Response of fourth-instar larvae of Anopheles albimanus Wiedemann (Diptera: Culicidae) to food and inert particles floating at the water surface was studied. In a choice test, larvae aggregated at powdered organic materials (blood meal, liver powder, alfalfa flour and wheat flour) but not at inert materials (kaolin, chalk or charcoal). Larvae responded positively to proteins as well as some carbohydrates, but not to cellulose. Retention of larvae at food sources found by random locomotion was found to be responsible for larval aggregation. Larvae ingested food particles 6 -9 times faster than inert particles. The significance of Anopheline feeding behavior in the development of formulations of stomach toxins (bacterial agents) used in larval control is discussed. I J I J J J I lo 2o

“…With C.molestus, a single experiment was carried out with two replicates of each treatment for two fasting conditions, 3 h and 3 days. Effects on larval drinking of adenylic acid, a powerful phagostimulant of filter feeding for Cpipiens (Dadd et al, 1982), and of two colloids, agarose and methylcellulose, were examined towards the end of this work in many mainly small experiments as dictated by the availability of larvae. In these tests, glutted larvae that had fasted for 1-3 days were used.…”

“…This interpretation is reinforced by the stimulant effect on drinking in these two species (and tentatively in A.albimanm also) of low concentrations, M, of pure adenylic acid. For Cpipiens this substance is a potent phagostimulant that increases the rate of particulate ingestion during normal filter-feeding (Dadd & Kleinjan, 1982, 1985, and also aggregates larvae towards a source of the substance (Barber et al, 1982). Though no data are given in this paper, we have used the methods described by Dadd & Kleinjan (1970, 1985 to show that lo-' M adenylic acid increases the rate of particulate ingestion with all species used in this present study.…”

ABSTRACT. Drinking rates were determined with four species of freshwater mosquito larvae by colorimetric measurement of the dye ingested after groups of fourth instars were allowed access for set periods to 2% amaranth solutions. The rate of drinking for the saline‐tolerant Aedes aegypti, 309±113 nl per h per individual, was comparable with rates given in the literature for several saline‐water species, but rates for Culex quinquefasciatus, Culex molestus and Anopheles albimanus were markedly lower (167±30, 48±17 and 108±28m per h, respectively). When larvae of A.aegypti and C. quinquefasciatus were glutted with kaolin (allowed to replace all food in the gut by filter‐feeding in kaolin suspension), drinking rates were little affected at first, but after 1 day of fasting (holding in water after glutting), drinking rates were 50% lower and were reduced by a further 20% with fasting for up to 3 days. For A.aegypti, C.quinquefasciatus and C. molestus, drinking rates were approximately doubled with kaolin dispersed in the dye solution, and after fasting, were increased by up to 100% in solutions containing 0.05% of water‐soluble yeast extract. A similar phagostimulant effect of 10‐3M adenylic acid was demonstrated for A. aegypti and C. quinquefasciatus. A single experiment indicated similar stimulatory effects of kaolin and adenylic acid for, A. albimanus. With 0.01‐0.05% agarose in the dye solutions, drinking rates for A. aegypti and C. quinquefasciatus were more than doubled, and a similar though weaker effect was demonstrated for another colloid, methylcellulose. In constrast, both colloids markedly reduced the rate of drinking with A.albimanus. These findings are discussed in relation to whether drinking and filter‐feeding are necessarily coupled. The possible significance of this with respect to larvae that feed in different microhabitats, providing different levels of dissolved and colloidal nutrient organic matter, is considered. The implications of drinking rates for biotests of solubilized bacterial toxins as mosquito larvicides are noted.

A Component of Maize Pollen That Stimulates Larval Mosquitoes (Diptera: Culicidae) to Feed and Increases Toxicity of Microbial Larvicides

To explain how larval Anopheles arabiensis Patton feed effectively in the turbid water in which they frequently develop, we determined whether an extractable component of maize, Zea mays L., pollen enhances feeding by these mosquitoes. Maturing maize produces a copious amount of wind-borne pollen that is nutritious enough and produced over a sufficient period to support the development of at least one generation of anopheline mosquitoes. Larval An. arabiensis readily ingest the contents of maize pollen or the intact pollen grains themselves. An aqueous extract of maize pollen markedly accelerates the rate at which larval An. arabiensis ingest inert particles and strongly enhances the effectiveness of Bti against larval An. arabiensis. We conclude that the ability of larval anopheline mosquitoes to feed on maize pollen in turbid water is enhanced by the release from these pollen grains of a water-soluble phagostimulatory component (or components), which may be used to increase ingestion of microbial entomotoxins.
