The effects of the cytokinin hormone kinetin on the life history traits and hemocytes of the smaller wax moth Achroia grisella F. (Lepidoptera: Pyralidae) were examined in order to better understand the physiological impacts of plant growth regulators on insects. Based on the obtained results, it was found that kinetin did not lead to significant changes in larval mortality, development time, morphological disorders and egg fertility. Female and male longevity were almost unchanged when early instars were fed with a kinetin-added diet, and it tended to be higher for males when kinetin was applied at the egg stage, especially at 5 mg/L. The weight of females decreased significantly with 25 and 3000 mg/L of kinetin and that of males with 5 mg/L. The most striking effect was a considerable decline in the number of progeny, particularly at 400 and 3000 mg/L, as compared to the control. The injection of kinetin caused noticeable decreases in the number of hemocytes in the circulation at 3 and 24 h. This work presents the first evidence that kinetin adversely affects the development and the hemocyte counts of an economically-important host species, A. grisella.

The Individual

The problem of waste processing of synthetic polymers makes scientific society look for biodestructors that can digest them. Recently there have appeared some studies that claimed that caterpillars Galleria mellonella L. can influence the integrity of synthetic polymers. In terms of evolution, this species is related to beehives and can digest bee wax. The capability of this insect to digest polyethylene is still under issue. During the research, it was analyzed how the addition of polyethylene to the artificial nutrient medium affects the biological parameters of Pyralidae when cultured in the laboratory. It was shown that adding polyethylene to the standard nutrient medium in proportions of 1/4 та 1/3 does not influence the biological parameters of the species. The viability of caterpillars and chrysalides stays within the control framework. Adding polyethylene to the artificial nutrient medium in proportions of 1/2 leads to 23% lower viability during the pupa phase. The viability of chrysalides was within control framework and their individual fertility did not differ significantly. When the artificial nutrient medium contained 3/4 of polyethylene, the viability of chrysalides decreased significantly by 61%. Increasing the quantity of polyethylene in the artificial nutrient medium led to the extinguished viability which means polyethylene cannot be digested (processed). In this case, the experiment showed a delay in the development and the population reproduction was impossible. In addition to that, the individual fertility of females decreased 6 times if compared to the control group. The development phase under the conditions when the artificial nutrient medium contained ½ of polyethylene was 30 days longer than the development phase of the control group. The sex correlation in this research was 44 % of females and 56 % of males on average. As the results demonstrated the decrease of biological parameters of Galleria mellonella species when using polyethylene, we can assert that caterpillars do not digest polyethylene but in their digestive system, they have enzymes or bacteria that can influence the integrity of polyethylene.

AbstractIn western Canada, three wax-infesting moth species are serious pests of honey bee products, Vitula edmandsae serratilineella Ragonot, Achroia grisella (F.), and Plodia interpunctella (Hübner). The latter two species are found only in the Fraser Valley of British Columbia, while the driedfruit moth (sometimes called the bumble bee wax moth), V. edmandsae, is found throughout western Canada.Three female-produced pheromone components of V. edmandsae were identified as (Z,E)-9,12-tetradecadien-1-ol, (Z)-9-tetradecen-1-ol, and (Z)-11-hexadecen-1-ol, and field tested. Pheromone baits were used in traps outdoors and in bee equipment storage facilities in the Fraser and Okanagan valleys of British Columbia. The peak indoor trapping period occurred during May in the Okanagan Valley, while catches in indoor traps in the Fraser Valley were negligible throughout the entire trapping period. Catches in outdoor traps peaked during July in both regions. Traps baited with (Z,E)-9,12-tetradecadien-1-ol, alone or in binary combination with (Z)-11-hexadecen-1-ol, were significantly more attractive to male V. edmandsae than all other treatments tested. At one apiary, cumulative moth catch from a trap line 1.0 m from hives was significantly greater than that from a trap line 4.5 m away. The results suggest that a pheromone-based monitoring and control program for V. edmandsae is feasible.
