Effects of Snowdrop Lectin (Galanthus nivalis Agglutinin) Expressed in Transgenic Sugarcane on Fitness of Cotesia flavipes (Hymenoptera: Braconidae), a Parasitoid of the Nontarget Pest Diatraea saccharalis (Lepidoptera: Crambidae)
Cotesia flavipes (Cameron) is a parasitoid responsible for maintaining populations of sugarcane borer, Diatraea saccharalis (F.), below economic levels in south Texas sugarcane Þelds. Transgenic sugarcane expressing the snowdrop lectin (Galanthus nivalis agglutinin, GNA) was developed against the Mexican rice borer, Eoreuma loftini (Dyar), the primary pest of south Texas sugarcane. The potentia...
متن کاملField‐evolved resistance to Bt maize in sugarcane borer (Diatraea saccharalis) in Argentina
BACKGROUND Maize technologies expressing Bacillus thuringiensis (Bt) insecticidal proteins are widely used in Argentina to control sugarcane borer (Diatraea saccharalis Fabricius). Unexpected D. saccharalis damage was observed to Bt maize events TC1507 (expressing Cry1F) and MON 89034 × MON 88017 (expressing Cry1A.105 and Cry2Ab2) in an isolated area of San Luis Province. Diatraea saccharalis l...
متن کاملGenetic diversity analysis with RAPD linked to sex identification in the sugar cane borer Diatraea saccharalis.
Diatraea saccharalis is an insect that causes considerable losses in the sugar cane crop. Our aim was to contribute to the knowledge of the biology of D. saccharalis, with the report of DNA fragments involved in the differentiation between the male and female of this species using the RAPD sex molecular marker GyakuU-13, which is specific for the W chromosome of Bombyx mori. Another point evalu...
متن کاملMorphological regional differences of epithelial cells along the midgut in Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) larvae.
The sugarcane borer, Diatraea saccharalis Fabricius, is a pest to sugarcane and many other crops. This work aims to characterize morphological variability in the epithelial cells (columnar, goblet and regenerative) along the midgut of D. saccharalis larvae. Fragments of the midgut (anterior, middle and posterior regions) were fixed and processed by light and scanning electron microscopy. There ...
متن کاملUltrastructure of the Lyonet's glands in larvae of Diatraea saccharalis Fabricius (Lepidoptera: Pyralidae).
The Lyonet's gland is found in Lepidoptera larvae, close to the excretory duct of the silk gland. The role played by this gland is still uncertain. This work aims to describe the ultrastructure of the Lyonet's gland in Diatraea saccharalis larvae, offering suggestions regarding its possible function. The insects were reared under laboratory-controlled conditions. The glands were conventionally ...
