Hodge integral techniques are used to compute the degree 1 degenerate contributions of curves of arbitrary genus in the Gromov–Witten theory of 3-folds. In the Calabi–Yau case, the contributions are compared to related M-theoretic calculations. In the Fano case, the contributions suggest new integrality conditions.
