Natural enemy communities of aphids in alfalfa fields assessed through video recordings of sentinel cards in scenarios of contrasting aphid abundance
(2024)
The first step to better understand the relationship between natural enemy communities and pest control is to know which, when, and how frequently different natural enemies interact with their prey. In alfalfa fields of ...
Parasitism of aphids (Hemiptera: Aphididae) in relation to of alfalfa fields (Medicago sativa L.) caracteristics in Argentine Pampas
(Elsevier Science, 2012-09-15)
Alfalfa is a perennial crop and is one of the most relevant forage resources for cattle in the Argentine Pampas, with aphids (Hemiptera Aphididae) one of the main pest insects in alfalfa, being frequently attacked by a ...
Effects of habitat loss and fragmentation on the abundance and species richness of aphidophagous beetles and aphids in experimental alfalfa landscapes
(Czech Academy of Sciences, 2008)
In agro-ecosystems, habitat loss and fragmentation may alter the assemblage of aphidophagous insects, such as foliarforaging (coccinellids) and ground-foraging predators (carabids), potentially affecting intraguild ...
Foliar and ground-foraging predators of aphids associated with alfalfa crops in Chile: Are they good or bad partners?
(2007)
Carabids and coccinellids are the most abundant aphid predators in alfalfa. Depending on the amount of prey consumed, the impact of their combined effect can be additive, antagonistic, or synergistic. Laboratory trials ...

In agro-ecosystems, habitat loss and fragmentation may alter the assemblage of aphidophagous insects, Such as foliar-foraging (coccinellids) and ground-foraging predators (carabids), potentially affecting intraguild ...
Estudos bioecológicos dos afídeos da alfafa
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2013-02-08)
Aphids (Hemiptera: Aphidoidea) are insects considered as pests in many crops. Acyrthosiphon pisum, Aphis craccivora and Therioaphis trifolii f. maculata, occur often in alfalfa crops (Medicago sativa) in Brazil, causing ...
Resistance in alfalfa to Aphis craccivora Koch
(Instituto de Investigaciones Agropecuarias, 2015-12)
The cowpea aphid, Aphis craccivora Koch (Aphididae), is considered to be one of the major pests in the semiarid Pampas of Argentina and in other alfalfa (Medicago sativa L.) growing areas of the world. In the present study ...
Foliar and ground-foraging predators of aphids associated with alfalfa crops in Chile: Are they good or bad partners?
(TAYLOR & FRANCIS LTD, 2007)
Carabids and coccinellids are the most abundant aphid predators in alfalfa. Depending on the amount of prey consumed, the impact of their combined effect can be additive, antagonistic, or synergistic. Laboratory trials ...
Effect of innate preferences, conditioning and adult experience on the attraction of Aphidius ervi (Hymenoptera: Braconidae) toward plant volatiles
(Czech Academy of Sciences, 2002)
The aphid parasitoid Aphidius ervi was collected and subsequently reared on Sitobion avenae on wheat or Acyrthosiphon pisum on alfalfa. Parasitoids from both origins were exposed in an olfactometer to alfalfa or wheat ...
