RESUMO

The present study deals with the taxonomical analysis of the edible insects commercialized in the state of Morelos, Mexico. We have recorded two species under the order Orthoptera and four species under Hemiptera-Heteroptera. Our work revealed that grasshoppers and small hemipterans known as 'jumiles' are the two main insects sold in the markets of the state of Morelos. We also discuss insects' prices and their economic importance for the livelihood improvement of the local people connected to the edible insect trade.

RESUMO

Mopani worms are abundant in Gwanda and sporadic in Tsholotsho though the two areas have similar climatic conditions. The study sought to determine nutritional factors that could be associated with distribution of Mopani worms in these two districts. Ten sampling points in undisturbed Mopani woodlands were established in each district. Samples were collected and analysed in the lab to determine the levels of crude protein, tannin and natural detergent fibres levels in leaves and pH, Nitrates, Phosphates and Potassium levels in soil and Welch's test, Wilcoxon-Mann-Whitney, Analysis of Variance and the Bonferroni Confidence Intervals were employed to test for significance in the observed differences. Findings showed differences in tree size and leaf length whilst the differences of all other variables (non-extractible tannis, extractible tannis crude protein levels and natural detergent fibres) relating to leaf sample analysis were not statistically significant. Findings on soil sample analysis pointed out that Gwanda had higher pH, Phosphorus and Potassium levels whilst Nitrates were significantly higher in Tsholotsho. Differences in the tree sizes and leaf sizes of the samples from the two sites show that there could be host selection based on these variables.

RESUMO

BACKGROUND: Elaphrodes lactea Gaede is a highly praised edible lepidopteran insect in the Miombo forest in the DRC. Both caterpillars and pupae of this species are consumed. Following recent declines in the Miombo forest, it is crucial to investigate the rate of consumption, biological, and exploitation cycles, as well as the trade and profitability of E. lactea to develop a sustainable program for its use. METHODS: We, therefore, embarked on a survey in 10 sites located in Lubumbashi between 2011 and 2015. Information on E. lactea supply chain and harvesting period was also documented as well as the mode of selling, pricing, and other determinants of the business. Data were analyzed using R2.15.0 software and means were compared using the Fisher LSD test. RESULTS: The study revealed that E. lactea is the most preferred caterpillar and several indicators guide its exploitation. Caterpillars are available between March and April, and pupation starts in May. Harvesting starts within the household surroundings before reaching the bush, and several harvesting techniques are used. The indirect mode of trade of E. lactea is the most commonly used, with the average price/kg varying between USD2.32 (during in-season = production period for caterpillars) and USD5.24 (during dry season = off-season, mainly pupae). During the peak season of caterpillar production, the harvester's average income per day varies between USD1.6 and USD3.0 whereas it varies between USD2.2 and USD5.2 during the pupal season. Anthropogenic activities, coupled with climatic factors, constitute the main drivers affecting the availability of E. lactea. CONCLUSIONS: The study, therefore, calls on a concerted action from all stakeholders to increase awareness and the development of innovative measures for sustainable exploitation of this insect while ensuring rehabilitation of the forest through community participation.
