Background Ruminant dung is a highly ephemeral, patchily distributed resource, which is utilized by a diverse community of invertebrate species. This ecologically important community may be affected adversely by insecticide and endectocide residues in the faeces of treated cattle. The aim of the present work was to quantify the aggregation of the insects colonising cow-dung in cattle pastures a...
INTRODUCTION Cow dung known since long ago for its germicidal properties, used by Indian villagers to clean the house premises. As cow dung is not available easily, nowadays people have started using synthetic yellow coloured powder (Auramine-o) available easily in grocery shops locally known as "Morechap powder" in districts of Maharashtra. As the poisoning is rare, very few literatures are av...
A study of dung beetles rolling dung balls to safety reveals unexpected facets of the beetle's acquisition and use of celestial information for keeping to a straight path.
During last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. However, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. In this paper we examined dung germinating seed content, seed deposition p...
The control of ruminant gastrointestinal nematodes and ectoparasites, one of the major production health problems, are heavily reliant on the systematic and sometimes abusive use of anthelmintic drugs. Endectocides are the most frequently used drugs, having high potency against arthropods and nematodes. Their dung pat residues enhance the risk of adverse effects on non-target invertebrates and ...
Use of vermiwash extracted from vermicomposts of different combination of animal agro and kitchen wastes, is one of the effective liquid biofertilizer for growth and productivity of crops. The present study assesses that it has caused significant effect on the growth and productivity of paddy (Oryza sativa), maize (Zea mays) and millet (Penisetum typhoides) crops. The 10mg/m2 of vermiwash buffa...
Aging of bovine dung for 3-5 years under refrigeration resulted in smaller sizes of horn fly, Haematobia irritans (L.), pupae. Growth of horn fly larvae in mixtures of aged and fresh dung resulted in production of larvae and pupae stunted in proportion to the relative amount of aged dung. Reduction of size of pupae produced in aged dung was because of nutrient limitation, which was partially re...
Agricultural waste cow dung was used as feedstock for the production of a high value-added chemical levulinic acid (LA) in dilute acid aqueous solutions. A high LA yield of 338.9 g/kg was obtained from the pretreated cow dung, which was much higher than that obtained from the crude cow dung (135 g/kg), mainly attributed to the breakage of the lignin fraction in the lignocellulose structure of t...
Considering Dung’s argumentation framework and semantics, we are interested in the problem which consists in deciding whether a set of arguments is acceptable under a given semantics. We look at three approaches. The first one consists in testing whether the set satisfies an equation; In particular, we look at the equations presented in (Dung 1995; Besnard & Doutre 2004). The second approach co...
Despite the increasing rate of systematic research on scarabaeine dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae), their fossil record has remained largely unrevised. In this paper, we review all 33 named scarabaeine fossils and describe two new species from Dominican amber (Canthochilum alleni sp.n., Canthochilum philipsivieorum sp.n.). We provide a catalogue of all fossil Scarabaeinae a...
