“…The results presented in this study conÞrm previous general conclusions that: 1) the species of the genus Sitophilus are more sensitive to DEs than those of Tribolium, especially after short-time exposures (Korunić 1997, Fields and Korunić 2000 and also to natural zeolites (Kljajić et al 2010); 2) the mortality of stored-product insects increases signiÞcantly with increased duration of their exposure to wheat treated with DEs (Fields et al 2003; 3) the total mortality of insects exposed to wheat treated with different inert dusts, including natural zeolites, after recovery, also increases (Arthur 2001;Collins andCook 2006a, 2006b;Kljajić et al 2010); 4) the dose rates used are relatively high, or at least similar to those of the registered DEs; 5) the efÞcacy of DE based inert dusts depends primarily on the silicium dioxide content and particle size distribution, so that the highest efÞcacy is achieved with DE dusts of uniform particle size distribution with a mean particle size of about or below 10 m, higher percentage of particles with diameters below 12 m, and high amorphous SiO 2 content (Korunić 1997(Korunić , 1998; and 6) DE based inert dusts, with amorphous silica structure, are more effective than natural zeolite dusts as crystalline hydrated aluminosilicates (Kljajić et al 2010), where zeolites have some speciÞc disadvantages because of the presence of more crystaline ingredients or smaller particles.…”

“…Haryadi et al (1994) have shown that natural zeolite can be effective in controlling maize weevil Sitophilus zeamais (Motsch), but the rates applied in this study were very high (Ն50 g/kg of maize). Kljajić et al (2010) have also found high effectiveness of natural zeolite originating from Serbia, applied however at much lower rates (0.75 g/kg) and low relative humidity (r.h.) (40 Ð 45% r.h.), against three stored-product beetle pests in treated wheat.…”

Insecticidal potential of natural zeolites and diatomaceous earths originating from Serbia against Sitophilus oryzae (L.) and Tribolium castaneum (Herbst) was evaluated. Two natural zeolite formulations (NZ and NZ Modified) were applied to wheat at rates of 0.50, 0.75, and 1.0 g/kg, while two diatomaceous earth (DE) formulations (DE S-1 and DE S-2) were applied at rates of 0.25, 0.50, 0.75, and 1.0 g/kg. A bioassay was conducted under laboratory conditions: temperature of 24 +/- 1 degrees C, relative humidity in the range 50-55%, in tests with natural zeolites, and 60-65%, in tests with DEs, and in all combinations for progeny production. Mortality was assessed after 7, 14, and 21 d of insect contact with treated wheat, and the total mortality after an additional 7-d recovery on untreated broken wheat. Progeny production was also assessed after 8 wk for S. oryzae and 12 wk for T. castaneum. The highest mortality for S. oryzae and T. castaneum was found after the longest exposure period and 7 d of recovery, on wheat treated with NZ at the highest rate and DEs at rates of 0.50 -1.0 g/kg. Progeny reduction higher than 90% was achieved after 14 and 21 d of contact of both beetle pests with wheat treated with DE S-1 at 0.50-1.0 g/kg and DE S-2 at 0.75-1.0 g/kg, while the same level of reduction was achieved only for T. castaneum after its contact with the highest rate of NZ formulation. NZ Modified, applied even at the highest rate, revealed much lower insecticidal potential.

“…Inert dusts can be mixed with different stored agricultural grains to control stored grain pests and different crawling pests in storages and in different industrial objects for food production. Inert dusts do not deteriorate or break down, and therefore, provide long-term control of insect pests and are almost completely harmless to humans and mammals (Maceljski and Korunic (1972), Fields and Muir (1996), Subramanyam and Roesli (2000), Arthur and Puterka (2002), Kljajić et al (2010) gave detailed guidelines on the key aspects for the use of inert dusts as a possible alternative to synthetic pesticides in stored products, and proposed inert dusts to be included into IPM program.…”

Laboratory tests on insecticidal effectiveness of disodium octaborate tetrahydrate, diatomaceous earth and amorphous silica gel against Sitophilus oryzae (L.) and their effect on wheat bulk densityLaboratorijska testiranja insekticidne učinkovitosti dinatrijevog oktaborat tetrahidrata, dijatomejske zemlje i amorfnoga silika gela na Sitophilus oryzae (L.) te njihov utjecaj na hektolitarsku masu pšenice Korunić, Z., Rozman, V., Liška, A., Lucić, P. Original scientific paper Izvorni znanstveni članak SUMMARY We examined insecticide effectiveness of three different inert dusts: disodium octaborate tetrahydrate (DOT) and diatomaceous earth (DE) Celatom ® Mn 51 applied as powder and suspension, and silica gel Sipernat® 50 S applied as powder against Sitophilus oryzae (L.) and their reduction of grain bulk density. Sipernat ® 50 S was the most effective dust with a very fast initial effectiveness. DE and DOT generated similar effectiveness against S. oryzae. DOT generated low initial effectiveness but after prolonged exposure time of 8 and especially after 21 days, the mortality was very high (100%), similar to the effectiveness of DE. The similar order of dusts was obtained in the reduction of wheat bulk density. Applied at dose of 200 and 500 ppm, the lowest bulk density difference in regard to bulk density of untreated wheat had DOT (-1.1 and -1.9 kg hl -1 , respectively), followed by Celatom ® Mn 51 (-3.5 and -4.3 kg hl -1 , respectively) and Sipernat ® 50 S (-5.2 and -5.5 kg hl -1 , respectively). Due to the effect on wheat bulk density DOT belongs to the group with the least negative effect on bulk density and therefore, it is a promising dust to control stored grain insect pests.

“…For instance, it is used to control warehouse pests (Golob 1997;Subramanyam and Roesli 2000;Kljajić et al 2010) to protect plants against insects from different orders (Markó et al 2008;Mikami et al 2010;Muncha-Pelzer et al 2010) and also against various plant diseases (Glenn et al 1999;Glenn and Puterka 2005). It has a physical or deterrent mode of action (Subramanyam and Roesli 2000;Markó et al 2008) which allows its use in organic and IPM programmes according to European IPM directive 2009/128.…”

Sublethal effects of kaolin and the biopesticides Prestop-Mix and BotaniGard on metabolic rate, water loss and longevity in bumble bees (Bombus terrestris)

Kaolin is an inert material with a broad range of applications, e.g. as an insecticide and as a filling substance in the formulation of biopesticides. Hence, bees that dispense biopesticides to the field in the context of entomovectoring are exposed to elevated risks because of sideeffects of those products. Here, we investigated with use of bumble bee workers of Bombus terrestris L. the lethal and sublethal effects of (i) pure kaolin, (ii) the biofungicide Prestop-Mix containing the parasitic fungus Gliocladium catenulatum and kaolin and (iii) the bioinsecticide BotaniGard containing the entomopathogenic fungus Beauveria bassiana and compared with wheat flour powder that we considered safe for bumble bees. As the most important result, treatment with kaolin increased the cuticular water loss and reduced the survival of treated bumble bees, while Prestop-Mix had no negative effect on longevity. BotaniGard caused mortality in the bumble bees because of the entomopathogenic spores it contained. In conclusion, our data indicated that substances used as 'inert materials' and in biocontrol agents which are used in IPM and organic farming systems may bring higher risks to bumble bees used in entomovector technology.
