The coconut bug Pseudotheraptus wayi Brown (Hemiptera: Coreidae) is polyphagous and may be regarded as the main heteropteran pest of avocado, litchi, guava and mango.

Integrated control of the coconut bug, Pseudotheraptus Wayi (Brown) in Zanzibar by Stefan Oswald Download PDF EPUB FB2

Pseudotheraptus wayi, a new genus and species of coreid (Hemiptera) injurious to coconuts in East Africa. Bulletin of Entomological Research, Bruwer IJ, While it is evident that the coconut bug can dam-age a signifi cant portion of exportable fruit, important aspects regarding the control of this pest, such as ear-ly warning, monitoring, as well as potential biological control alternatives, are currently still lacking.

The fol-lowing trials were therefore designed to address some these Size: KB. A stable population of 30 bugs/ha was calculated to cause damage to the fourth cluster in 30% of the trees present, corresponding to 15% damaged coconuts in the infested clusters.

Ants of the genus Oecophylla were found on many palms infested by Pseudotheraptus sp. and were calculated to give 95% control of the pest. as their generalist nature, stink bugs and particularly the coconut bug Pseudotheraptus wayi (Hemiptera: Coreidae) are not easy to control. They are generally K-selected, which means they produce relative low numbers of progeny but the likelihood of offspring to reach adulthood is high.

They are also strong com. SincePseudotheraptus sp. (almost certainly P. wayi Brown) has caused considerable damage to coconut palms in the Ivory Coast. The bug is briefly described and also the nature of the injuries caused by it on flowers and fruits.

The population dynamics of Integrated control of the coconut bug sp. were studied in detail, and the paper contains sections on the relationship between population size, degree of Cited by: The coconut stink bug Pseudotheraptus wayi (Hemiptera: Coreidae) is increasingly becoming a major problem in the subtropical growing regions of South Africa.

This is because it has a wide host range of commercial plants. The widespread use of insecticides to control these pests has created several repercussion pests. The destructive capability of P. wayi in pecan orchards in Mpumalanga province, South Africa, is well known and contributes significantly towards kernel damage (Joubert and Neethling, ).

Nymphs and adults can cause damage and many nuts are attacked in the early water stage of development, before the shells harden.

The coconut bug (Pseudotheraptus wayi) is a pest of coconut and other important crops that is not found in the Pacific. The coconut nutfall bug (Amblypelta cocophaga) is widespread in Fiji and also found in Papua New Guinea and the Solomon Islands. Coconut bug Pseudotheraptus wayi Symptoms Damged and/or aborted flowersd; sunken necrotic lesions and scars on nuts; young nuts may exude gum (gummosis) and die; many nuts fall from tree; adult insect is a brown-red with well-developed wings; nymphs are brown-red or green in color with long antennae and feed at the calyx of the nut.

The coconut bug, Pseudotheraptus wayi Brown (Heteroptera: Coreidae), is a major pest of a wide range of economically important crops in Eastern and Southern Africa.

The suitability of French beans, Phaseolus vulgaris L. (Fabales: Fabaceae) as an alternative food for mass rearing of P. wayi was determined by elucidating its development, survival, and reproduction on French bean pods in the Cited by: 5. (±59 stink bugs/month). The Friedenheim trial site was similarly infested because stink bugs ( B.

Adult coconut bug (Pseudotheraptus wayi) The coconut bug (Pseudotheraptus wayi) is the most important pest of coconuts in East Africa. A related species of coconut bug, Pseudotheraptus devastans, causes similar damage to coconuts in West Africa.

Adult bugs are brown in colour and to cm long. They lay eggs singly on the flowers or young. The coconut bug, Pseudotheraptus wayi Brown (Heteroptera: Coreidae), is a polyphagous pest of economically important crops as well as wild plants in eastern and southern Africa.

The coconut bug, Pseudotheraptus wayi Brown (Hemiptera: Heteroptera: Coreidae), is a serious pest of a number of crops in Eastern and Southern Africa. Both adults and nymphal stages are destructive because they suck sap from their hosts.

The identity of the pest is currently based exclusively on the description of adults. This paper describes eggs and instars of P. wayi, with the goal to. Biology of the coconut bug Pseudotheraptus wayi on French Beans. Description of pre-adult stages of the coconut bug, Pseudotherapthus wayi.
