Contact activities of Piper guineense (Schum and Thonn) Eugenia aromaticum (L). (Merril Perryl) extracts in the control Dermestes maculatus larvae infesting stored fish (Clarias gariepinus) were investigated under laboratory condition (28 ±3°C 65±5% RH). The tested by application 2.0 µL each to ten third instars using micro pipette at a concentration 6.00, 10.00 20.00% p...

This paper describes the morphology of Cucullanus pinnai pinnai parasitizing Pimelodus maculatus in the Guandu River, Brazil, based on differential interference contrast (DIC) microscopy and scanning electron microscopy (SEM), providing new morphological data about this species of parasite. Nematodes were collected between May and October 2012 from specimens of Pimelodus maculatus in the Guandu...

BACKGROUND Hearing thresholds of fishes are typically acquired under laboratory conditions. This does not reflect the situation in natural habitats, where ambient noise may mask their hearing sensitivities. In the current study we investigate hearing in terms of sound pressure (SPL) and particle acceleration levels (PAL) of two cichlid species within the naturally occurring range of noise level...

The understudied Black-tailed toad agama, Phrynocephalus maculatus maculatus, (Anderson, 1872) belongs to the Agamidae family. Iranian specimens are rare in collections and are distributed in the central and south-eastern deserts of Iran. In this research, biological studies including food habits, morphology, behaviors and habitats of these species were performed from April to September, 2013. ...

Essential oil extracted from the leaves of Myrtle, Myrtus communis L. (Myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (Tribolium confusum and Callosobruchus maculatus). The chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (GC-MS). The major oil components were α-pinene (10.4%), α- Terpineol (10.1%), linalool (9.0%...

In Peninsular Malaysia, a large proportion of malaria cases occur in the central mountainous and forested parts of the country. As part of a study to assess remote sensing data as a tool for vector mapping, we conducted entomological surveys to determine the type of mosquitoes, their characteristics and the abundance of habitats of the vector Anopheles maculatus in malaria endemic areas in Pos ...

Cowpea, Vigna unguiculata [L.] Walp. is a widely planted nutritious grain legume [1]. It is cultivated in many West African countries including Nigeria. Cowpea is a source of dietary protein, vitamins and mineral salts. It has been consumed by human since the earliest practice of Agriculture in developing countries of Africa, Asia, and Latin America [2]. The pulse beetle, Callosobruchus maculat...

Pulse beetle (Callosobruchus maculatus) is a common weevil that responsible for up to 24% of stored pulse losses. Using black gram grain storage, the efficiency carbon dioxide gas against all life stages Callosobruchus maculatus insects was tested at various concentrations and exposure times. The trials were carried out in pilot bins with capacity 25 kg. At CO2 concentration 50%, complete morta...

Callosobruchus maculatus F. (Coleoptera; Bruchidae) is one of the most important storage pests, especially in legumes, which causes significant damage many parts Iran, including east Azarbaijan province. This study aimed to isolate and identify insect-associated bacteria with this pest then evaluate capability these bacterial isolates biocontrol insect laboratory conditions. Stock culture C. wa...
