“…Use of the predatory fly, Hydrotaea (Ophyra) aenescens, which is commercially available in several northern European countries, presents a breakthrough in the indoor control of the housefly, Musca domestica [21]. Small flies such as Mutilla glossinae are important parasites of tsetse and are promising BCAs against the tsetse fly [22].…”

“…The African dung beetles are well adapted to cattle faeces and compete with fly larvae for food. Furthermore, the rapid burial of dung by the beetles reduces the breeding habitats for the flies [21]. The scarab beetle (Scarabaeus sacer), also referred to as sacred scarab among ancient Egyptians, was famous for its habit of rolling balls of dung along the ground depositing them in its burrows.…”

“…Another bacterium, Streptomyces avermitilis, produces toxins collectively called "avermectins" which are highly effective against several invertebrates from the classes Insecta, Arachnida and Nematodes [21]. Streptomyces griseolus has been shown in the laboratory to be able to control the trematode liver fluke, Fasciola gigantica, the causative agent of Fasciolosis [75].…”

“…The lizard stomach may contain as many as 2.5-15 ticks/ stomach. However, because there are few lizards near the bird nest, their effect on the tick population may be limited [21]. The Australian gecko Gehydra dubia and the exotic Asian house gecko Hemidactylus frenatus have been observed to prey on mosquitoes; in the laboratory, they have been observed to prey more on female mosquitoes and are therefore a promising tool for the biological control of malaria [28].…”

Parasites (ectoparasites or endoparasites) are a major cause of diseases in man, his livestock and crops, leading to poor yield and great economic loss. To overcome some of the major limitations of chemical control methods such as rising resistance, environmental and health risks, and the adverse effect on non-target organisms, biological control (biocontrol) is now at the forefront of parasite (pests) control. Biocontrol is now a core component of the integrated pest management. Biocontrol is defined as "the study and uses of parasites, predators and pathogens for the regulation of host (pest) densities". Considerable successes have been achieved in the implementation of biocontrol strategies in the past. This chapter presents a review of the history of biocontrol, its advantages and disadvantages; the different types of biological control agents (BCAs) including predators, parasites (parasitoids) and pathogens (fungi, bacteria, viruses and virus-like particles, protozoa and nematodes); the effect of biocontrol on native biodiversity; a few case studies of the successful implementation of biocontrol methods and the challenges encountered with the implementation of biocontrol and future perspectives.

This work evaluated the in vitro bio-control action of actinomycetes isolated from Egyptian soil against Fasciola gigantica eggs. In this respect, the identified Streptomyces griseolus was the best parasite-control agent which gave the highest mortality percent applying three methods; the first method was the application of the grown bacterial disks with the eggs at zero time on the medium (2% w/v water-agar) and incubated for 21 days (75.5% mortality), the second method was the incubation of the bacterial disks using the same medium for 5 days before eggs inoculation, after 21 days of incubation the mortality percent was 80.8%. The application of the third method showed a good effect by using all bacterial culture filtrates. S. griseolus filtrate which had the highest lytic enzyme and proteolytic activities reached 2.0 and 660.7 U/ml, respectively, gave the highest mortality (95.5%) of F. gigantica eggs compared to the other bacterial filtrates. The crude culture filtrate and the diluted culture filtrate (1.33 fold) of S. griseolus gave the highest mortality percent against the parasite´s eggs (95.8 and 94.5%, respectively) compared to the higher diluted filtrates. The culture filtrate of S. griseolus grown on two different media and its partially purified enzyme (precipitated by 60% ammonium sulfate) were tested for their proteolytic activity and inhibitory effect against F. gigantica eggs. Medium no. 2 showed the highest proteolytic activity (1030.3 and 1138.1 U/ml) for the crude and the partially purified enzyme, respectively. While the highest inhibitory effect reached 97.6 and 89.9%, respectively. Finally, the application of crude enzyme filtrate was better than the partially purified one. Streptomyces griseolus was proved as a potential biological control agent for this helminth.
