Mango seed weevil (Coleoptera: Curculionidae) and premature fruit drop in mangoes.

Effect of mango weevil (Coleoptera: Curculionidae) damage on mango seed viability in Tanzania.

Studies were conducted at the horticulture unit of Sokoine University of Agriculture, Morogoro, Tanzania, to assess the incidence and effect of mango weevil, Cryptorhynchus mangiferae (F.) (Coleoptera: Curculionidae), infestation on mango, Mangifera indica L., seed viability. Three polyembryo mango cultivars ('Sindano nyeusi', 'Sindano nyeupe', and 'Dodo') as well as three monoembryo mango cult...

The weevil of acerola fruits, Anthonomus tomentosus (Faust, 1894) (Coleoptera: Curculionidae), is recorded for the first time in Brazil. Samples of this insect were collected in fruits of acerola, Malpighia emarginata D.C. (Malpighiaceae), in four municipalities in the north-central region of Roraima State, in the Brazilian Amazon. Information about injuries observed in fruits infested with A. ...

Control of anthracnose (caused by Colletotrichum gloeosporioides s.l.) on mango in Senegal by fungicides and biofungicides

Mango production in the South of Senegal is exposed to intensive rainfall from late May to October, with high temperature and moisture levels. These conditions are conducive for the development of anthracnose caused by Colletotrichum gloeosporioides (sensu lato) and produce a need for adequate control measures. Anthracnose disease causes preand postharvest fruit spots, fruit rot, and premature ...

Sunflower Resistance to the Red Sunflower Seed Weevil (Coleoptera: Curculionidae)

Temporal and Geographic Variation in Predispersal Seed Predation on Hibiscus moscheutos L. (Malvaceae) in Ohio and Maryland, USA

—Seed predation has the potential to strongly reduce seed production and thereby act as a selective force on the evolution of flowering traits and other defenses against herbivory. We characterized levels of predispersal seed predation on Hibiscus moscheutos (Malvaceae) during 2001 and 2002 at four sites in Ohio and Maryland, USA. The seed predators were a weevil, Conotrachelus fissinguis (Cole...
