ABSTRACT. Some reproductive and ontogcnetic characteristics of Epilacltna paenulata (Germar, 1824) (Coleoptera, Coccinellidae, Epilachninae). Epilac/1Ila paenulata (Germar, 1824) was reared feeding on pumpkin leaves (Cucurbita pepo Lourt.) in laboralOlY condilions aI lemperalures of 20±O,5°C, relalive humidity of 65±O,5% and 12 hour pholoperiod. Groups of fecunded and non-fecunded females were sludied. The ovarioles showed four developing slages during egg produclion, morphologically alike for fecunded and non-fecunded females, but differing in lhe duralion lime oflhe slages. Each ovarium has 24 ovarioles on average, less lhan any olher species known into lhe genus, and ali ovario les are physiologically active at each oviposilion. The mean number of ovarioles is lower when compared wilh the olher species ofEpilachninae known. Fecunded and non-fecunded females showed a similar preoviposition period, but longer lhan any olher species known into lhe genus. The interoviposilion period is shorter among lecunded females lhan non-Iecunded and among olher species oflhe genus. The number of ovipositions and eggs per ovipositioll and lhe daily oviposilion rale are higher among lecunded females lhan non-fecunded and any olher species 01' lhe genus. Differing I"om olhe r Coccine ll idae spec ies, lhe mean eggs widlh do nOI change belween lhe first and second oviposilions. The eggs handling decrease lhe larvae viability. The difterences observed in lhe number ofeggs per oviposilion, in lhe inleroviposilion periods and lhe daily oviposilion rale between fecunded and non-fecunded lemales showed lhal male changes lhe female reprodulive capacity.

A tribo Epilachnini tem maior ocorrência na Região Andina, principalmente no centro sul do Peru, tudo indicando ser este o centro de especiação do grupo; observa-se também uma relação entre as distribuições geográficas de cucurbitáceas e solanáceas (também originárias da mesma região) e a destes insetos (GORDON 1976). Algumas espécies, mais importantes sob o ponto de vista agronômico, têm seus aspectos biológicos mais estudados, como: Epilachna varivestis Mulsant, 1850, que se alimenta das folhas de muitas variedades de feijoeiros e ocorre na 1) Contribuição número 1195 do

“…Due to infestation of epilachna beetle about 80% of plants are damaged depending on place and season for prevailing environmental conditions (Rajagopal and Trivedi, 1989). The presence of this pest is one of the limiting factors in the vegetable production causing qualitative as well as quantitative losses.…”

The study was carried out to assess the larvicidal efficacies of some indigenous plant seed extracts against epilachna beetle, Epilachna vigintioctopunctata in the laboratory of the Department of Entomology, HSTU, Dinajpur, Bangladesh. Petroleum ether and methanol solvent extracts of ata (Annona squamosa), neem (Azadirachta indica), dhutura (Datura metel) and castor (Ricinus communis) seeds were evaluated for their larvicidal properties against the larval stage of E. vigintioctopunctata. The result revealed that all the tested plant extracts had more or less insecticidal effect against the larvae and their progeny. Among the plant extracts, ata seed extract in methanol solvent performed the highest toxicity (LD 50 value 0.031 mg/insect) in larval stage after 72 hours exposure time. The effects of the extracts on fecundity, fertility and F 1 adult emergence of the epilachna beetle at doses 4.0, 2.0 and 1.0 ml/l of water including untreated control were also evaluated. The result indicated that, among the extracts, ata seed extract at maximum dose (4.0 ml/l water) showed the highest efficacy with the inhibition of total eggs (74.1%), viable eggs (80.4%) and number of emergent adult progeny (87.3%). The result also revealed that the number of eggs, number of viable eggs and F 1 progeny production decreased with the increase of doses. All the treated doses effectively reduced the epilachna beetle as compared to untreated control.
