| Abstract/Contents: | "Belonolaimus longicaudatus is an ectoparasitic nematode with a wide host range and considerable damage potential. Embryonic development of the sting nematode was monitored on water agar plates at temperatures between 20°C and 30°C. Initial cell cleavage occurred within 1-2 hours at each temperature tested. At 20°C, the development to the blastula and gastrula stage required at least 2 days and 4 days, respectively, whereas at 28°C development to the gastrula stage was completed within 2 days. B. longicaudatus completed its embryogenic development in 3-11 days. The first-stage larvae were fully developed after 2-7 days. The first molt to second-stage larvae was initiated in the egg and was completed at hatching. The rate of development was nearly linear between 20°C and 30°C. At 32°C, the average development rate began to decline and ceased at 34°C. The lower threshold temperature for development was estimated to be 13.1°C by back projection of the linear regression line to the intercept of the temperature axis. The minimal thermal time requirement for embryogenesis, determined as the reciprocal of the slope, was approximately 64.3 degree days." |
