  • Evaluation of Intercropping and Tobacco Leaf Extract for Management of
           Fruit Borer (Helicoverpa armigera) and Some Associated Beneficial Insects
           on Tomato in Eastern Hararghe, Ethiopia

    • Authors: Belachew Dabalo
      Abstract: Tomato production is challenged by different insect pests among these, fruit borer is the most destructing pests of tomato. To tackle these problems, the study was initiated with the objective to evaluate intercropping and tobacco extract on fruit borer and some associated beneficial insects on tomato in Eastern Hararghe. Head cabbage, common bean, onion, tobacco leaf extract and karate were used as treatments. The experiment was laid out in RCBD with four replications. From these results, significant differences were observed between treatments on larval population per plant and infestation per plant for all insect pests tested and also in population reduction. Tobacco leaf extract highly reduced the population occurrence and infestation level of fruit borer next to karate and followed by onion intercropping. The number of branches, number of fruits, and number of damaged fruits, marketable yield, non-marketable yield, and total yield also showed a significant difference (P < 0.05) among the treatments. The number of fruits per plant, marketable yield, and Total yield were the highest on onion intercrops followed by karate and tobacco extracts whereas the lowest number was observed from head cabbage intercrops. Maximum yield and yield traits were recorded on tomato onion intercropping compared to the rests of intercrops while the botanical extract comparably maximized the yields with Karate. Therefore, tomato-onion intercropping and tobacco leaf extract were used as the best alternatives to karate, the synthetic insecticides in the management of tomato fruit borer.

  • Histological Study of the Sex Ratio and Reproductive Cycle of the Mangrove
           Oyster Crassostrea tulipa (Lamarck, 1819) in the Saloum Delta (Senegal)

    • Authors: Ibrahima Thiao; Jeanne Elisabeth Diouf, Malick Diouf, Éric Tamigneaux, Jean Fall, Abdou Karim Houménou, Pierre-Olivier Fontaine
      Abstract: The mangrove oyster Crassostrea tulipa has considerable socio-economic value in Senegal, as in many other West African countries. To better understand its biology, the objective of this study was to determine the sex ratio and the evolution of gonadal development stages of oyster populations in the Saloum Delta. To this end, a monthly sampling of 30 oysters between 34.19 mm and 96.68 mm height was carried out between January 2021 and January 2022. The part of the flesh that encloses the gonads was removed and fixed using Davidson's solution. After dehydration, paraffining and inclusion of the materials, 7 μm thick sections were made using a microtome. These sections were stained with Haris’s hematoxylin and eosin and the slides were observed under an optical microscope (Olympus BX41 microscope).The results showed a predominance of females over males, with a sex ratio of 1 in 2.85. The results also revealed that reproduction was continuous over the year and that spawning was asynchronous: Individuals at the spawning stage were more frequent in the warm season. These results will contribute to a better management of natural stocks and to improve oyster farming.

  • Efficacy of Water Soaked Neem (Azadiarachta indica) Leaf Filtrate on Three
           Insect Pests on okra [Abelmoschus esculentus (L.) Moench] Plants

    • Authors: Hordzi Wisdom Harrison Kofi
      Abstract: This study investigated the efficacy of neem leaf filtrate on three insect pests of okra in a garden at Winneba, Ghana. In this experiment the garden was demarcated into two equal halves where one half was used as the experimental area whereas the other half used as the control area. Filtrate of 500g of neem leaves soaked in 40 litres of pipe born water left for two weeks was used in spraying okra plants in the experimental area while five litres of ordinary water was used to spray the control area. Ten plants from each area were selected and labelled and the number of Aphis (Aphis gosspii), Thrips (Thrips spp.) and whiteflies (Bemisia tabaci) which are common okra insect pests in the area monitored on these plants. Means calculated were compared using t-test and two-way analysis of variance at 0.05 probability. Whiteflies (Bemisia tabaci) were the most abundant (48.53%) and the differences among the total numbers for the three insect pests were significant (P<0.05). There were significant differences among the means for the control and experimental groups (F =110.15, df =1, 36; P<0.05). The findings suggest that neem leaf filtrate was effective in reducing the population of the three insect pests on okra. Therefore, neem leaf filtrate may be useful alternative in controlling Aphis gosspii, Thrips spp. and whiteflies (Bemisia tabaci) on okra.
