“…Hydropsyche and Baetis ) were not able to thrive in this condition. The range of 96‐h median lethal concentration Cu values for benthic macroinvertebrates is 0.32 to 0.54 μg/ml, with a Hydropsyche species recording a median lethal concentration value of 0.35 μg/ml at a water hardness of 210 mg/L [24]. The same species, however, showed behavioral changes due to chemical stress at 0.020 μg/ml.…”

The Boac-Makulapnit River (The Philippines) is contaminated with heavy metals primarily due to acid mine drainage (AMD). Heavy-metal levels in river water, sediment, and algae suggest that Cu is the primary contaminant in this system. Copper concentrations decrease longitudinally, indicating a contamination gradient away from the mine. This is also reflected in the whole-body metal concentration of the caddisfly Hydropsyche, wherein higher Cu levels are observed in upstream stations (677-980 microg/g in 2001). In 2002, AMD formation was observed in a midstream station resulting from the oxidation of mine tailings in floodplains deposited during a 1996 tailings spill event. This consequently increased heavy-metal concentrations locally in environmental media and is likewise perceived to have caused the absence of aquatic insects in the midstream reach. Copper concentrations also increased in Hydropsyche found downstream of the new AMD site during this year. Furthermore, even the lower Cu concentrations in Hydropsyche observed in downstream stations are still at least six times higher than the established regional baseline value (29.9 microg/g), which is calculated from samples from clean tributary streams. These tributary streams also showed higher taxa richness for aquatic insect community in riffle zones. Both biomonitoring tools suggest that the whole length of the river is severely impacted. Rehabilitation projects will be underway next year; therefore, such monitoring programs will truly be beneficial when gauging river habitat recovery.

“…Although caddisfly larvae have become important as biomonitors of environmental pollution in situ [24,28,34] and also as test organisms in laboratory [2,4,23] and field experiments [28,35], little information is available concerning Cd kinetics in Hydropsyche larvae in particular. Spehar and coworkers [36] exposed Hydropsyche and three other insects to Cd in an intermittent‐flow system with a multichannel toxicant injection system for a period of 28 d. Timmermans and coworkers [4] exposed water mites ( Limnesia maculata ) and caddisfly larvae {Mystacides spp.)…”

“…Caddisfly larvae were selected for the study because they are important decomposers of organic matter, they are a food source for fish and birds, and they are widely distributed in nature [23]. In addition, they are relatively tolerant of many trace metals and their collection for study is simple and inexpensive [24–26].…”

“…In addition, they are relatively tolerant of many trace metals and their collection for study is simple and inexpensive [24–26]. In recent years, hydropsychid larvae in particular have been used to study the uptake and effects of various contaminants under laboratory conditions [4,23,26,27] and also as in situ biomonitors [24,28]. The members of the family Hydropsychidae that were selected for the present study live in cool or warm lotic waters and are included in the groups that spin nets.…”

The use of stable isotopes coupled with inductively coupled plasma-mass spectrometry provides a unique opportunity to investigate pathways of metals in aquatic invertebrates. In this study, the simultaneous uptake and elimination of cadmium (Cd) in stream-dwelling caddisfly (Trichoptera: Hydropsychidae) larvae was measured in laboratory experiments with stable isotopes of Cd. In one experiment, animals were exposed to low levels (0.5 microg/L) of 114Cd in filtered river water and uptake was measured for 9 d, followed by 9 d during which the larvae were exposed to either 114Cd, 113Cd, or filtered river water. In a second experiment, the initial exposure concentration of 114Cd varied from 0.1 to 1.6 microg/L for 5 d, followed by 5 d during which the larvae were exposed to the same respective levels of 113Cd. The purpose of the two experiments was to test whether or not elimination of 114Cd from Hydropsyche larvae was the same in the presence or absence of Cd in the water and also whether or not elimination rates were dependent on exposure concentration. The results indicated that elimination of Cd by Hydropsyche larvae (elimination rate constant approximately 0.21-0.24/d) in the presence of Cd in the water was the same as the depuration when no metal was present. Furthermore, the elimination rate was independent of exposure concentrations, ranging between 0.1 and 1.6 microg/L. Thus, the stable isotope tracer technique enabled the simultaneous measurement of uptake and elimination of Cd in hydropsychid larvae and may have the potential to facilitate the labeling of various compartments (e.g., water, sediment, and food) in the aquatic environment.

“…For Hydropsyche angustipennis (Curtis) (Trichoptera: Hydropsychidae), there was a significant decrease in ventilation, or abdominal undulatory movements, at 20 μg Cu l −1 , resulting in a proportional increase in other locomotory behaviors and inactivity (van der Geest et al., 1999). Concentrations ranging from 100 to 600 μg Cu l −1 caused H. angustipennis to spend very little time ventilating, and individuals were, for the most part, inactive.…”

In toxicology studies, the use of death as an endpoint often fails to capture the effects a pollutant has on disruptions of ecosystem services by changing an animal's behavior. Many toxicants can cause population extinctions of insect species at concentrations well below the EC 25 , EC 50 , or EC 90 concentrations traditionally reported from short-term bioassays. A surprising number of species cannot detect metal and metalloid contamination, and do not always avoid food with significant metal concentrations. This frequently leads to modified ingestion, locomotor, and reproductive behaviors. For example, some species show a tendency to increase locomotor behaviors to escape from locations with elevated metal pollution, whereas other insects greatly decrease all movements unrelated to feeding. Still others exhibit behaviors resulting in increased susceptibility to predation, including a positive phototaxis causing immatures to move to exposed positions. For purposes of reproduction, the inability to avoid even moderately polluted sites when ovipositing can lead to egg loss and reduced fitness of offspring. Ultimately, impaired behaviors result in a general reduction in population sizes and species diversity at contaminated sites, the exceptions being those species tolerating contamination that become dominant. Regardless, ecosystem services, such as herbivory, detritus reduction, or food production for higher trophic levels, are disrupted. This review evaluates the effects of metal and metalloid pollution on insect behaviors in both terrestrial and aquatic systems reported in a diverse literature scattered across many scientific disciplines. Behaviors are grouped by ingestion, taxis, and oviposition. We conclude that understanding how insect behavior is modified is necessary to assess the full scope and importance of metal and metalloid contamination.
