Dispersal, Infectivity and Sex Ratio of Early- or Late-Emerging Infective Juveniles of the Entomopathogenic Nematode Steinernema carpocapsae.
Differences in activity between infective juveniles (IJ) of the entomopathogenic nematode Steinernema carpocapsae that emerged directly from cadavers onto either a sand or agar substrate compared with those emerging from a cadaver into water and then being placed on the same substrate are known to occur. Differences between S. carpocapsae IJ that emerged directly from a cadaver vs. those that e...
متن کاملEnergy Metabolism and Survival of the Infective Juveniles of Steinernema carpocapsae under Oxygen-Deficient Conditions.
Energy metabolism and its relation to survival of the infective juveniles (IJ) of S. carpocapsae under anaerobic and oxygen-deficient conditions were studied by monitoring changes in survival rate, levels of key energy reserve materials, oxygen consumption, and respiratory quotient (RQ). The effects of various factors on the survival of IJ under anaerobic conditions were also investigated. Unde...
متن کاملSimple In Vivo Production and Storage Methods for Steinernema carpocapsae Infective Juveniles.
Methods are described for standardized in vivo production, rapid harvest, and storage, in a concentrated form, of infective juveniles of the entomopathogenic nematode, Steinernema carpocapsae Mexican strain Kapow selection. Nematodes were stored in nematode wool configurations, consisting of mats of intertwined infective juveniles. Freshly harvested nematodes are readily available in adequate q...
متن کاملLocation of the Phasmids on Infective Juveniles of Steinernema glaseri.
Scanning electron microscopy revealed the location of the phasmids on infective juveniles of Steinernema glaseri. The phasmids are located about 40% of the tail length posterior to the anus and are at or near the same level. Instead of being in the center of the lateral fields, they are located just ventral to the lateral fields, or interrupting the ventral-most lateral ridge. The phasmids were...
متن کاملEffects of Insecticides on Movement, Nictation, and Infectivity of Steinernema carpocapsae.
Movement, nictation, and infectivity of Steinernema carpocapsae strain All were compared for ensheathed (EnJ) and desheathed (DeJ) infective juveniles exposed to the insecticides acephate, dichlorvos, methomyl, oxamyl, or permethrin. Nematode response to various solutions included normal sinusoidal movement, uncoordinated motion, twitching, convulsion or formation of a pretzel shape, an inactiv...
