“…An interesting morphological parameter used for species comparisons and taxonomic grouping is the sexual dimorphism of the basi-tarsus on the pro-and mesothoraxic legs found in D. collicola Cabrera & Cabrera Walsh [84], D. speciosa, D. viridula (Fabricius) [85], and other species in the tribes Diabroticites and Phyllectrites [86,87]. The adhesive setae found in males of some species were supposed to play a role in copulatory behaviour and male-male competition [88].…”

An overview is given on several aspects of evolutionary history, ecology, host plant use, and pharmacophagy of Diabrotica spp. with a focus on the evolution of host plant breadth and effects of plant compounds on natural enemies used for biocontrol of pest species in the group. Recent studies on each aspect are discussed, latest publications on taxonomic grouping of Diabrotica spp., and new findings on variations in the susceptibility of corn varieties to root feeding beetle larvae are presented. The further need for in-depth research on biology and ecology of the large number of non-pest species in the genus is pointed out.

“…All of the adult insects used in this bioassay were from rearing in which the larvae were fed on corn seedlings ( Figure 1A). The adult were separated by sex according to the sexual dimorphism characteristics described by De Carli (2018) and the couples were individualized in cages made of transparent acrylic jars (13 cm long × 8 cm base) inverted on Petri dish. There was a pot of glass with water in these cages, in which the petioles of the leaves of the host plant were submerged for feeding the adult insects.…”

Diabrotica speciosa is considered one of the most important agricultural pests in Latin America. Attacks various plant species including fructiferous, vegetable, cucurbit, dicotyledonous, and gramineous crops. The goal of this work was to evaluate the influence of different host plants, offered during the larval and adult stages of D. speciosa on their development, reproductive capacity, and foliar consumption. The insects were reared with corn in the larval stage and offered common bean, corn, soybean, forage turnip and wheat in the adult phase. In another essay, the larvae were reared with bean, soybean, forage turnip, corn, wheat, potato and adult stage offered only leaves of common beans to the insects. The insects reared with corn and fed on common bean leaves in the adult phase produced bigger numbers of eggs in contrast to the insects fed on other host plants. The longevity of adult specimens and the oviposition period were greater when adults of D. speciosa were fed on soybean, forage turnip, and common bean leaves, but these parameters were reduced in the insects fed on corn and wheat leaves. The viability of D. speciosa during the immature stage was greater when the larvae were fed with potato tubers or corn seedlings. However, the larvae reared on potato tubers exhibited a longer development period in contrast to larvae fed on other plants. In the foliar consumption tests, common bean leaves were preferred by adult of D. speciosa in contrast to other plants (soybean, corn and forage turnip) offered under free-choice conditions. On the other hand, in confinement conditions, common bean was preferred by insects when compared to turnip or corn leaves. The results showed that corn was the best food for the larval development of D. speciosa while common bean represented the most suitable host for the adults.

Insetos Do Brasil: Diversidade E Taxonomia

Os membros da Ordem Coleoptera são conhecidos popularmente como besouros. Diferentes famílias são conhecidas por nomes populares particulares para cada região. Com distribuição cosmopolita, a ordem constitui o grupo maior e mais diverso de organismos do reino Animal, com cerca de 380 mil espécies descritas (Lawrence & Britton 1994; Ślipiński et al. 2011), que representam cerca de 35% do total de insetos. Em termos comparativos, o número de espécies de besouros excede o de plantas vasculares ou de fungos e é cerca de 90 vezes maior que o de mamíferos. São registradas cerca de 188 famílias no Mundo. No Brasil, já foram registradas pouco mais de 33 mil espécies em 115 famílias. Estima-se que o número real de espécies existentes esteja entre 1-12 milhões de espécies no mundo (Erwin 1982), com cerca de 130 mil no Brasil. O fator mais importante no sucesso de Coleoptera parece ser a evolução dos élitros, a forte esclerosação das partes expostas do corpo, presença de criptonefrídeos e especializações relacionadas a fitofagia. O principal efeito dessas estruturas está relacionado à proteção e a melhora nos mecanismos que reduzem a perda de água (Crowson 1981).
