Gene trees of holoparasitic plants usually show distinctly longer branch lengths than seen in photosynthetic closest relatives. Such substitution rate jumps have made it difficult to infer the absolute divergence times of parasites. An additional problem is that parasite clades often lack a fossil record.

Pollinators provide essential services for watermelon, Citrullus lanatus (Thunb.; Cucurbitales: Cucurbitaceae). Managed bumble bees, Bombus impatiens (Cresson; Hymenoptera: Apidae), have been shown to be a useful watermelon pollinator in some areas. However, the exact contribution bumble bees make to watermelon pollination and how their contribution ...

Abstract The squash bug, Anasa tristis (De Geer), is a serious pest of cucurbit crops across the United States, especially within summer squash (Cucurbita pepo L.) systems. Using their piercing sucking mouthparts, squash bugs feed on both leaf tissue and fruits, often leading to leaf necrosis, marketable fruit loss, and even plant death.

International Journal of BiosciencesCucumber (Cucumis sativus L.) is an important vegetable crop in Benin. However, several biotic factors, particularly insects, impede its production. This study aimed to evaluate the entomofaunistic diversity associated with cucumber crops. Insects were collected using moericke and pitfall traps along with a sweep net.

Abstract The biodiversity-ecosystem function (BEF) hypothesis predicts that increased richness within a trophic level supports greater resource capture. However, higher predator richness commonly found within organic compared to conventional agroecosystems does not always result in enhanced pest suppression.

Pilostyles species (Apodanthaceae) are endoparasites in stems of the plant family Fabaceae. The body comprises masses of parenchyma in the host bark and cortex, with sinkers, comprising groups of twisted tracheal elements surrounded by parenchyma that enter the secondary xylem of the host plant.

Pollination of cucumber, Cucumis sativus L. (Cucurbitales: Cucurbitaceae), by the stingless bees Scaptotrigona aff. depilis moure and Nannotrigona testaceicornis Lepeletier (Hymenoptera: Meliponini) in greenhouses [PDF]
Neotropical Entomology, 2008 When for a successful fruit development the fertilization of flowers is necessary, bees can be used as crop-pollinators in greenhouses. In the present study, we investigated the effectiveness of the stingless bees Scaptotrigona aff. depilis Moure and Nannotrigona testaceicornis Lepeletier as pollinators of cucumber plants (Cucumus sativus var. caipira)

The squash (Cucurbita maxima) phloem exudate-expressed aspartic proteinase inhibitor (SQAPI) is a novel aspartic acid proteinase inhibitor, constituting a fifth family of aspartic proteinase inhibitors. However, a comparison of the SQAPI sequence to the phytocystatin (a cysteine proteinase inhibitor) family sequences showed approximately 30% identity ...
