Fungal ovicidal activity on Toxocara canis eggs.
BACKGROUND Visceral toxocariasis is a parasitic zoonosis caused by Toxocara canis. The prevalence of this parasite in dogs, soil contamination and the resistance of eggs increase human exposure to the disease. Moreover, the difficulties of the control measures justify the need for alternative ones. AIMS The objective of this study was to evaluate the in vitro ovicidal activity of fungi isolat...
متن کاملSelective feeding of tobacco budworm and bollworm (Lepidoptera: Noctuidae) on meridic diet with different concentrations of Bacillus thuringiensis proteins.
Laboratory experiments were conducted to evaluate the behavior of bollworm, Helicoverpa zea (Boddie), and tobacco budworm, Heliothis virescens (F.), larvae on meridic diet with different concentrations of the Cry1Ac and Cry2Ab proteins from Bacillus thuringiensis subsp. kurstaki Berliner. The proteins used in these experiments are the ones in commercially available Bollgard and Bollgard II cott...
متن کاملIn Vitro Ovicidal Activity of Nematophagous Fungus Paecilomyces lilacinus on the Eggs of Parasitic Helminths
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...
متن کاملCotton Insect Pest Management , Agreement 13 - 589 TN
1) Moth Trapping. Despite the use of Bt-transgenic cotton on over 98% of the acreage in Tennessee, bollworm and tobacco budworm still compose an important pest complex. Bollworms may cause significant economic damage to Bt cotton fields, and the bollworm/budworm can be even more damaging to non-Bt cotton. More importantly, the threat of tobacco budworm infestations results in high adoption of B...
متن کاملBollgard cotton and resistance of tobacco budworm (Lepidoptera: Noctuidae) to conventional insecticides in southern Tamaulipas, Mexico.
Insecticide susceptibility in tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), was determined for 8 yr (1991-2001) with larvae sampled from cotton in southern Tamaulipas, Mexico. Before 1996, when Bollgard cotton expressing the Cry1A(c) delta-endotoxin was introduced into the region, two important patterns were documented. The first was economically significant increases in r...
