Hemiptera / Aphids / Mealybugs
Hemiptera /hɛˈmɪptərə/ (Latin hemipterus (“half-winged”)) or true bugs are an order of insects comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, bed bugs and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of sucking mouthparts.[3] The name "true bugs" is often limited to the suborder Heteroptera.[4] Many insects commonly known as "bugs", especially in American English, belong to other orders; for example, the lovebug is a fly[5] and the May bug and ladybug are beetles.[6]
Most hemipterans feed on plants, using their sucking and piercing mouthparts to extract plant sap. Some are hematophagous, while others are predators that feed on other insects or small invertebrates. They live in a wide variety of habitats, generally terrestrial, though some species are adapted to life in or on the surface of fresh water. Hemipterans are hemimetabolous, with young nymphs that somewhat resemble adults. Many aphids are capable of parthenogenesis, producing young from unfertilised eggs; this helps them to reproduce extremely rapidly in favourable conditions.

Abstract,Pest Management in Horticultural Ecosystems, 2010 Soil ameliorants, botanicals, chemical insecticides and fungal bio-agents were screened against banana root mealybug, Geococcus spp. Among the soil ameliorants, application of sodium silicate and calcium oxide at the time of planting...
- Scale insects and mealybugs are ubiquitous in managed landscapes. Although they are most commonly managed in the landscape on ornamental plants, this group of insects can also be damaging pests of warm season turfgrasses. To date, little research has investigated management strategies for these...
- It’s human nature to ignore what you don’t see. Why worry about something if you can’t see it? As growers, you may notice the plant is stunted and not growing well. Until you take the plant out of the pot and look at the root system, then the wax associated with root mealybug becomes noticeable....

1991-01-01 Biological control of the cassava mealybug involved the classical approach, from foreignexploration, biological studies, mass rearing, and release to monitoring and impact studies. The special attention given to quanfity observations on all trophic levels in a holistic approach transformed the...

In many habitats ants form a major part of the arthropod fauna found on vegetation, and recent studies have shown that the abundance and diversity of ant–plant associations is particularly remarkable in the tropical region. For instance, one-third of the plant species in a Panamanian forest...

Abstract, Proceedings - Biological Sciences, 2007 Interactions between ants and honeydew-producing hemipteran insects are abundant and widespread in arthropod food webs, yet their ecological consequences are very poorly known. Ant–hemipteran interactions have potentially broad ecological effects,...
