The predators of first- and second-instar larvae of Aedes stimulans and A. trichurus in temporary woodland pools near Belleville, Ontario, were determined mainly by use of mosquito larvae tagged with radioactive phosphorus, but in part from the presence of aedine remains found in the digestive tracts of dissected beetles. Of 428 pond animals collected from the test pools 122 were found to be radioactive above background. Among the 17 species of aquatic insects and other animals that fed on mosquito larvae, 8 species of Dytiscidae, 1 of Hydrophilidae, 1 of Limnephilidae, and 1 pond snail are regarded as important predators. Three additional species of water beetles were identified as predators from aedine remains in their digestive tracts. The abundance of the predators, and the times of occurrence of six species in relation to mosquito development, are discussed.

Long-palped Water Beetles were collected during a taxon expedition in Montenegro which involved citizen scientists, students and taxonomists. The material was collected from springs, brooks, fens and the Tara River, at altitudes between 600 m and 1450 m above sea level, using fine-meshed hand-nets and by manual checking of submerged substrates. The morphological species delimitation was supplemented and congruent with mtDNA sequences mainly obtained in the field using the newly-developed MinION-based ONTrack pipeline. The new species Hydraena dinarica Freitag & de Vries, sp. n. from Durmitor Mt. is described, illustrated and compared in detail to closely-related congeners of the H. saga d'Orchymont, 1930/H. emarginata Rey, 1885 species complex. Five additional species and female specimens of two unidentified morphospecies of the genus were also recorded in the vicinity of Durmitor National Park. New records and the first DNA barcodes for Hydraena biltoni Jäch & Díaz, 2012 (endemic to Montenegro) and H. morio Kiesenwetter, 1849 are provided. Further records of H. nigrita Germar, 1824, H. minutissima Stephens, 1829, H. subintegra Ganglbauer, 1901 and females of two unidentified morphospecies are commented upon. The resulting inter- and intraspecific genetic distances and some observations of low or zero sequence divergence between recently-diverged species of Hydraena Kugelann, 1794 are briefly discussed.

All vector control programs emphasize the use of biological control. Anisops sardea (Notonectidae: Hemiptera) and Orthetrum chrysostigma (Libellulidae: Odonata) were common in freshwater communities in Mosul. They were predators of wing-wing larvae.

Backbones consumed 9.0, 8.0, 6.7 and 6.7 of the four larval ages respectively and 5.3 virgins within 24 hours while the mantis nestled at the same time 8.7 6.7, 6.3 and 5.3 larvae of the four ages respectively and 3.3 virgins. Both predators preferred the third and fourth stages when faced with all the incomplete stages of the prey. The co-existence and synergy between predators O.chrysostigma and A.sardea increased the effectiveness of predation by 17% together. The number of prey consumed per day increased with increasing density in the predators' Search coefficient for both predators. The Orthetrum chrysostigma preferred the Hamoush larvae to the mosquito larvae while the  Anisops sardea preferred mosquito larvae to the Hamoush  larvae significantly.

Last July (1922) a species of beetle, kindly identified by Dr. G. A. K. Marshall as the Tiger beetle, Cicindela octoguttata, F., a common Tropical African species, was observed to prey on mosquito larvae at Accra, in the Gold Coast. As this habit of the beetle does not appear to have been previously observed, and as it is perhaps remarkable that it should prey on such entirely aquatic insects as mosquito larvae, the following brief note may prove of interest.

Abstract The toxic effects of an avermectin-impregnated fine plant powder (AIFP) against larval Aedes aegypti L. (Diptera: Culicidae), Culex modestus Ficalbi (Diptera: Culicidae), and Anopheles messeae Falleroni (Diptera: Culicidae), as well as selected nontarget aquatic invertebrates, were studied under laboratory conditions. The possibility of trophic transfer of avermectins (AVMs) through the food chain and their toxic effects on predaceous species fed AIFP-treated mosquito larvae was also evaluated. Among mosquitoes, Anopheles messeae were the most sensitive to AIFP, while Cx. modestus exhibited the least sensitivity to this formulation. Among nontarget aquatic invertebrates, the greatest toxicity of AIFP was observed for benthic species (larval Chironomus sp. Meigen (Diptera: Chironomidae), whereas predators (dragonflies, water beetles, and water bugs) exhibited the lowest AIFP sensitivity. AIFP sensitivity of the clam shrimp Lynceus brachyurus O. F. Muller (Diplostraca: Lynceidae), the phantom midge Chaoborus crystallinus De Geer (Diptera: Chaoboridae), and the mayfly Caenis robusta Eaton (Ephemeroptera: Caenidae) was intermediate and similar to the sensitivity of the mosquito Cx. modestus. However, these nontarget species were more resistant than An. messeae and Ae. aegypti. Solid-phase extraction of mosquito larvae treated with AIFP and subsequent high-performance liquid chromatography (HPLC) analysis of the extracts revealed an AVM concentration of up to 2.1 ± 0.3 μg/g. Feeding the creeping water bug Ilyocoris cimicoides L. (Hemiptera: Naucoridae) on the AIFP-treated mosquito larvae resulted in 51% mortality of the predaceous species. But no toxicity was observed for Aeshna mixta Latreille (Odonata: Aeshnidae) dragonfly larvae fed those mosquito larvae. The results of this work showed that this AVM formulation can be effective against mosquito larvae.

Allozyme electrophoresis was used to determine the genetic relationships amongst various populations of Lycosa alteripa, L. eyrei and L. salifodina, the three described species of wolf spider endemic to the normally dry salt lakes of southern Australia. A total of 185 individuals from 38 sites was analysed for allozyme variation at 31-35 loci. The results demonstrate the presence of two additional species of salt lake spider, one related to L. alteripa and the other related to L. eyrei. Limited population genetic analysis of the data indicates that population substructuring is common within most species, often to the finest level of geographic sampling. The data indicate that gene flow is limited in these species and reveal three instances of a similar macro-geographic pattern being displayed amongst subpopulations or taxa in central South Australia. Estimates of genetic divergence between the five taxa have also been used to provide a 'first-guess' estimate of the times of divergence for the major cladogenic events within this lineage.

Aedes Atropalpus

Predators of Aedes atropalpus (Coq.) and of other rockpool mosquitoes were investigated at Cordova Mines, Ontario, by tagging larvae with radioactive phosphorus, P32. High radiation counts showed that six species of dytiscids, two of Hemiptera, a leech, and a minnow were predators of A. atropalpus. The dytiscid Laccophilus maculosus Germ. exceeded other arthropod predators in numbers and in degrees of radioactivity. Hydra oligactis Pallas killed but did not ingest the tagged larvae. Other evidence suggested that H. oligactis inhibits breeding by capturing young larvae and paralyzing later stages. Five species of aquatic insects were predacious on larvae of Anopheles and Culex.
