Registro de Plantas Hospedeiras (Cactaceae) e de Nova Forma de Disseminação de Diaspis echinocacti (Bouché) (Hemiptera: Diaspididae), Cochonilha-da-Palma-Forrageira, nos Estados de Pernambuco e Alagoas

Abstract

-Opuntia ficus-indica Mill. and Nopalea cochenillifera (L.) Lyons (Cactaceae) are alternative food sources for cattle in drought areas of the Northeastern Region of Brazil. Diaspis echinocacti (Bouché) is the unique pest of these Cactacea species and it was previously detected on the following native host plants: Cereus jamacaru DC., Melocactus sp., Opuntia dillenii Haw. and O. inamoena K. Schum. The new record of native hosts are Cereus gounellei (Weber) Luetzelb., C. squamosus Gërke. and the exotic C. hildemannianus K. Schum., from drought areas; Pereskia grandifolia Haw. and Epiphyllum oxypetalum Haw., native species from tropical forest used as ornamental plants. D. echinocacti has not infested O. monacantha Haw. in the field and in laboratory bioessays. The dissemination of the neonate scale insect transported on the body surface of the predators Chilocorus nigrita (Fabricius) and Zagreus bimaculosus (Mulsant) Coccinellidae: Chilocorinae) was registered for the first time.

Suitability of Two Prey Species for Development, Reproduction, and Survival of Tenuisvalvae notata (Coleoptera: Coccinellidae)

“…In South Africa, C. nigrita occasionally feeds on young mealybugs, and in the laboratory it sometimes feeds on young Planococcus citri (Risso) (Pseudococcidae), but not on the adults (Samways 1984). In northeastern Brazil, C. nigrita was first recorded in 1983 in Recife, state of Pernambuco (Samways 1989) and was observed preying on Diaspis echinocacti (Bouché) (Hemiptera: Diaspididae) infesting several cacti species in the states of Alagoas and Pernambuco (Lima & Gama 2001). Also, 1st-instars (crawlers) of this mealybug were phoretic on C. nigrita adults, which contributed to the spread of this pest (Lima & Gama 2001).…”

EFEITO DOS ATRIBUTOS QUÍMICOS DO SOLO EM DEPRESSÕES E DESPRENDIMENTO DE PLACAS NAS CASCAS EM INDIVÍDUOS DE Copaifera reticulata DUCKE EM UMA FLORESTA MANEJADA EM MOJÚ- PARÁ

“…Com o despertar para o uso forrageiro, foi sendo introduzida no Nordeste brasileiro e disseminada por ondem do governo. Seu cultivo foi introduzido do Piauí a Bahia, tratandose assim de primeiro trabalho governamental de difusão da cultura (LIMA et al, 2001;OLIVEIRA, 2016).…”

Production of Spineless Cactus in Brazilian Semiarid

“…The spineless cactus only aroused interest as feed in Pernambuco State and Alagoas State in 1902 [5]. In early twentieth century, after the drought of 1932, order of government began to spread the spineless cactus [8], realizing that the litle established plantations were insistently searched for catle, goats and sheep that ate. Thus, the plant began to be used by animal breeders [6].…”
