Potrzebuję pilnej odpowiedzi. Straciłem część octanu i muszę oszczędzać. Pytanie jak w temacie. Czy można zbierać chrząszcze do alkoholu ?
Poszukałbym na forum ale kiepsko tu działa internet...

TAK! Dodaj do niego, o ile masz tam gdzieś, ocet. Najlepiej zrobić tak: przekąpać chrząszcze w wodzie z octem (50/50) (ok. 2 godziny) a potem do alkoholu 40% z octem (może być nawet pól na pół ale dałbym 1/3 octu i 2/3 wódki). Ocet rozmiękcza tkanki i zapobiega psuciu. Sam alkohol usztywni chrząszcza więc ten ocet jest do tego, żeby owad był po wyjęciu elastyczny.

Z octem sprawdzałeś? Pamiętam taką sztuczkę z jajkiem i butelką... Czy aby chityna się nie rozpuści? Jest chemicznie bardzo blisko ze skorupką jajka...

niestety takie okazy nie nadają się do analiz DNA ...

podaje metody zabijania i konserwacji różnych grup (http://bughunter.tamu.edu/additionaltips/coleoptera/):

Coleoptera

129. TIGER BEETLES, Cicindela rectilatera Chaudior and other species. Adult beetles can be collected in sandy areas during summer months with an aerial net. Some species are also attracted to lights, and some give off an odor when handled. Beetles can be killed by freezing or using a jar containing a toxicant (e.g., ethyl acetate) before being mounted on an insect pin. Although difficult to collect, larvae may be collected by feeding a long grass straw stem down the burrow, then digging down until the larva is found. When found, it can be sifted from the soil, killed in boiling water or preservative fluid (e.g., KAAD) and stored in alcohol.

130-132. GROUND BEETLES, many species. Adults can be collected at lights at night or found underneath stones and other objects on the ground. They can be killed and mounted on insect pins. Larvae may also be found underneath debris. Both stages can be collected using pit fall traps. Immature stages should be preserved in alcohol.

133. PREDACEOUS DIVING BEETLES, several species. Adult may be collected from water using a kitchen sieve or aquatic net or at night around lights. They can be killed by freezing or in a toxin-containing jar and then mounted on insect pin or card points. Larvae should be preserved in alcohol.

134. WHIRLIGIG BEETLES, Dineutus and Gyrinus spp. Adults can sometimes be collected at lights. An aquatic net may be useful to capture them but it may be difficult because of their rapid swimming behavior. Adults can be mounted on insect pins or card points. Larvae should be preserved in alcohol.

CARRION BEETLES, Necrophorus and Silpha species. Carrion beetles are generally not seen unless an effort is made to closely examine carcasses, where they are readily found along with blow fly maggots and other insects. Adults can be collected, killed by freezing or in a jar containing a toxicant and then mounted on insect pins.

135. WATER SCAVENGER BEETLES, several genera. Adults may be collected at lights. They can be killed and mounted on insect pins or card points. Larvae can be collected using a kitchen sieve or aquatic net. They should be preserved in alcohol.

138. HORNED PASSALUS BEETLES OR BESS BEETLES, Odontotaenius spp. Colonies can be found by breaking into decaying logs and stumps in wooded areas. Wood infested by these beetles is usually well decomposed and falls apart readily. Adult passalus beetles are usually covered by mites. Adults can be killed and mounted on an insect pin. Larval and pupal stages should be killed in a preservative fluid (e.g. KAAD) or boiled and then stored in alcohol.

139-141. WHITE GRUBS, MAY AND JUNE BEETLES, Phyllophaga crinita (Burmeister) and others. Adults can be easily collected around lights, killed and mounted on insect pins. White grubs are frequently encountered tilling garden soil or by sifting through soil underneath damaged turfgrass. White grubs (larvae) can be killed in a preservative fluid (e.g., KAAD) or boiled and stored in alcohol.

142. GREEN JUNE BEETLE, Cotinis nitida (Linnaeus). Grubs can be collected from the soil by hand-picking and killed in boiling water or preservative fluid, e.g., KAAD, and preserved in alcohol. Adults can be found flying in the air or can be attracted to fermented fruit baits, or from over-ripe fruits and some flowers. They can be collected in a net or beaten into a container and killed by freezing or in a jar containing a toxicant, e.g., ethyl acetate, before being mounted on insect pins.

144, 145. EASTERN HERCULES BEETLE, Dynastes tityus (Linnaeus). Grubs can be collected from the soil by hand-picking. They can be killed in boiling water or preservative fluid, e.g., KAAD, and preserved in alcohol. Adults can also be found in the soil or attracted to lights and “black light” (ultraviolet light) traps. They can be killed by freezing or in a jar containing a toxicant, e.g., ethyl acetate, and mounted on insect pins.

CARROT BEETLE, Bothynus (Ligyrus) gibbosus (De Geer). Adults can be found in the soil or attracted to lights and “black light” (ultraviolet light) traps. They can be killed by freezing or in a jar containing a toxicant, e.g., ethyl acetate, and mounted on insect pins. Grubs can be collected from the soil by hand-picking. They can be killed in boiling water or preservative fluid, e.g., KAAD, and preserved in alcohol.

146, 147. “RAINBOW SCARAB”, A DUNG BEETLE, Phanaeus vindex MacLachlan. These beetles are rarely encountered unless an effort is made to seek out and examine fresh potential larval habitats! Animal, i.e., dog, excrement is rich in insect fauna and can yield these strikingly beautiful beetles. Beetles can be collected, washed to remove debris and killed by freezing or in a jar containing a killing agent. Adults can the be mounted on insect pins.

148-150. FLAT HEADED BORERS OR METALLIC WOOD-BORING BEETLES, Chalcophora, Chrysobothris, Agrilus, and other genera. Adults can be collected in the field with a sweep net or a beating sheet held under trees or shrubs. They are best collected on the sunny side of trees in the spring. The larger specimens like Chalcophora, Chrysobothris and Buprestis can be collected on freshly cut logs by slapping your hand down on the specimen before it flies away. Adult Acmaeodera can be collected on flowers by hand or with a net. Adults can be killed by freezing or in a jar containing a toxicant, e.g., ethyl acetate, and mounted on insect pins. Never place adults in alcohol because the coloration may change. Larvae can be cut out of infested wood, killed in boiling water or preservative fluid, e.g., KAAD, and preserved in alcohol.

151, 152. CLICK BEETLES AND WIREWORMS, many species. Adults can be attracted to ultraviolet (“black”) lights or to sweet syrup smeared on trees and fence posts. They can also be collected with a sweep net from flowers, leaves and stems or by looking under bark of decaying trees and in soil. Adults can be killed and mounted on insect pins. Larvae of soil dwelling species can be attracted to small quantities of seeds or cereals placed in holes dug into the soil or found by tilling soil. Larvae of other species occur in rotting logs and mosses. They can be killed and preserved in alcohol.

153. FIREFLIES OR LIGHTNINGBUGS, several species. Lightning beetles can be collected in early summer (late May) beginning at dusk with an aerial net when
