“…In particular, the cotton stainers Dysdercus spp. (Heteroptera: Pyrrhocoridae) cause serious damage by feeding on developing cotton balls and ripe cotton seeds and transmitting fungi that develop on the immature lint and seeds (Maxwell-Lefroy, 1908;Freeman, 1947;Van Doesburg, 1968;Fuseini and Kumar, 1975;Iwata, 1975Iwata, , 1978aAhmad and Kahn, 1980;Ahmad and Schaefer, 1987;Yasuda, 1992). These pests are difficult to control by insecticide application because they are highly mobile and have many alternative wild host plants (Iwata, 1975(Iwata, , 1978a.…”

The survivability and the developmental rates of Dysdercus cingulatus when fed various cultivated and wild host plant species were compared in the laboratory. On this basis, Chorisia speciosa was regarded as a better-than-adequate host plant for D. cingulatus. Abelmoschus moschatus, A. esculentus, Hibiscus makinoi, Thespesia populnea and Gossypium arboreum were adequate, H. tiliaceus was relatively poor, and Abutilon indicum was very poor. Although D. cingulatus developed faster when fed cultivated species than when fed wild species, host plant properties such as the weight of seeds and habit (arboreal or herbaceous) could not explain the survivability and developmental rate of D. cingulatus when fed the different species. Estimations of a lower threshold temperature for the development of D. cingulatus nymphs fed with plant species except for A. indicum fell within a range of 0.5 degrees (13.9 to 14.4°C). However, the estimated total effective temperature for development varied so widely among food plant species that its value for A. indicum was more than twice that for Ch. speciosa. Developmental parameters obtained here may be applied to the design of control programs for D. cingulatus in cotton fields adjacent to or near vegetative stands containing alternative wild host plants.

“…First, Dysdercus spp. are noted for occurring in dense reproductive aggregations on their host plants (e.g., Meyers, 1927;Van Doesburg, Jr., 1968;Janzen, 1972;Fuseini and Kumar, 1975;Derr, 1980b). High density will increase the encounter rate between the sexes and, thus, the probability that an unguarded female will mate again before oviposition.…”

“…Although at this point, we cannot rule out the possibility that reptiles might become infected during predation on true bugs. indeed, such predation has been already described (Knowlton and Janes 1932, Fuseini 1975, Best and gennaro 1984.…”

Although the hindgut of some insects represents a rich source of intestinal trichomonads, their diversity is only poorly understood. the aim of the present study was to investigate the presence and abundance of intestinal trichomonads in true bugs (Heteroptera). We microscopically examined intestinal contents of more than 780 specimens belonging to 28 families of true bugs from localities in china, ghana and Papua New guinea for the presence of intestinal endosymbionts. More than 120 samples were examined also by means of Pcr using trichomonad-specific primers. We determined sequences of ssU rDNA and its region of two isolates of the genus Simplicimonas cepicka, Hampl et Kulda, 2010 and one isolate of Monocercomonas colubrorum (Hammerschmidt, 1844). Although our results showed that trichomonads are very rare inhabitants of the intestine of true bugs, two of three isolated flagellates belong to species specific for reptiles. the possibility of transmission of trichomonads between reptiles and true bugs is discussed.
