in bulk, storage RESUMO -Objetivando verifi car a ocorrência de insetos-praga em alimento industrializado para cães, comercializado na região metropolitana do Recife, amostras de 15 diferentes lojas agropecuárias foram submetidas à extração de insetos em funil de Berlese-Tullgren.
