INTRODUCTION Toxocara canis is an ascarid parasite of the small intestine of dogs that causes visceral larva migrans in humans. METHODS With the aim of demonstrating the effectiveness of the fungus Pochonia chlamydosporia on Toxocara canis eggs under laboratory conditions, a trial was set up in Petri dishes with 2% agar-water. RESULTS There was ovicidal activity of 43.8% (p < 0.01) in the t...

The insect growth regulator, Fenoxycarb, induced various morphogenetic aberrations in Notonecta unifasciata, Anax junius and Pantala hymenaea after treatment of late nymphal stages. Most affected nymphs died while molting from nymphs to adults. Fenoxycarb is also ovicidal to young eggs of N. unifasciata. The treatment rate of 0.034 kg AI/ha fenoxycarb induced some reduction in N. unifasciata po...

Introduction: The nematophagus fungi have been suggested as an alternative way to eliminate the zoonotic helminths eggs from the environment. In the present study, we evaluated the ovicidal activity of a fungus, Paecilomyces lilacinus, recovered from a compost soil, on the eggs of parasitic helminths under in vitro condition. Methods: Water suspension of the soil samples collected from differen...

The American Academy of Pediatrics (AAP) established diagnosis and treatment guidelines for pediculosis in 2002. Ideally, diagnosis should be based on the observation of a live louse. The presence of nits is also used by many people to positively diagnose an infestation, although a nit located farther from the scalp than 1 cm is unlikely to be viable. Other material on the scalp may be mistaken...

Interspecific variations in the susceptibility of freshly and embryonated eggs of Aedes albopictus, Ae. aegypti, Ae. atropalpus and Culex pipiens were tested against three classes of insect growth regulators (IGRs) including ecdysone agonist (azadirachtin), chitin synthesis inhibitor (diflubenzuron) and juvenile hormone analog (pyriproxyfen) at 0.001, 0.01, 0.1 and 1.0ppm concentrations. Egg ha...
