Nosema spp. (NS) causes severe problems to honey bee colonies including the death of the highly infected ones. Searching for effective materials to control this parasite is very important. The objectives of this study were to identify the calendar for the prevalence of NS and other bee diseases, and to test the efficacy of three materials: diluted honey mixed with lemon juice (M1), chamomile extract mixed with sugar syrup (M2) and sutrivet mixed with sugar syrup (M3) against Nosema. To realize these objectives, diseases of brood and adult honey bees were surveyed over one year. Also, the efficacy of M1, M2 and M3 against Nosema was evaluated under field and laboratory conditions. The results showed that few diseases for immature and mature stages of honey bees were recorded. NS was detected during winter and spring in link with low temperature and high relative humidity. Under field conditions, M2 reduced the infection by 36.66% while M3 by 23.33% and finally M1 by 13.33%. In the laboratory, the highest efficacy was to M2 followed by M1 and finally M3. The three materials impacted the percentage of survived bees significantly higher than infected bees without any treatments over the experimental period. The study suggests the potential role of chamomile as a natural material to control NS.

The present study evaluated the susceptibility of field populations of Plutella xylostella and Spodoptera exigua larvae to four diamide insecticides—chlorantraniliprole, cyantraniliprole, cyclaniliprole, and flubendiamide. All the four diamide insecticides induced 100% mortality in the populations from Seongju (SJ) and Geochang (GC) when treated at a concentration recommended for P. xylostella. However, a very low insecticidal activity was observed in the population from Pyeongchang (PC) with 42.3% 3 d after treatment with chlorantraniliprole. Further, the populations of S. exigua from Cheongju (CJ), Jindo (JD), and Yeonggwang (YG) were not completely controlled by the 4 diamide insecticides. A comparison of susceptibility of S. exigua larvae to chlorantraniliprole between 2014 and 2017 showed that chlorantraniliprole induced 100% mortality in all populations in 2014, whereas a very low insecticidal activity was observed among the populations in 2017. This study can serve as a basis to control pests effectively using diamide insecticides.

This study investigated the developmental and ovipositional characteristics of Protaetia brevitarsis individuals that were fed with fermented mulberry sawdust. The developmental periods of larvae were 164.0, 73.3, and 64.8 days at 25, 28, and 30°C, respectively. The maximum larval weight was 2.94 g at 25°C, and the weight of larvae decreased as temperature increased. The average weight of female adults were 0.94, 0.51, and 0.54 g at 25, 28, and 30°C, respectively. The weight of male adults was higher than that of females. The addition of 10% or 30% wheat bran to the fermented mulberry sawdust increased larval weight. It was possible to sell larvae from 75 days after mass rearing, when the cumulative rate of larvae that were heavier than 2.5 g was approximately 75%. The average number of eggs per female was 83.2 at 25°C, and this was the highest in the 5th week. Most of the eggs (73%) were oviposited between 3 and 8 weeks after adults emergence.

Studies of immune responses in insects have focused on mechanisms that interact directly with invading microorganisms. However, few studies have examined the immune response to various metabolites produced by microorganisms after they enter the host. Here, we examined immune responses in Protaetia brevitarsis seulensis larvae induced by metabolites produced by symbiotic and pathogenic bacteria. The two types of bacteria were cultured under the same conditions. The bacteria were then removed and the remaining culture supernatant was injected into the larvae. The larvae injected with culture medium (Ch-medium) from symbiotic bacteria remained relatively healthy and did not develop an immune response, whereas more than 60% of the larvae injected with pathogen culture medium (Ec-medium) died after 150 hours and dark brown patches of melanin were observed at the injection site. This immune response was confirmed by the finding of activated lysosomes in insect granulocytes. More than 50% of lysosomes in larvae injected with pathogen culture medium were strongly stained after 12 h, but less than 5% of those injected with symbiotic culture media were stained. Therefore, it is assumed that symbiotic bacteria produce few (if any) substances that induce host immune responses.
