Parasitic helminths eggs released into the environment through defecation of definitive hosts are affected by various environmental factors [1]. It is believed that these eggs are also invaded and eliminated by different biological agents including fungi [2]. Nematophagous fungi are potential agents for biocontrol of helminths eggs; these fungi, divided into predators, endoparasites, and ovicid...

Abstract: There are certain saprophytic fungi in the soil able to develop an antagonistic effect against eggs of parasites. Some of these fungal species are ingested by animals during grazing, and survive in their feces after passing through the digestive tract. To identify and isolate ovicidal fungi in the feces of wild captive animals, a total of 60 fecal samples were taken from different wil...

BACKGROUND Within the framework to control mosquitoes, ovicidal, larvicidal and pupicidal activity of Annona senegalensis leaf extract and its 4 fractions against Anopheles gambiae and Culex quinquefasciatus were evaluated in the laboratory conditions. METHODS Ovicidal test was performed by submitting at least 100 eggs of mosquitoes to 125, 250, 500, 1000 and 2000 ppm concentrations, while la...

This study describes the in vitro anthelmintic activity of aqueous extracts (AE), ethyl acetate extracts (EE), flavonoid fractions (FF) and saponin fractions (SF) obtained from sisal waste (Agave sisalana) against gastrointestinal nematodes of goats. The activity of these extracts was evaluated by performing inhibition of egg hatch (EHA) and larval migration (LMI) assays. The EC(50) results of ...

Mosquito-borne diseases are a major public health concern worldwide. Plant extracts from Andrographis paniculata have anti-mosquito properties. The study evaluated the extracts' larvicidal, pupicidal, and ovicidal activities, their LC50 values were compared between two mosquito species to determine relative effectiveness in controlling populations. shows that methanol promising activities again...

Biological control using entomopathogenic fungi could be a promising alternative to chemical control. Entomopathogenic fungi, Beauveria bassiana (Balsamo) Vuillemin, Metarhizium anisopliae (Metschnikoff) Sorokin, Lecanicillium lecanii (Zimmerm.) Zare and Gams, and Paecilomyces fumosoroseus (Wize) Brown and Smith, were tested for their pathogenicity, ovicidal effect, and median lethal concentrat...

Helminthosis is one of the major problems of livestock production throughout the world, particularly in tropical and subtropical areas. Chemical control of helminths is in practice in most of the parts of the world. The problem of the development of resistance against the common chemical anthelmintics has renewed the interest in the study of medicinal plants for the development of novel anthelm...
