Ovipositional Rhythms and Egg Melanization Rate of Sitona lineatus (L.) (Coleoptera: Curculionidae)

Sitona lineatus (Coleoptera: Curculionidae) Larval Feeding on Pisum sativum L. Affects Soil and Plant Nitrogen

Adults of Sitona lineatus (pea leaf weevil, PLW) feed on foliage of several Fabaceae species but larvae prefer to feed on nodules of Pisum sativum L. and Vicia faba L. Indirectly, through their feeding on rhizobia, weevils can reduce soil and plant available nitrogen (N). However, initial soil N can reduce nodulation and damage by the weevil and reduce control requirements. Understanding these ...

Dependence of Sitona lepidus (Coleoptera: Curculionidae) larvae on abundance of white clover Rhizobium nodules.

Sitona lepidus Gyllenhal (Coleoptera: Curculionidae) was first recognized in New Zealand pastures in the Waikato in March 1996 (Barratt et al., 1996). In Europe and North America, the species is considered to be a significant pest of clovers (Barratt et al., 1996 and references therein). However, white clover Trifolium repens L. (Fabaceae) is the key to profitability in New Zealand‘s pastoral i...

Does White Clover (Trifolium repens) Abundance in Temperate Pastures Determine Sitona obsoletus (Coleoptera: Curculionidae) Larval Populations?

To determine if host plant abundance determined the size of clover root weevil (CRW) Sitona obsoletus larval populations, a study was conducted over 4 years in plots sown in ryegrass (Lolium perenne) (cv. Nui) sown at either 6 or 30 kg/ha and white clover (Trifolium repens) sown at a uniform rate of 8 kg/ha. This provided a range of % white clover content to investigate CRW population establish...
