Temperature-dependent development of the two-spotted ladybeetle, Adalia bipunctata, on the green peach aphid, Myzus persicae, and a factitious food under constant temperatures [PDF]
The ability of a natural enemy to tolerate a wide temperature range is a critical factor in the evaluation of its suitability as a biological control agent.

CONTROLE QUÍMICO DO PULGÃO MYZUS PERSICAE (SULZER,1776) (HOMOPTERA-APHIDIDAE) NA CULTURA DO FUMO
RESUMO Estudou-se a ação de diferentes inseticidas sobre populações do pulgão, Myzus persicae, em lavouras de fumo da Agro Comercial Fumageira S. A., var. Sumatra, no Município de Cruz das Almas - BA. Foram realizados dois ensaios, um em dezembro de 1991

The green peach aphid, Myzus persicae, is the main virus vector in sugar beet. We examine its performance on potential winter hosts as well as the host selection and overwintering success of anholicyclic aphids in order to improve forecasting models for virus outbreaks through targeted monitoring of suitable winter hosts. Abstract Virus yellows (VY) is

A primary survey of aphid species on almond and peach, and natural enemies of Brachycaudus amygdalinus in As-Sweida, Southern Syria [PDF]
Syria is one of the biggest almond producer country in the world. Few arthropdes that live on almond are consider as pests. Aphids are one of the major pests their.

We used automated activity monitors to examine how light‐emitting diode illumination affects the daily locomotor activity of the parasitoid biocontrol agent Aphidius matricariae. We compared 4‐ to 20 h broad‐spectrum white (BSW) photoperiods, and 12 h BSW photoperiods extended with an additional 6 h of red‐blue, red‐green‐blue, or BSW light, or no ...

mTOR Complex 1 Implicated in Aphid/Buchnera Host/Symbiont Integration
Obligate nutritional endosymbioses are arguably the most intimate of all interspecific associations. While many insect nutritional endosymbioses are well studied, a full picture of how two disparate organisms, a bacterial endosymbiont and a eukaryotic ...

The effect of within-crop habitat manipulations on the conservation biological control of aphids in field-grown lettuce [PDF]
Within-crop habitat manipulations have the potential to increase the biological control of pests in horticultural field crops. Wildflower strips have been shown to increase the abundance of natural enemies, but there is little evidence to date of an ...

In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling
