Notes: Title in English: [Communication behaviors of the Neotropical mealybug Neochavesia caldasiae (Balachowsky 1957) (Pseudococcidae: Rhizoecinae) with its symbiotic ant Acropyga fuhrmanni (Forel 1914) (Formicidae: Formicinae)]. Abstract: We present several elements of the communication behavior of Neochavesia caldasiae (Pseudococcidae, Rhizoecinae) with its host ant Acropyga fuhrmanni. These insects live in symbiosis on the cocoa tree roots at Bahia, Brazil. The mealybug antennae are used as a communication organ between the two organisms, aiming to recruit the ant to be sheltered or carried to another gallery of the nest. We describe the 'appeasement boxing': the mealybug boxes the ant with its abdominal apex when it is hustled by the ant, aiming this one far from its safe place on the root.
