VIRULENCE OF ENTOMOPATHOGENIC NEMATODES (RHABDITIDA: STEINERNEMATIDAE AND HETERORHABDITIDAE) FOR THE CONTROL OF Diabrotica speciosa GERMAR (COLEOPTERA: CHRYSOMELIDAE) Virulência de nematoides entomopatogênicos (Rhabditida: Steinernematidae e Heterorhabditidae) para o controle de Diabrotica speciosa Germar (Coleoptera: Chrysomelidae)
Entomopathogenic nematodes (EPNs) are used in biological control of soil insects and show promise in the control of D. speciosa. The objective of this work was to evaluate the potential of native and exotic entomopathogenic nematode isolates in the control of D. speciosa under laboratory and greenhouse conditions. Results showed that all of EPNs caused larval mortality. The most virulent were H...
متن کاملMedicinal plant extracts on the control of Diabrotica speciosa (Coleoptera: Chrysomelidae)
The aim of this study was to evaluate the insecticidal effect of aqueous, alcoholic, and oil extracts from leaves of eight medicinal plants against Diabrotica speciosa prepared at five concentrations. The extracts that used commercial soybean oil as solvent showed the highest D. speciosa mortality due to the solvent itself, regardless of the used plants and their concentrations. Thus, commercia...
متن کاملLikelihood of multiple mating in Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae).
We evaluated the mating ability of male western corn rootworms, Diabrotica virgifera virgifera Leconte (Coleoptera: Chrysomelidae), for 20 d after initial mating, using a series of laboratory experiments. Males mated an average of 2.24 times within 10 d after their first mating and averaged 0.15 matings between days 11 and 20 after their first mating. Because estimating the mating frequency in ...
متن کاملMolecular Diagnostics of Three Diabrotica (Coleoptera: Chrysomelidae) Pest Species
A 257 bp region of the mitochondrial ND4 gene was analyzed for genetic variation in three species of corn rootworm, southern corn rootworm {Diabrotica undecim punctata howardi Barber, SCR), northern corn rootworm (D. barberi Smith and Lawrence, NCR), and western corn rootworm (D. virgifera virgifera LeConte, WCR). Nucleotide sequencing revealed 26 polymorphic sites. Genetic distances averaged 8...
متن کاملFitness of Diabrotica barberi, Diabrotica longicornis, and Their Hybrids (Coleoptera: Chrysomelidae)
Diabrotica barberi Smith & Lawrence, the northern corn rootworm, and Diabrotica longicornis (Say) (Coleoptera: Chrysomelidae), are currently recognized as closely related chrysomelid species. Hybridization has been proposed to occur between them, although the viability of hybrids has never been tested. The objective of this study was to assess life-history parameters of D. barberi,D. longicorni...
