Small hive beetles, Aethina tumida are the most devastating insect pest of honey bee (Aphis mellifera) hives (Photo 1). Both adults and larvae of small hive beetle cause direct and indirect damages to honeybees. In case of direct damage, larvae of small hive beetle directly feed on the honeybee brood, honey. pollen and destroy honeycombs. In case of indirect damage, both adults and larvae of small hive beetle spread yeast, Kodamaea ohmeri into the colony and yeast that grows on the honeycombs causes fermentation of honey, which is not suitable for human consumption or as the food for honeybees.Read More
Beneficial Steinernema carpocapsae nematodes have a potential to control tropical sod webworm, Herpetogramma phaeopteralis, one of the most damaging pests of turfgrass. Sod worms are lepidopterous insects that cause a serious damage to turfgrasses that are grown in the athletic fields, golf courses, home lawns and recreational parks. Adult moths do not cause any type of damage to turfgrass but their larval stages feed on turfgrass and reduce its aesthetic value.Read More
Entomopathogenic nematodes including Steinernema riobrave and Heterorhabditis indica were evalusted against a small hive beetle Aethina tumida Murray (Coleoptera: Nitidulidae) in the field. According to Ellis et al. (2010) both nematode species caused over 76% mortality of hive beetles. Shapiro-Ilan et al. (2010) tested efficacy of H. indica and Steinernema carpocapsae against hive beetles and demonstrated that both nematode species when applied through infected host cadavers can cause up to 78% control in hive beetles. This suggests that entomopathogenic nematodes have a potential to use as biological control agents against hive beetles. Read following papers for detail information on effect of entomopathogenic nematodes on the small hive beetles.
