“…Meanwhile, the uniform distribution pattern occurs because all individuals in the same habitat compete for both food and shelter. The uniform distribution pattern is generated by individuals competing with one another for food and shelter [57]. These animals are separated due to fierce rivalry for food and shelter.…”

Flies cohabit with humans, particularly in areas with poor sanitation, producing health problems. Flies serve as vectors for spreading a variety of harmful bacteria, either directly or through food. This research aims to use an ex post facto approach to determine the amount of diversity and distribution patterns of flies in Gampong Jawa, Banda Aceh City, Indonesia. Furthermore, this study can be used as a reference for the sorts of diseases distributed in the community and a factor in fly population control models for the prevention of infectious diseases in the area. The parameters chosen were the diversity index and the fly distribution pattern. Based on the results obtained, the diversity index tended to be low. The moderate diversity index was reached only in clusters 2 (1.02) and 3 (1.08) in the first-day morning, cluster 2 (1.2) in the second-day morning, cluster 3 (1.18) in the morning, and cluster 4 (1.01) in the afternoon of the third-day observation. In terms of distribution pattern parameters, the results obtained for uniform and clumped distribution patterns are the same when seen from the four clusters observed. According to the findings of this study, the fly diversity index in Gampong Jawa is still low, and the distribution pattern is homogeneous and clumped. As a result, to avoid pathogen transmission, a fly control model must be developed.

“…For instance, the spatial distribution of T. limbativentris adults and nymphs in irrigated rice fields depends on the crop's phenological stage (Costa et al, 2019;Pasini et al, 2020;Pasini et al, 2021). Engel et al (2021), point out that the spatial distribution study in alternative hosts helps in pest permanent monitoring and anticipating possible outbreaks.…”

The babassou plant (Attalea speciosa Mart. Ex. Spreng, Arecaceae) is an important palm tree in the state of Maranhão, northeastern Brazil. This plant is the main arboreal component in extensive geographical areas including agricultural areas. However, limited research studies exist on its role as an alternative pest host in this region. This study investigated the occurrence of Tibraca limbativentris Stal (1860) in young babassou palm trees, the effect of abiotic factors (temperature, solar radiation and rainfall) on the number of T. limbativentris adults and postures, and this insect’s spatial arrangement during the rice crop off-season. The research team inspected young babassou plants on a monthly basis in 2012 and 2013 to collect and quantify postures and adults. They collected a total of 1418 live adults, 13 dead and ten postures of T. limbativentris. There was a significant difference between the first and the other collections of live adults carried out in 2012 and 2013. Abiotic factors including rainfall, temperature and solar radiation, had no influence on the number of adults (alive and dead) and postures. The semivariogram adjusted to the Gaussian model showed that in 2013, the spatial distribution of living adults, that had an aggregate pattern, was highly dependent on the season. However, in 2012 there was a pure nugget effect. These results imply that young babassou plants are alternative T. limbativentris hosts.

“…This pentatomid has been reported to feed on other legumes such as peanuts (Pterogyne nitens Tul. ), Solanaceae, Brassicae, Compositae species (Vivan & Degrande, 2011;Panizzi et al, 2012;Engel et al, 2021), and can be an issue in cotton plants (Soria et al, 2009;Sosa-Gómez et al, 2020). Another pentatomid of agricultural importance is Diceraeus melacanthus (Dallas, 1851), the green-belly stink bug, which preferentially feeds on maize (Zea mays L., Poaceae) and wheat (Triticum aestivum L., Poaceae), particularly in areas where soybean is followed by maize as a second crop (Chocorosqui & Panizzi, 2008;Corrêa-Ferreira et al, 2010;Panizzi et al, 2016;Sosa-Gómez et al, 2020).…”

The occurrence of these stink bugs has been favored by the adoption of cultural practices such as a no-tillage system and intensive field production throughout the year which provides a food supply and causes outbreaks of both species of stink bugs (Cordeiro & Bueno, 2021;Engel et al, 2021;Smaniotto & Panizzi, 2015).…”

Some species of the Heteroptera (Hemiptera) suborder are of great agricultural importance, mainly as pests, and their control is often necessary. The use of Bacillus thuringiensis, an entomopathogenic bacterium normally extracted from the soil and used in biological control, is an alternative to the chemical control of these insects. Mortality tests must be carried out in order to select and determine a viable toxic strain, but currently there is no validated methodology for conducting those tests. In this context, this research aimed to develop and improve a selective bioassay methodology to assess the toxic effect of B. thuringiensis Cry toxins on Diceraeus melacanthus (green-belly stink bug) and Euschistus heros (neotropical brown stink bug) nymphs. A bioassay methodology consisting of tubes and artificial diet was proposed. Bioassays with D. melacanthus and E. heros nymphs were performed incorporating Cry toxins (Cry1Aa, Cry1Ab, Cry1Ac, Cry1B, Cry1C, Cry1F, Cry1G, Cry1Ia, Cry2Ab, Cry2A, Cry2Ae, Cry4A, Cry4B, Cry10, and Cry11Aa) into their liquid diet. The artificial feeding system developed in order to carry out the stink bug mortality tests was conducted. Among the toxins tested, we can highlight 2 causing 80-85% nymphal mortality on D. melacanthus, and 4 toxins causing 90-100% nymphal mortality for E. heros after 7 days of incubation. Both species are susceptible to different Cry toxins, with emphasis on Cry2Ab and Cry4B for D. melacanthus and Cry1B, Cry1G, Cry1Ia and Cry2Ab for E. heros.
