Circadian changes in the susceptibility of adult individuals of three cricket species: field cricket (Gryllus campestris), house cricket (Acheta domesticus), and tropical house cricket (Gryllodes sigillatus) to insecticides belonging to the group of synthetic pyrethroids (Bulldock 025 EC) and oxadiazine (Steward 30 WG) were tested in 2007 and 2008. The assessment included the intoxication of subsequent groups of animals with insecticides at four crucial times of the diurnal cycle – at sunrise, at noon, at sunset, and at midnight. Due to the strongly developed territorial behaviour of Gryllidae, which may strongly affect the results of the analysis, tests were performed both on animals kept separately and on groups of 10 individuals. The application of Steward 30 WG and Bulldock 025 EC caused a significant decrease in the animals’ survival rate to the level of 41% (intoxication at midnight) and 38% (intoxication at sunrise) in G. campestris; 50% (intoxication at sunset) and 61% (intoxication at midnight) in A. domesticus; and 45% (intoxication at midnight) and 50% (intoxication at sunrise) in G. sigillatus, respectively. In the case of G. campestris (the control group) and G. sigillatus (group treated with Bulldock 025 EC) the size of tested groups had a significant influence on their survival rate.

Circadian and seasonal changes in the susceptibility of honeybee (Apis mellifera) workers to intoxication by organophosphate, benzoylphenyl urea, carbamate, and oxadiazine insecticides have been studied from 2008 to 2009. Animals were collected in two apiaries located in the surroundings of Mielec and Tarnobrzeg in the Sub-Carpathian Province. The experiments consisted of intoxication by select xenobiotics of the subsequent groups of animals in two-hour intervals for a period of 24 hours and the analysis of their survivability. Experiments were carried out in spring and summer. The results suggest that the susceptibility of bees to different groups of insecticides varies significantly, both in the circadian and seasonal rhythms.

In 2007 and 2008 studies aimed to determine the effect of preparation belonging to carbamate compounds (Pirimor 500 WG), organophosphorus compounds (Diazol 500 EW), and quinazolin compounds (Magus 200 SC), on the oxygen consumption rate by adult beetles Anoplotrupes stercorosus were performed. Experiments were carried out under diverse ambient temperatures (14, 19, 24 i 29°C) using two ways of intoxication – contact intoxication or intoxication by ingestion of the biocide. In control insects the ambient temperature affected the oxygen demand only to a small extent. Usually, insecticide preparations which were used, markedly potentiated the oxygen consumption. In those experimental groups significant increases of oxygen consumption as the effect of ambient temperature elevation were noted. The mode of the intoxication influenced oxygen consumption only very slightly. The highest values of oxygen consumption were noted in animals treated by contact intoxication.

Field tests verified and evaluated a pesticide’s active ingredient transfer to honeybee hives from rapeseed crops protected according to current programs. Samples of rapeseed flowers, leaves, and soil were collected, as well as of worker honeybees, the brood, and honey from hives located in the crops. They were evaluated for the presence of four insecticides and five fungicides. In flower samples and leaf samples flutriafol at plantation 1 and azoxystrobin at plantation 2 were found at the highest levels. In honeybees and in the brood, five AIs were detected at plantation 1, of which the highest levels were observed for flutriafol (25.5 μg/kg of honeybee) and picoxystrobin (7.3 μg/kg of brood). At plantation 2, residues of three and two AIs were detected in honeybees and in the brood, respectively, of which chlorpyrifos was at the highest level (19.5 μg/kg of honeybee, and 2.8 μg/kg of brood). For both plantations, residues of three AIs were found in honey. The AI levels in honey did not exceed 3.8% of acceptable maximum residue level at plantation 1, and 2.8% at plantation 2. The percentage of acceptable daily intake did not exceed 0.01%.

We examined the susceptibility of the worker honeybee Apis mellifera L. to pyrethroids. Bees were intoxicated by selected synthetic pyrethroids (active substances: beta-cyfl uthrin, deltamethrin, alphacypermethrin, lambda-cyhalothrin, esfenvalerate, and bifenthrin) and 72 hours after intoxication the number of surviving insects was determined. It was observed that the susceptibility of the honeybee to pyrethroids (expressed herein as the survival rate) was changing in diurnal rhythm, ranging from 100% (for a majority of substances in both seasons) to 11.1±0.37% (deltamethrin) and 11.1±0.73% (esfenvalerate) in spring, and 11.1±0.73% (esfenvalerate) and 4.6±0.17% (bifenthrin) in summer. The lowest susceptibility of bees to pyrethroids occurred during the night, when the honeybees were characterized by reduced motility and did not fl y out for foraging, whereas the highest susceptibility was observed during the day, a natural time for seeking food. Along with diurnal changes in the susceptibility described above, differences dependent on the seasons in which the intoxication took place were also observed. Insects intoxicated in summer were less susceptible to pyrethroids than those intoxicated in spring.
