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.

Greater (Galleria mellonella L.) and lesser wax moth (Achroia grisella F.) larval feeding can cause significant damage in active honey bee (Apis mellifera L.) colonies and stored equipment. This damage may lead to significant material and financial losses. Traditional control methods use toxic chemicals that may leave residues in wax and honey and are potentially hazardous to bees and humans. In this study, we evaluated the use of a product (B401®; Vita [Europe] Ltd., Basingstoke, UK) that contains Bacillus thuringiensis Berliner, a bacterium that is not harmful to bees or humans. The main objectives of our research were to determine if B401 could be successfully applied to the midrib of foundation during its production and if combs constructed on the foundation were protected from wax moth damage. B401 significantly reduced the comb damage score that was given to combs on a scale from 0–10, with 0 equal to no damage and 10 equal to complete damage (B401 = 1.70 ± 0.39 and 0.45 ±0.16, control = 8.55 ± 0.32 and 3.80 ± 0.71) and the proportion of larvae surviving at 6 wk (B401 = 0.69 = 0.07, control = 0.95 ± 0.04). Yet, as administered in our study, the product did not eliminate all wax moth damage to combs.

Wax Moth

The greater wax moth, Galleria mellonella (Linnaeus) (Lepidoptera: Pyralidae) is the most destructive pest of honey bee, Apis mellifera Linnaeus (Hymenoptera: Apidae), throughout the world. The present study was conducted to determine the quantitative and qualitative impairing effects of the arthropod venoms, viz., death stalker scorpion Leiurus quinquestriatus (Hemprich & Ehrenberg) venom (SV), oriental Hornet (wasp) Vespa orientalis Linnaeus venom (WV) and Apitoxin of A. mellifera (AP) on the larval haemogram. For this purpose, the 3rd instar larvae were treated with LC50 of each of these venoms (3428.9, 2412.6, and 956.16 ppm, respectively). The haematological investigation was conducted in haemolymph of the 5th and 7th (last) instar larvae. The important results could be summarized as follows. Five basic types of the freely circulating haemocytes in the haemolymph of last instar (7th) larvae of G. mellonella had been identified: Prohemocytes (PRs), Plasmatocytes (PLs), Granulocytes (GRs), Spherulocytes (SPs) and Oenocytoids (OEs). All venoms unexceptionally prohibited the larvae to produce normal hemocyte population (count). No certain trend of disturbance in the differential hemocyte counts of circulating hemocytes in larvae of G. mellonella after treatment with the arthropod venoms. Increasing or decreasing population of the circulating hemocytes seemed to depend on the potency of the venom, hemocyte type and the larval instar.  In PRs of last instar larvae, some cytopathological features had been observed after treatment with AP or WV, but SV failed to cause cytopathological features. With regard to PLs, some cytopathological features had been observed after treatment with AP while both SV and WV failed to cause cytopathological features in this hemocyte type. No venom exhibited cytopathological effects on GRs, SPs or OEs.
