Water uptake and hatching in the potato cyst nematode, Heterodera rostochiensis, and the root knot nematode, Meloidogyne incognita.
1. The second-stage larva of the plant parasitic nematode Heterodera rostocfaensis shows very little movement while confined to the egg; on the other hand, the larva of the closely related Meloidogyne incognita is very active 2. Using interference microscopy, it is shown that the water content of the Heterodera larva increases immediately it is liberated from the egg while that of the Meloidogy...
متن کاملHatching behavior of potato cyst nematodes from the canary islands.
The present work investigated early hatching differences in naturally occuring field populations and newly reared populations of potato cyst nematodes from the Canary Islands. Hatching behavior of the two species appears to be distinct, with more juveniles hatched from G. pallida that hatch earlier and over a shorter time than G. rostochiensis. The hatching rate of 3-year-old PCN populations wa...
متن کاملSteroidal Glycoalkaloids and Molluscicidal Activity of Solanum asperum Rich. Fruits
Solanum L. (Solanaceae) is distributed mainly throughout the tropical and subtropical regions of the world and is the largest and most complex genus of the family Solanaceae. In Brazil, Solanum is represented by about 350 species. In this region, many species of Solanum are widely used in popular medicine and are commonly known as ‘yubeba’, the word derived from Tupi Guarani that refers to the ...
متن کاملSteroidal glycoalkaloids in Solanum chacoense.
Potato (Solanum tuberosum L.), a domesticated species that is the fourth most important world agricultural commodity, requires significant management to minimize the effects of herbivore and pathogen damage on crop yield. A wild relative, Solanum chacoense Bitt., has been of interest to plant breeders because it produces an abundance of novel steroidal glycoalkaloid compounds, leptines and lept...
متن کاملThe chemical composition of the cyst wall of the potato cyst-nematode, Heterodera rostochiensis.
1. Cyst walls of the potato cyst-nematode (Heterodera rostochiensis Woll.) were isolated by sieving a suspension of crushed cysts. About 12mg. of dried cyst walls was obtained from 1000 cysts. 2. The cyst walls contained mainly protein (72%, calculated from nitrogen content). On acid hydrolysis about 77% of the cyst wall went into solution. Of 19 amino acids present, proline, glycine, and alani...
