Systematics of Brochymena Amyot and Audinet-Serville and Parabrochymena, new genus (Heteroptera: Pentatomidae: Halyini)

Larivière, Marie-Claude January 1990 (has links)
From the endemic New World halyine genus Brochymena, two genera are recognized. / Brochymena is redefined with 16 taxa. Four synonymies are established: B. marginella Stal = B. carolinensis (Westwood); B. pilatei Van Duzee = B. sulcata Van Duzee; B. laevigata Ruckes = B. myops Stal; B. exardentia Ruckes = B. lineata Ruckes. / Parabrochymena new genus, is erected to contain 8 taxa formerly included in Brochymena. P. inbio and P. ruckesi are newly described. P. barberi diluta is given specific rank. One synonymy is established: B. cuspidata Distant = P. haedula Stal. The status of P. aculeata remains uncertain. / Genera and species groups are described and keys to all taxa provided. As appropriate, for each species, the following are provided: original description citation, synonymies, type material, diagnosis, description, geographical distribution, chorological affinities, phylogenetic relationships, taxonomic comments, natural history, and illustrations of important structural characters. / Evolutionary relationships are discussed based on morphological, ecological, and chorological evidence.

Effectiveness of trap crops for the control of stinkbugs (Heteroptera pentatomidae) in edible Cucurbitaceae species, in Limpopo Province, South Africa

Lukhwareni, Humbulani 02 1900 (has links)
Four trap crops were tested for their ability to intercept stinkbugs (Heteroptera pentatomidae) in a cucurbit field crop at Waterpoort, Limpopo Province. The experimental trap crops were: Sunnhemp (Crotolaria juncea), okra (Abelmoschus esculentum), mustard mixture (Brassica hirta and Brassica juncea) and cowpea (Vigna unguiculata). The surveys were based on visual counts of stinkbugs from all the trap crops. Stinkbugs were collected from trap crops in a field crop trial of cantaloupe (Cucumis melo). The correlation between Brassica hirta and Brassica juncea with other trap crops had a great variance. The repeated B. hirta and B. juncea inner row experiment in 2012 interestingly lured the green stinkbug (Nezara viridula) into the cantaloupe field. Amongst the entire trap crops, stinkbugs recovered from Brassica hirta and Bassica juncea, exceeded the average of the other three trap crops. The number of adult N. viridula captured had significantly increased in March 2012 and started to drop on the B. hirta and B. juncea mixture in the first week of April. During this increase, the crops were at the seeding stage. The perimeter trap-cropping system practiced for all four trap crops varied in the attraction of stinkbugs along the perimeter of the field and inner row. B. hirta and B. juncea attracted a high number of N. viridula along the perimeter but fewer in the inner row. The B. hirta and B. juncea recorded the highest number of N. viridula in the inner rows and outer rows, compared to the other four trap crops, followed by V. ungiuculata. This study has demonstrated a significant potential of using trap crops as biological alternative for managing stinkbug pests in cucurbit crops. / Agriculture and  Animal Health / M. Sc.

The pentatomidae of South Africa

Van Heerden, P. W. (Pieter Willem),1907- 09 1900 (has links)
Thesis (MScAgric)--Stellenbosch University, 1931. / ENGLISH ABSTRACT: This thesis is presented in partial fulfilment of the requirements for the degree of MSc. Agric in Entomology. In this work an attempt has been made to gather all the available literature on the family Pentatomidae and to work out keys where possible for the genera and species recorded in South Africa . The keys for the species in either the University Collection or those of the South Africa Museum did not present much difficulty as I had access to the latter through the courtesy of Dr gill and the museum Entomologist, Dr. A. J. Hesse. I especially wish to thank Dr. Hesse for his kind assistance in connection with this work. Where I had to rely on the meagre descriptions of some entomologists it has in a few cases been impossible for me to include some of species in the keys, but I have, however, incorporated the original descriptions of the species in this work. The writer hopes, that, with the aid of the drawings and the general descriptions, the keys will be of value for the correct determination of the members of this family. The Literature available on the South African Pentatomidae is very comprehensive and scattered through various publications, some of which are hardly obtainable . This is the first attempt which has been made in this country to co-ordinate the literature on this subject and it will doubtlessly prove of value to those entomologists who have not the time or the opportunity of working through the voluminous records on this interesting group. The work has been done under the direction of Dr. T. J. Potgieter, Professor of Entomology at the Stellenbosch-Elsenberg College of Agriculture of the University of Stellenbosch and I am greatly indebted to him for advice and the kindly way in which he assisted me.
