Wild and managed bees are well documented as effective pollinators of global crops of economic importance. However, the contributions by pollinators other than bees have been little explored despite their potential to contribute to crop production and stability in the face of environmental change. Non-bee pollinators include flies, beetles, moths, butterflies, wasps, ants, birds, and bats, amon...
certain compounds of plants such as essential oils, with insecticidal properties have been considered as alternatives to chemical pesticides for pest control. this study reports the fumigant toxicity of citrus reticulata blanco (rutaceae) peel essential oils against stored-product insect pest, red flour beetle, tribolium castaneum herbst (tenebrionidae) adults. experiment was carried out at 27 ...
Each year billions of dollars are spent worldwide on insect control in agriculture [1]. Despite this expenditure, up to 40% of a crop can be lost to insect damage, particularly in developing countries [2]. Some of the most damaging insect species belong to the Lepidoptera, the second largest insect order comprised of moths and butterflies. The larval stage of moths cause major damage to an arra...
Abstract The Queensland fruit fly, Bactrocera tryoni , is an economically important pest insect of horticultural crops in Australia, damaging a wide variety fruits and vegetables. To study the B. –fruit interaction, we conducted transcriptomic investigation larvae feeding on three ripening stages tomato fruit, which had been previously shown to influence larval performance. Fruit fly survival i...
Little is known about tritrophic interactions involving seed-feeding insects, parasitoid wasps, and wild fleshy fruits. Here, we examine relationships between Pseudargyrotoza conwagana (F.) (Lepidoptera: Tortricidae), Bracon otiosus Marshall (Hymenoptera: Braconidae), and the wild privet, Ligustrum vulgare L. (Lamiales: Oleaceae), after collecting fruits in a hedgerow habitat in northwest Spain...
Some phytosanitary irradiation treatment research against tephritid fruit ßies (Diptera: Tephritidae) has used artiÞcially infested fruit with the unstated and untested assumption that the method adequately simulated a natural situation. We compare grapefruit, Citrus paradisiMacfayden, naturally infested byMexican fruit ßy,Anastrepha ludens (Loew), via oviposition until larvae reached the late ...
The importance of insects for global food crop production is starting to be well-known but the level dependence on less referenced, especially some aromatic crops. Fennel ( Foeniculum vulgare, Mill.) an mass-flowering cultivated in south France its essential oil that contains anethole. This compound and economical interest because anise flavour, which used elaborate drinks. Here, we have charac...
Ambophily (wind and insect pollination) has been reported for some genera of the typically wind-pollinated family Cyperaceae, including genus Rhynchospora. The significance wind pollination can vary, depending on local microclimatic conditions. Rhynchospora cephalotes is an ambophilous species that grow under different environmental conditions, either along forest edges or inside fragments. Thi...
Modern Neotropical rainforests are characterized by the high intensity and host specificity with which insects feed on plants. Previous studies have shown that, during middle–late Paleocene, leaves of early evolving tropical South America were heavily herbivorized insects. Yet, less attention has been given to insect damage found fossil fruits seeds, despite specialization many disseminule pred...
