Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

The karyotype of Bemisia tabaci (Hemiptera: Aleyrodidae)

open access: yesBulletin of Entomological Research, 1998
Whiteflies of the Bemisia tabaci (Gennadius) group are a major and increasing problem for agriculture throughout the world. In particular, the appearance and rapid spread of a highly virulent new form (silver-leaf whitefly, or B-biotype; Brown et ah, 1995), and recognition that the problem involves a complex of sibling species, host races and/or ...

Evaluation of Orius laevigatus as a predator of Bemisia tabaci in Vitro

open access: yesArab Universities Journal of Agricultural Sciences, 2022
This study determined the ability of Orius laevigatus to consume different stages of Bemisia tabaci at various densities. Additionally, the use of B. tabaci as food and its effect on the life cycle parameters and female fecundity of Orius predator developmental stages were investigated. The results showed that O.

Molecular Mechanism Underlying ROS-Mediated AKH Resistance to Imidacloprid in Whitefly

open access: yesInsects
Synthetic insecticides used to control Bemisia tabaci include organophosphorus, pyrethroids, insect growth regulators, nicotinoids, and neonicotinoids. Among these, neonicotinoids have been used continuously, which has led to the emergence of high-level ...

Development and survival of Bemisia tabaci MEAM1 (Hemiptera: Aleyrodidae) on Eucalyptus genotypes

open access: yesAgricultural and Forest Entomology, EarlyView.
This study provides the first experimental evidence of the biological performance of Bemisia tabaci MEAM1 on Eucalyptus genotypes. Development time was shortest and viability highest on soybean compared with the evaluated Eucalyptus genotypes. B. tabaci MEAM1 completed its development on Eucalyptus camaldulensis and Eucalyptus urophylla × Eucalyptus ...

Dynamics of insecticide resistance in Bemisia tabaci : a case study with the insect growth regulator pyriproxyfen

open access: yes, 2002
The dynamics of pyriproxyfen resistance in Bemisia tabaci (Gennadius) have been studied intensively in cotton fields and greenhouses in Israel. High resistance to pyriproxyfen evolved one year after its introduction for use on flowers in greenhouses ...
