1983
Horak, I.G. | Biggs, H.C. | Hanssen, T.S. | Hanssen, R.E.
helminths and arthropods collected from warthogs at monthly intervals, prevalence, rainfall and temperature data, clear patterns of seasonal abundance could be determined only for Physocephalus sexalatus and Haematopinus phacochoeri

2016
Anong, C. I. N. | Akinboade, O. A. | Adediran, O. A.
There is increasing alarm and awareness about the health dangerposed by the arthropod vector causing Onchocerciasis. This study was carried out with the aim to throw more light on the prevalence of the arthropod vector, Simulun damnosum. This research enabled us toproffer preventive advice to government and citizens. In carrying out this study, villages around flowing waters were used as sample sites. The method applied was direct observation, coupled with efficientrecording. Atmospheric temperature readings were periodically taken along with the density of the insect population observed under such temperature. The same was done for relative humidity (%), solar radiation (gm-ca/cm2, lum) and luminescence (cd/m2) in relation to the insect population of available FMH at every given period (fly per man hour). Our findings showed that climate conditions influence the reproductive level and numbers of the vector. The wet season is most conducive for the arthropod vector to reproduce and multiply. The humidity is high and temperature seems to be at the average. It is during this period that greater preventive measures need to beintentionally heightened to subdue the dangerous activities of the vector.

2014

The Malaysian Pangolin (Manis javanica) is an endangered species,
but is widely hunted for its medicinal value in body parts. A total of sixteen pangolins were screened for blood protozoa and six
pangolins were confi rmed to be positive for eperythrozoonosis infection based on morphology from blood smears stained with 8% Giemsa. The causative organism, Eperythrozoon sp., with a size of 0.3 μm were observed under a compound microscope at 100× magnification on the surface of red blood cells as blue coloured dots. This is the fi rst report of Eperythrozoon infection from pangolins in Malaysia. Further identifi cation using polymerase chain reaction (PCR) is necessary to confi rm E. ovis or wenyonii,
which is uncultivatable in artifi cial media.

2022
Muhammad Sayuthi | Hasnah Hasnah
Nutmeg (Myristica fragrans Hout) is a leading commodity from Aceh Province. The high yield of nutmeg oil and its distinctive aroma makes it in demand by the world market. The production of nutmeg plants is currently decreasing due to the disturbance of nuisance organisms so that nutmeg plants get sick and die. Appropriate agro eco-management of the nutmeg system is thought to overcome these problems. Such as by conserving the diversity of arthropod communities. Information regarding the presence of arthropods in nutmeg cultivation is very limited in South Aceh District. This study investigates the abundance of arthropods in nutmeg cultivation in different vegetation to detect the causes of the decline in nutmeg production in the South Aceh district. Sampling was carried out at 2 locations with different vegetation conditions, using the determining sub-samples. Each location consisted of 200 individual nutmeg plants, and at each location, several 20 individual nutmeg plants were assigned as samples. The results showed that the total collection of arthropod populations at the location I found nine orders, namely Araneae, Coleoptera, Dermaptera, Diptera, Homoptera, Hemiptera, Hymenoptera, Isoptera, and Orthoptera. Location II found 12 orders, namely Araneae, Blattodea, Coleoptera, Dermaptera, Diptera, Embioptera, Homoptera, Hemiptera, Hymenoptera, Isoptera, Orthoptera, and Phasmatodea). The class of insects and arachnids found at these two locations is part of the Phylum Arthropoda.
