“…The insect walking response to contact insecticides has been a subject of attention in stored‐product insects because it may further favour their survival,6, 21–24, 31 but this is the first report on the impact of phosphine (sublethal) exposure in insect locomotion. The present hypothesis was that exposure to phosphine would lead to a reduction in walking activity as a protective behaviour, thus decreasing metabolism and respiration rate and thereby minimising phosphine uptake.…”

“…Relatively little attention is paid to the sublethal behavioural response of insect pest species exposed to sublethal concentrations of insecticide, although insects have evolved a variety of responses to such compounds, reflecting the insecticide mode of action and the extent to which it affects behaviour 3, 4. Changes in insect behaviour under insecticide exposure may compromise control efficacy, a prospect that is particularly serious for insect populations already physiologically resistant to insecticides 5–7…”

Phosphine exposure decreased walking activity. Such reduced walking activity is likely to lower the respiration rate, thereby minimising phosphine uptake. As higher phosphine resistance was also associated with reduced walking activity, phosphine-resistant populations may resist phosphine fumigation even more efficiently on account of this behavioural trait, further aiding their physiological resistance, and should be a matter of concern.

Deltamethrin‐induced feeding plasticity in pyrethroid‐susceptible and ‐resistant strains of the maize weevil, Sitophilus zeamais

Phenotypic plasticity contributes to the adaptative evolution of populations exposed to new or altered environments. Feeding plasticity is a component of phenotypic plasticity not usually considered in insect strains adapted to insecticide‐altered environments, but which may either accentuate or mitigate insecticide resistance. This is a concern in the pyrethroid‐resistant strains of the maize weevil Sitophilus zeamais Motsch. (Col., Curculionidae), and the reason for this study. A pyrethroid‐susceptible and two pyrethroid‐resistant strains of maize weevil were subjected to free‐choice and no‐choice tests with maize grains sprayed with increasing doses of the pyrethroid, deltamethrin. The insects from the pyrethroid‐resistant strains exhibited higher feeding avoidance with increased deltamethrin doses than insects from the susceptible strain when subjected to free‐choice tests. The strains of maize weevil physiologically resistant to pyrethroids were also behaviourally resistant to deltamethrin – an additional management concern. The resistant strains avoid deltamethrin‐sprayed grains and are less nutritionally affected by this compound, with divergent responses from the susceptible strain with increased doses of deltamethrin. Furthermore, the higher relative growth rate and consequently higher efficiency of food conversion observed in the insecticide‐resistant strains were significant even without insecticide exposure, indicating that these traits are stimulus‐independent and may persist even without further insecticide selection, potentially limiting the options available for their management.

“…All insects were cultured under moderately crowded conditions to ensure proper development and equal size of the resultant adults. S. oryzae and R. dominica were reared on soft kernel wheat (Bell et al 1977;Padin et al 2002), O. surinamensis was reared on oat (Tunc¸bilek 1997), L. serricorne was reared on diet of wheat with 5% brewer's yeast (Soon et al 2003), used wheat and barley for C. ferrugineus (Cox et al 1997) and C. maculatus was reared on chickpeas (Ka´ita et al 2000).…”

The lethality impact of diatomaceous earth (Sayan 1 ), bran, sawdust and clay on six major stored-product insects under laboratory conditions was determined. The lethal effects were investigated in two different methods. In the first method, experimental surface was permeated with test material, and in the second method, the test compounds were mixed with rearing mediums separately. In the first technique, adults of Sitophilus oryzae, Rhyzopertha dominica, Oryzephilus surinamensis, Lasioderma serricorne, Cryptolestes ferrugineus and Callosobruchus maculatus were placed in a Petri dish, which was contaminated with a known amount of Sayan 1 , bran, sawdust or clay. Mortality rate was recorded at 24, 48 and 72 h after commence of each exposure. In the second method, the lethality of test compounds which were mixed with wheat was investigated against S. oryzae, R. dominica, O. surinamensis, L. serricorne and C. ferrugineus for 1, 7 and 14 days of exposure. In the first technique, the results indicated that bran and sawdust caused more mortality rate on S. oryzae compared to Sayan 1 . In the second method, the results demonstrated a higher mortality caused by bran and sawdust compared to Sayan 1 on S. oryzae. For L. serricorne, mortality rate caused by bran and sawdust was similar, whereas, in C. maculates case, mortality rate caused by bran was more than the other treatments. The protective effects of test compounds on life span of S. oryzae and R. dominica showed significant differences among the emerged adult of insects in different treatments. In the bran treatment, S. oryzae adult's emergence was the lowest, while, in the R. dominica case, a non-significant difference among resultant number of adult insects was detected.
