Do non-diapausing insects respond to different photoperiods: Spodoptera littoralis?

Article in Press

Photoperiod is a great factor in determining the developmental pattern (continued development vs. suspended development, i.e, diapause) of many insect pests. The cotton leaf worm, Spodoptera littoralis (Boisd.) is non-diapaused insect. Knowledge about how developmental pathway of S. littoralis responds to photoperiod is necessary for mass rearing of the pest and its parasitoids and may suggest new control management. The...

Entomological and Transmission Risk Indices of Bancroftian Filariasis Vectors after Community wide Long lasting Insecticide-treated bed net (LLIN) Intervention trials in Ebonyi State, Nigeria

Article in Press

Bancroftian filariasis in Nigeria is endemic with 22.1% of the population at risk of infection. The main mosquito genera implicated with the transmission are Anopheles and Culex. To compare the infectivity rates and transmission potentials after long - lasting insecticide - treated bed net (LLIN) intervention, we conducted study on the vectors between the high transmission (rainy) and the low transmission (dry) seasons....

A comparison of the effectiveness of the aqueous extracts of milkweed, castor bean and fennel in the biocontrol of root-knot nematode in tomato

Article in Press

A study was conducted to find out the effect of three plant aqueous extracts against root-knot nematode (Meloidogyne javanica). In laboratory assays eggs and second-stage juveniles of M. javanica were exposed to aqueous extracts from leaves of milkweed (Calotropis procera), castor bean (Ricinus communis) and seeds of fennel (Foeniculum vulgare). The result of the laboratory experiment showed that all the extracts increased...

Experimental Analysis of Ecomomic Action Level of Tomato Leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) on Tomato Plant under Open Field

Article in Press

Tuta absoluta is measured as a key pest of tomato both in the field and under greenhouse conditions. It is causing heavy economic impact by larval which feeding leaves and fruits. Information on tomato leafminer economic injury levels (EILs) and economic thresholds (ETs) is relatively limited. Studies were conducted during 2015 to 2017 to determine EILs and ETs on open field is required for more effective management. The...

Biological aspects and predation of Pygidicrana v-nigrum Serville, 1839 against the Mediterranean fly

Article in Press

The biological development and quantification of Pygidicrana v-nigrum consumption was evaluated taking as prey the immature stages of Ceratitis capitata. The dermapterous insect, when ingesting C. capitata larvae, reached its nymphal period, on average, at 228 days. The lowest nymphal viability of P. v-nigrum occurred in its 1st instar when fed with larvae, reaching a value of 85%. The food provided did not influence the...
