Description:
A case of attachment and complete engorgement of a Rhipicephalus sanguineus (Latreille, 1806) nymph on a woman with severe pain shortly before nymphal drop-off is described. The pain continued for about 2 weeks after tick removal. Apparently, this is the first documented case of human adverse reaction developed at the very last stage of engorgement of nymphal R. sanguineus. The infestation most likely took place inside the enclosed household garden in the southern area of Jerusalem where the woman took care of the plants. The importance of immature R. sanguineus ticks in attacking humans is discussed.

Description:
We observed instances of cannibalism (intraspecific predation) among intra-instar larvae of Culex pipiens Linnaeus, 1758 while performing a bioassay of Lysinibacillus sphaericus (formerly named Bacillus sphaericus) larvicide, when the larvae were exposed to the larvicide for 48 h in the absence of food. Larvae without symptoms of poisoning attacked and devoured those visibly affected. Cannibalism was more prevalent in 1st-2nd instar larvae than in 3rd-4th instar. This phenomenon should be taken into account when interpreting the results of larvicide bioassays, especially when the exposure lasts over 24 h. The necessity of creating optimal conditions for organisms tested is emphasised., Igor Uspensky and Sergei Braun., and Obsahuje bibliografii
