“…The consequence is that the elevator manager may frequently add phosphine tablets when moving the grain from bin to bin without sampling first to see if treatment is necessary. Another option is to use a vacuum probe sampler in combination with an inclined sieve to sample insects as deep as 12 m into the grain mass (Flinn et al 2007). Once all of the bins at an elevator have been sampled, the manager can fumigate only those bins that have infestations above a certain threshold.…”

“…The sampling of wheat at 10 rural elevators and one terminal elevator in Kansas, USA, and a similar group in Oklahoma, USA, every six weeks, provided a good example of using economic thresholds and sampling-based fumigation (Flinn et al 2007). A vacuum-probe sampler was used to take ten 3-kg grain samples in the top 12 m of each wheat-containing elevator bin.…”

Stored-product entomologists have a variety of new monitoring, decision-making, biological, chemical, and physical pest management tools available to them. Two types of stored-product insect populations are of interest: insects of immediate economic importance infesting commodities, and insects that live in food residues in equipment and facilities. The sampling and control methods change as grain and grain products move from field to consumer. There are also some changes in the major insect pest species to take into consideration. In this review, we list the primary insect pests at each point of the marketing system, and indicate which sampling methods and control strategies are most appropriate. Economic thresholds for insect infestation levels developed for raw commodity storage, processing plants, and retail business allow sampling-based pest management to be done before insect infestations cause economic injury. Taking enough samples to have a representative sample (20-30 samples) will generally provide enough information to classify a population as above or below an economic threshold.

“…Decision support software (STORED GRAIN ADVISOR PRO, http://ars.usda.gov/ npa/ gmprc/bru/ sga, Flinn et al, 2007b) was developed for wheat stored at elevators. This program uses information on insect density from vacuum probe grain samples to make decisions for each bin at an elevator.…”

“…With vacuum probe sampling of all bins and the decision support software discussed above, a private consulting company has provided scouting services to more than 70 elevators in Kansas, Oklahoma and Nebraska during the past 5 years (Flinn et al, 2007b). The sampling programme has improved insect pest management by ensuring that fumigation is done at the time when it will be most effective.…”

Areawide Pest Management: Theory and Implementation

View full text Add to dashboard Cite

This chapter describes an areawide pest management programme for insect pests of stored grains (focusing on wheat), considering the operating practices of elevators; the economic losses attributed to insects; the natural enemies of stored-grain insects; and the current insect pest management practices at elevators. Calendar-based fumigation of all of the grain at an elevator is not cost-effective because usually only a percentage of the bins require fumigation at any one time. Delaying the fumigation, when possible, until the autumn has several benefits: (i) the grain can be cooled with aeration after an autumn fumigation, which decreases subsequent population growth; (ii) insect immigration rates into grain bins in the autumn and winter are lower than during the summer; and (iii) the necessity for a second fumigation is greatly reduced because of (i) and (ii). Areawide, sampling-based pest management at each elevator or across the grain-marketing system using decision-support software can minimize the cost and maximize the effectiveness of insect pest management. In addition, it should reduce the risk of economic losses due to insects, the amount of wheat that is fumigated and the frequency of fumigation.

SummaryExperiment was conducted to determine the persistence and insecticidal efficacy of a new enhanced diatomaceous earth, Inert-PMS, in wheat against four stored grain insect pests [Cryptolestes ferrugineus (Stephens), Liposcelis paeta Pearman, Rhyzopertha dominica (F.) and Tribolium castaneum (Herbst)] under the laboratory conditions at 50, 75 and 100 mg/kg, for intervals of 24 h, 4 and 7 d at 28ºC and 65% RH. For persistence, Inert-PMS was applied to stored grain for 0, 30, 60, 90 and 120 d. The results demonstrated that adult mortality was directly proportional to the dose and exposure interval. While the efficacy remained constant up to 60 d, it fell after 90 and 120 d of storage. L. paeta and C. ferrugineus were the most susceptible to Inert-PMS (100% mortality) followed by R. dominica (81%) and T. castaneum (72%) at 75 mg/kg after 4 d. Inert-PMS also suppressed the reproduction at lower dose rates. Inert-PMS is an eco-friendly formulation that not only interferes with the growth and development of stored grain insects but is also cheap and free from ill effects. Keywords: Cryptolestes ferrugineus, Liposcelis paeta, Rhyzopertha dominica, Tribolium castaneum, Inert-PMS, new enhanced diatomaceous earth ÖzetBu çalışma, yeni geliştirilmiş diatomlu bir toprak olan Inert-PMS'in dört farklı depolanmış buğday zararlısına [Cryptolestes ferrugineus (Stephens), Liposcelis paeta Pearman, Rhyzopertha dominica (F.) ve Tribolium castaneum (Herbst)] karşı kalıcılığı ve insektisit etkilerini belirlemek amacıyla, 24 saat, 4 ve 7 gün aralıklarla 50, 75 ve 100 mg/kg dozları uygulanarak 28ºC sıcaklık ve % 65 orantılı neme sahip laboratuvar koşullarında gerçekleştirilmiştir. Kalıcılığını belirlemek için, inert PMS'in etkisi 0, 30, 60, 90 ve 120 gün süresince depolanan buğdaylarda değerlendirilmiştir. Sonuçlar, ergin ölümünün doz ve maruz kalma aralığı ile doğru orantılı olduğunu göstermiştir. Etki, 60 günlük depolamada sabit devam ederken, 90 ve 120 günlük depolamada ise düşmüştür. 75 mg/kg uygulama dozunda 4 gün sonununda, L. paeta ve C. ferrugineus Inert-PMS'ye en hassas türler olmuş (%100 ölüm), bunu R. dominica (%81) ve T. castaneum (%72) izlemiştir Inert-PMS, ayrıca düşük dozlarda da üremeyi baskılamıştır. Çevre dostu bir formülasyon olan Inert-PMS, depolanmış buğday zararlılarında sadece büyüme ve gelişmeye müdahale etmekle kalmayıp, aynı zamanda ucuzdur ve olumsuz etkileri de yoktur. Persistence and insecticidal efficacy of a diatomaceous earth formulation, Inert-PMS, in stored wheat grain against Cryptolestes ferrugineus (Stephens), Liposcelis paeta Pearman, Rhyzopertha dominica (F.) and Tribolium castaneum (Herbst)
