“…The Ouro Preto thrips are likely to be best suited for South Africa as they were sourced off the same haplotype (A) and shown to perform better on S. terebinthifolia populations in Florida compared to the Salvador thrip ( Manrique et al 2014 ). In addition to the already established agents in Hawaii and Florida, there are a number of potential biocontrol agents that are likely to be released in the near future ( Wheeler et al 2016 ), including the stem boring weevil, Apocnemidophorus pipitzi (Coleoptera: Curculionidae) ( Cuda et al 2021 ), Calophya lutea and C. terebinthifolia (Hemiptera: Calophyidae) ( Prade et al 2021 ) and Calophya latiforceps (Hemiptera: Calophyidae) ( Bhattarai et al 2017 ). These agents should be considered in South Africa and the choice of which agent to use should be guided by climatic matching ( Martin et al 2020 ) and success of establishment on the correct haplotype in Florida.…”

Uncovering the phylogeography of Schinus terebinthifolia in South Africa to guide biological control

Schinus terebinthifolia is a problematic invasive alien plant (IAP) in South Africa that is a high priority target for biological control. Biological control has been implemented in the states of Florida and Hawaii (USA), where S. terebinthifolia is also an IAP. Phylogeographic work determined that there have been multiple introductions of two lineages (haplotype A and B) into the USA. Haplotype A was introduced to western Florida and Hawaii, while haplotype B was introduced to eastern Florida. Haplotypes A and B have subsequently hybridised in Florida, resulting in novel plant genotypes. Biological control agents in the USA are known to vary in efficacies on the two different haplotypes and hybrids. This study used molecular techniques to uncover the source populations of S. terebinthifolia in South Africa using cpDNA and microsatellites. Populations from the introduced ranges in Florida (east, west and hybrids) and Hawaii were included (n = 95). All South Africa populations (n = 51) were found to be haplotype A. Microsatellite analysis determined shared alleles with western Florida and Hawaiian populations. The likely source of South African S. terebinthifolia was determined to be western Florida through the horticultural trade. These results will help guide a biological control programme to source agents that perform well on these populations in the USA. Furthermore, the presence of only one haplotype in South Africa highlights the need to ensure no further introductions of other haplotypes of the plant are made, in order to avoid similar hybridisation events like those recorded in Florida.

The aims of this research are: (1) to predict the damage of soybean pod through the mathematical model of relationship between population density of N. viridula and pod damage, (2) to predict the soybean yield through the mathematical model of relationship between population density of N. viridula and pod damage where made by modification of Reynolds Transport Theorem. This research was used Completely Randomized Design with nine treatments and each was replicated three times. The treatment were : P0 = control, P1 = 1 nymph, P2 = 2 nymphs, P3 = 3 nymphs, P4 = 4 nymphs, P5 = 1 adult, P6 = 2 adults, P7 = 3 adults, and P8 = 4 adults. The population density of pod sucking bug was the independent variable, while dependent variables were : rate of pod damage, and dry pod weigh. Analysis of mathematical modeling was made by approaching of Continuum Theory and Reynolds Transport Theorem. The results showed that : (1) Relationship between population of N. viridula and pod damages in the form of mathematical model which is used to predict the soybean pod damage has error 0,02 – 0,10%, and (2) Mathematical model where made by modification of Reynolds Transport Theorem which is used to predict the soybean yield has error 0,01 – 1,00%.
