Mutualism Between Ants and Honeydew-Producing Homoptera
In this review, the term "mutualism" is defined as an association between ants and other insects which is mutually beneficial without neces­ sarily implying obligate dependence or interdependence. Expand
Role of Ants in Pest Management
In view of their abundance, their stability as populations, and their feeding habits, ants have a major influence in many habitats and may be useful in pest management, but such positive attributes must be weighed against possible disadvantages. Expand
The role of biodiversity in the dynamics and management of insect pests of tropical irrigated rice—a review
P pest management of much tropical irrigated rice must be based on natural controls rarely supplemented by insecticides, and there is no evidence that a natural control-based approach, as recommended in this review, is incompatible with farmer practicability or with future developments in rice production.

The Ecology of Myzus persicae
There is a special need for the integrated control approach which will lower the numbers of the vector especially at times when viruses are spread, but biological control by natural enemies and by manipulating the host plant could also be enhanced in the crop. Expand
Distribution and dynamics of the Argentine ant Linepithema (Iridomyrmex) humile (Mayr) in relation to vegetation, soil conditions, topography and native competitor ants in Portugal
It is concluded that the dominant native C. scutellaris and P. pallidula in their favoured plantation habitats, and T. hispanicum in some arable and pasture habitats can delay or prevent spread of L. humile in soils and vegetation conditions that also suit it. Expand
Studies of the Life History and Ecology of the Ant Oecophylla longinoda Latreille
In British East Africa Oecophylla longinoda (Latr.) var. textor Santschi is locally common in the costal region. Inland it is absent from higher altitudes and from areas where there is a pronouncedExpand
Studies on the Association of the Ant Oecophylla longinoda (Latr.) (Formicidae) with the Scale Insect Saissetia zanzibarensis Williams (Coccidae).
A close association exists between the ant Oecophylla longinoda (Latr.) and the scale insect Saissetia zanzibarensis Williams, which gives absolute protection from Coccinellid predators and, although parasitism by Coccophagus spp and predation by Eublemma spp. Expand
Natural biological control of the pine processionary moth Thaumetopoea pityocampa (Den. & Schiff.) by the Argentine ant Linepithema humile (Mayr) in Portugal
1 Defoliation by larvae of the pine processionary moth, Thaumetopoea pityocampa, is negligible in stands of Pinus pinaster colonized by the Argentine ant Linepithema humile which preys fiercely onExpand
Studies on Theraptus sp. (Coreidae); the Cause of the-Gumming Disease of Coconuts in East Africa.
Theraptus sp. is widespread in the coastal region of British East Africa where it severely damages developing coconut fruits. The female may lay over 100 eggs. There are five nymphal instars and, inExpand
Population studies on the active stages of the black bean aphid, Aphis fabae Scop., on its winter host Euonymus europaeus L
Experiments using exclusion techniques provided evidence that natural enemies which attack A. fabae on E. europaeus and on summer hosts cause the common 2-year cycle of aphid abundance, which is used as sensitive indicators of later crop infestations. Expand
