It is in view of the foregoing, that a damage assessment study was carried out on a 2 hectare amazionain hybrid cocoa plantation for two cocoa seasons and thereafter controlled using endosulphan to curtail an outbreak of
mirid damage in the field.
These dominance results showed the reduction in feeding competition between nontarget herbivores and target insects controlled by the Bollgard[R] technology, as a reduction in competition for food resources with target caterpillars controlled by the CrylAc toxin and the sucking herbivores like the pentatomids and
mirids. They show the importance of the knowledge of bioecology interaction between insects in an agroecosystem.
Damage by the brown cocoa
mirid is caused by the feeding activities of the nymphs and adults.
Accurate estimates of the abundance of some pests are difficult to obtain because, for instance, the small size and fast movement of thrips and the elusive behavior of green
mirids. Accurate estimates of Helicoverpa spp.
The
mirids were represented by only six species in this study as a result of the limited time directed at any specific taxa.
aestivus Bratteng), insects such as the
mirid bug (Capsodes infuscatus) prevent the development of the inflorescences in some plants.
(1998) assessed the efficacy of neem formulations for the control of jassid and brown plant hopper of rice and reported neem products were safer to predatory
mirid bug, Cyrtorhinus lividipennis and predatory spiders.
(2009) tested various concentration of Thiamethoxam against cocoa
mirid, Sahlbergella singularis Hagl.
Ten groups (23%) were positively related to precipitation (leaf-feeding Coleoptera; Aleyrodidae (Homoptera); a membracid Multireoides sp.; four gall midges (Diptera: Cecidomyiidae); predaceous thrips (Phlaeothripidae); and salticid spiders) and one (2%) showed a nonlinear response (a
mirid Parthenicus sp.
Finke & Denno (2002) studied the combined impact of two salt-marsh-inhabiting invertebrate predators, the
mirid Tytthus vagus (Heteroptera, Miridae) and the wolf spider Pardosa littoralis Banks 1896 (Araneae, Lycosidae), on suppression of their shared prey, the planthopper Prokelisia dolus (Hemiptera, Delphacidae), in simple and complex habitats.
la), and every species of perennial shrub had multiple
mirid species.
This hydration method was also better for the survival of the
mirid's nymph phase.
