“…All species of the subfamily Pentatominae are plant feeders, with a similar ecology (Panizzi et al, 2000). The frequency characteristics of N. viridula vibratory signals are also similar to other Pentatominae species described so far , 2007Pavlovčič and Č okl, 2001;McBrien et al, 2002); therefore the tuning of the system and the morphological data presented in this study bear importance for the whole taxon.…”

The central processing mechanisms of vibratory signals in small plant-dwelling insects that rely primarily on substrate-borne vibratory communication are still largely unknown. To elucidate the neural mechanisms involved in vibratory signaling, the vibration-sensitive interneurons in thoracic ganglia of the southern green stinkbug, Nezara viridula, were investigated electrophysiologically by single-cell recordings and staining. Ten types of interneurons were described and divided into four categories, based on their gross morphology. The cell body of the L-shaped CG-AC neurons is located in the metathoracic neuromere of the central ganglion, and the axon ascends contralaterally. This group comprises five types of neurons differing in their fine structure and functional properties. CG-AB neurons are dorsal unpaired median (DUM) neurons with cell bodies in the mesothoracic neuromere of the central ganglion and two axons that ascend bilaterally into the prothoracic ganglion. Group CG-L includes three types of local neurons limited to the central ganglion. With ipsilateral dendritic arborizations and contralateral axonal branching, their gross morphology is similar to that of cricket omega cells. Interneuron PTG-DC, with the cell body in the prothoracic ganglion (PTG) and a contralaterally descending axon, conveys information received by the sensory organs of the front contralateral leg to the neuropil regions of the ipsilateral middle and hind legs. Based on their frequency tuning and acceleration sensitivity, the vibratory interneurons fall into two groups: the low-frequency units are tuned to 50 Hz and the middle frequency units to 200 Hz, with their acceleration thresholds at 10(-1) m/s(2) and 5 x 10(-3) m/s(2), respectively. Their function is discussed with relevance to the vibratory communication of N. viridula.

“…, 2001), whereas in two sympatric Thyanta species, this type of song (designated MS1 in these species) is produced either during calling or courtship (McBrien et al ., 2002). Analogous regularly repeated short pulses are present in H. strictus male courtship songs as echeme 2 (Pavlovič & Čokl, 2001). In harlequin bugs, the song with similar characteristics, MS3, was recorded before copulation and after the emission of the female and the first and second male songs.…”

Abstract. Males of the harlequin bug, Murgantia histrionica (Hahn), produce five different vibrational songs, whereas females produce one song. Songs differ from those of other stink bugs primarily in their species‐specific temporal characteristics. The broad band male courtship songs of M. histrionica are achieved by a combination of different frequency modulated and/or narrow band subunits, with several higher harmonic frequencies. Males rather than females initiate substrate‐borne vibrational communication, and the longer‐range calling songs found typically in other pentatomid species are lacking. Interindividual differences in song temporal and spectral characteristics are discussed. Transmission of vibrational songs through a cabbage head is more efficient along veins than along lamina. Attenuation of signals transmitted through veins is low and similar to that reported previously for plant stalks. On the leaf vein, distances between peak amplitude minima and maxima are different for the dominant and subdominant frequencies. At any distance from the vibration source, a different relationship between spectral peak amplitudes can be recorded. Resolution of these differences, together with velocity differences between signals recorded on the vein and lamina, may help small stink bugs to estimate distance and to locate each other on a plant.

“…Most of so far studied pentatominae species show similar acoustic behavior, vibratory repertoire and syntax, although some songs might be missing from the repertoire , 2001, McBrien et al 2002, McBrien & Millar 2003. A different repertoire has been found in Holcostethus strictus (Fabricius) (Pavlovcic & Cokl 2001). All stink bugs so far studied produce vibratory signals that have low frequency characteristics with dominant frequencies around 100 Hz.…”

A Comunicação Entre Insetos Através de VibraçõesRESUMO -A comunicação através de vibrações originárias do substrato tem sido reconhecida há muito tempo, mas tem recebido muito menos atenção que a comunicação através do som propagado pelo ar. Recentemente, entretanto, tem se tornado cada vez mais claro o papel crucial que sinais vibratórios desempenham na comunicação em muitos grupos de insetos, o que motivou essa revisão suscinta. Sinais vibracionais estão relacionados ao comportamento sexual, de alarme e de defesa, e são em geral usados para mediar ações coordenadas em grupo e interações sociais complexas. Para insetos pequenos esses sinais representam um custo energético mínimo, com alcance máximo, e que não são percebidos facilmente por predadores e por parasitóides em potencial. Sinais originários dos substrato são produzidos por diversos métodos e detectados por receptores presentes nas seis pernas. O comportamento de corte do percevejo verde, Nezara viridula (L.) (Hemiptera: Pentatomidae) é analisado como um modelo representativo na ilustração de alguns mecanismos importantes na comunicação vibracional em insetos. Sinais vibratórios são específicos das espécies e de sexos, os quais são produzidos durante a corte e que são adequados para serem transmitidos pelas plantas, contendo informações relevantes sobre a espécie e o sexo do organismo emissor, bem como informações de onde localizar o parceiro. O papel de sinais originados do substrato, os quais são únicos para cada espécie, faz com que os estudos em sinais vibracionais sejam uma importante ferramenta para resolver problemas taxonômicos. PALAVRAS-CHAVE: Comunicação vibracional, vibração do substrato, comportamento, Nezara viridulaABSTRACT -Communication through substrate-borne vibrations has for long been recognized but in comparison with air-borne sound it has received very little attention. However, in recent years it has become increasingly clear that vibrational signals play a crucial role in communication in many insect groups and we provide a short overview. Vibrational signals are related to sexual behavior, alarm and defensive behavior and are often used to mediate coordinated group actions and complex social interactions. For small insects they are probably the least costly and most far-reaching signals for intraspecific communication and also not easily perceived by a potential predator or parasitoid. Substrateborne signals are produced by diversed methods and detected by sensitive receptors in all six legs. The courtship behavior of the southern green stink bug Nezara viridula (L.) (Hemiptera: Pentatomidae) is taken as a representative model in illustrating some principal mechanisms of vibrational communication in insects. Species and sex specific vibrational signals produced during the courtship are well suited for propagation through plants and to transmit the relevant information about the species and sex of the sender as well as provide the directional cue for locating the mate. The role of substrate-borne signals as a part of the specifi...
