Abstract

Parasitism research Trichogramma sp. (Hymenoptera: Trichogrammatidae) has been carried out with the aim of studying the functional response of the parasitoid Trichogramma sp. Functional response is one measure to determine the effectiveness of a predator or parasitoid as an agent in biological control, so that it can express a change in the number of preys attacked by individual predators. Temperature is one of the most important host-parasitoid interactions in functional responses. The method used in the parasitoid parasitism Trichogramma sp. on the host Corcyra sp. using four levels of egg density Corcyra sp. with two different temperature treatments (27OC and room temperature). The results show the functional response model of the parasitoid Trichogramma sp. against its host Corcyra sp. described in the type I model. Parasitization level of Trichogramma sp. showed the same results for both temperature treatments, however, it also shows differences in the speed of predation. It also showed linearity between the parasitoids Trichogramma sp. with the host Corcyra sp. Parasitism rates are still increasing, along with an increase in host density. This research can be a starting point to improve the control of Corcyra sp. using the parasitoid Trichogramma sp. in the field.

Abstract

Acne is a chronic inflammation of the human skin. One of them is caused by the activity of the oil glands that produce excess sebum to cover the pores and is exacerbated by the presence of bacterial infections, namely Staphylococcus epidermidis and Propionibacterium acnes. Silver nanoparticles (AgNPs) are one of the most widely synthesized uses of nanotechnology because they are toxic to bacterial cells so that they can be used as antibacterial agents. This study aimed for the biosynthesis effectivity against acnes bacteria. The method was using experimental research with analyze the data through ANOVA. The results showed that zeolite-impregnated AgNPs had the potential as antibacterial agents against acne-causing bacteria that had strong inhibition as evidenced by the diameter of the inhibition zone formed on Staphylococcus epidermidis and Propionibacterium acnes in the range of 11-20 mm at any given concentration used. Based on the average diameter of the inhibition zone formed, it can be seen that the largest inhibitory zone occurred at 15 mm and 20 mm AgNO3, with 18 mm in Staphylococcus epidermidis and 14.6 mm in Propionibacterium acnes bacteria respectively. This study was the first initially test the AgNPs effect to the acne’s bacteria and its further potential for anti-acnes.

Abstract

This study aims to synthesize chitosan nanoparticles - n-hexane extract of Cinnamomum parthenoxylon (CP) fruit using the ionic gelation method, to characterize them, and to determine their antifungal activity against the wood-rotting fungi Trametes versicolor and Fomitopsis palustris. Chitosan-CP extract nanoparticles were formulated with chitosan:Na-TPP:CP extract ratio of 1:1:0.5. Particle size and polydispersity index were determined using a particle size analyzer (PSA), and particles morphology was observed using a scanning electron microscope (SEM), and antifungal activity was measured using agar media. The results revealed that the average size of chitosan nanoparticles (base) was 276.9 nm, while the average size of chitosan-CP extract nanoparticles was 807.6 nm. The polydispersity index (PI) of both nanoparticles was greater than 0.7. Observations of the nanoparticles' morphology revealed that aggregation/agglomeration formed in the resulting particles. Both nanoparticles chitosan (base) and chitosan-CP extract inhibited the growth of white rot fungi (T. versicolor) more than brown rot fungi (F. palustris), as measured by the inhibitory zone.
