Structure of nectaries of Malus sylvestris (L.) Mill.
Acta Agrobotanica, 2012 The structure of floral nectary of Malus sylvestris was examined using light and scanning electron microscopy. Nectaries in M. sylvestris flowers were situated on the adaxial surface of the receptacle, between the style and the base of filaments.

Revista Chilena de Entomología, 2022 Almost all reduviids are predators; however, recent observations have shown that certain reduviids, particularly members of tribe Harpactorini (Harpactorinae) may be associated with specific plants as a strategy of predation and complementary nectarivory.

Floral nectar production and carbohydrate composition and the structure of receptacular nectaries in the invasive plant Bunias orientalis L. (Brassicaceae) [PDF]
, 2015 The data relating to the nectaries and nectar secretion in invasive Brassicacean taxa are scarce. In the present paper, the nectar production and nectar carbohydrate composition as well as the morphology, anatomy and ultrastructure of the floral ...

Numerical cognition in bees and other insects [PDF]
, 2016 The ability to perceive the number of objects has been known to exist in vertebrates for a few decades, but recent behavioral investigations have demonstrated that several invertebrate species can also be placed on the continuum of numerical abilities ...

Sticky Exudates on the Inflorescences of \u3ci\u3eCirsium Discolor\u3c/i\u3e (Asteraceae) and \u3ci\u3ePenstemon Digitalis\u3c/i\u3e (Scrophulariaceae) as Possible Defense Against Seed Predators [PDF]
, 2018 From 1982 through 1987, I investigated whether sticky exudates released by Cirsium discolor and Penstemon digitalis in their inflorescences provide defense against seed predators. I tested two hypotheses: 1: Exudates directly deter seed predators, and 2:
