Studies of Insects and Rat Feeding on the Cones and Seeds in Masson Pine Seed Orchard

  • Received Date: 1996-04-01
  • There are 21 species of insects and rat feeding on the cones and seeds in masson pine seed orchard, Contarinia sp., Ernobius sp., Dioryctria yiai Mutuura et Munroe, Retinia cristata(Walsingham), Gravitarmata margarotana(Hein.), Dioryctria rubell Hampson and Rattus niviventer Hodgson are the most harmful insects and rat.The damage order and degree of main cone and seed insects and rat were observed according to the law of reproductive development laws of population distribution and population succession were studied.The results show that the ratio of its larval population quantity is the same as the ratio of male inflorescence and 2 year old cone quantity.According to the ecological characteristics of masson pine seeds, the control expriments are conducted.The paper proposed that the methods of integrated pest management of main cone and seed insects and rat:1.Clearing forestland in and around the orchard;2.Picking damaged cones to kill the insects;3.Screening clones which are resistant to cone and seed insect pests in masson pine seed orchard;4.In the overwintering stage, control main cone and seed insect pests by using insecticides.

Abstract: There are 21 species of insects and rat feeding on the cones and seeds in masson pine seed orchard, Contarinia sp., Ernobius sp., Dioryctria yiai Mutuura et Munroe, Retinia cristata(Walsingham), Gravitarmata margarotana(Hein.), Dioryctria rubell Hampson and Rattus niviventer Hodgson are the most harmful insects and rat.The damage order and degree of main cone and seed insects and rat were observed according to the law of reproductive development laws of population distribution and population succession were studied.The results show that the ratio of its larval population quantity is the same as the ratio of male inflorescence and 2 year old cone quantity.According to the ecological characteristics of masson pine seeds, the control expriments are conducted.The paper proposed that the methods of integrated pest management of main cone and seed insects and rat:1.Clearing forestland in and around the orchard;2.Picking damaged cones to kill the insects;3.Screening clones which are resistant to cone and seed insect pests in masson pine seed orchard;4.In the overwintering stage, control main cone and seed insect pests by using insecticides.
