Insecticide and Acaricide Tests, 1989
Abstract Cotton was planted 25 May at the Texas Agricultural Experiment Station, Munday. Azinphosmethyl at 0.28 kg (AI)/ha was applied 26 Jul to eliminate predators and parasites from the plots. Plots were fertilized before planting with 112 kg nitrogen/ha and irrigated 27-29 Jul.

Ovicide, Larvicide Trials, 1989
Insecticide and Acaricide Tests, 1990Abstract A greenhouse study was conducted at the Texas A&M University Research and Extension Center in Corpus Christi, TX, to measure the efficacy of binary mixtures combining Orthene and 3 pyrethroids against cypermethrin-susceptible (S) and -resistant (R) eggs/ neonates of TBW. Treatment efficacy was evaluated on eggs obtained from

Ovicide, Larvicide Trials, 1988
Insecticide and Acaricide Tests, 1989Abstract A small-plot field study was conducted in a commercial cotton field near Austwell, Tex., to measure the effects of 6 treatments on survival of tobacco budworm eggs and freshly hatched larvae of tobacco budworm. The eggs were obtained from pyrethroid-susceptible and pyrethroid-resistant strains of tobacco budworm (ICI laboratory ...

Resistance of nematode eggs to the ovicidal activity of benzimidazoles
Research in Veterinary Science, 1977Eggs of benzimidazole-resistant Haemonchus contortus and Trichostrongylus colubriformis are resistant to the ovicidal activity of benzimidazoles. The possiblity is raised of using this as a simple screen for detection of resistance in nematodes of domesticated animals.

Fungal ovicidal activity on Toxocara canis eggs
Revista Iberoamericana de Micología, 2013Visceral 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.The objective of this study was to evaluate the in vitro ovicidal ...

In vitro and in vivo studies on the ovicidal activity of fenbendazole
Research in Veterinary Science, 1978The in vitro ovicidal activity of fenbendazole against eggs of Ostertagia ostertagi, Haemonchus contortus and Trichostrongylus colubriformis was observed using different concentrations of active principle. The optimum concentration for ovicidal activity is evidently 0.5 ppm fenbendazole.

Ovicidal effects of albendazole in human ascariasis, ancylostomiasis and trichuriasis
Annals of Tropical Medicine & Parasitology, 1985Albendazole, a broad spectrum anthelmintic, was administered as a 400 mg single dose to 20 patients harbouring Ascaris (ten cases), hookworms (four cases each of Ancylostoma duodenale and Necator americanus) and trichuriasis (ten cases). Faeces were obtained before treatment and during the following five days.

Fitness consequences of ovicide in a parasitoid wasp
Entomologia Experimentalis et Applicata, 1997AbstractOvicide, superparasitism and host rejection are alternative reproductive tactics facing female parasitoid wasps encountering an already‐parasitized host. Superparasitism is simply the addition of an egg or a clutch of eggs by the secondary parasitoid, but under ovicide the primary clutch is removed or destroyed.
