Abstract. Insect mouthparts are modified appendages of head segments that are adapted to exploit different food sources. This chapter describes the general mouthpart morphology of Hexapoda, introduces basic feeding types in insects, and illustrates mouthpart function. Insect mouthparts include three appendages, the paired mandibles, the paired ...

Fight the urge to "bite down" or squeeze your lips too tight on the mouth piece. Draw air through the call toward the back of your throat. Avoid popping your lips and jaws. Smooth and steady suction of air through the call is key. Remember, very little air is required to produce turkey sounds on a trumpet.

A key tool in this effort since at least the early 1950s has been the insect flight mill. Nearly 260 studies have been published using flight mills covering 214 species in 61 families and 9 orders. This review explores the methodology and technology of tethered flight in insects using flight mills. The goal is to provide the reader with a ...

Chilo suppressalis is a notorious pest that attacks rice, feeding throughout the entire growth period of rice and posing a serious threat to rice production worldwide. Due to the boring behavior and overlapping generations of C. suppressalis, the pest is difficult to control. Moreover, no rice variety with high resistance to the striped stem borer (SSB) has been found in the available rice ...

Predicting the dispersal of pest insects is important for pest management schemes. Flightmills provide a simple way to evaluate the flight potential of insects, but there are several complications in relating tetheredflight to natural flight. We used highspeed video to evaluate the effect of flightmill design on flight of the red palm weevil (Rynchophorous ferruginneus) in four variants of ...

Insect mouthparts are derived from the appendages of four of the segments forming the insect head. They surround the mouth and are external to it, unlike the condition in vertebrates in which the teeth are within the oral cavity. The basic segmental character of the mouthparts is most apparent in insects that bite off fragments of food and then chew it before ingesting it (Fig. 1).
