I'm looking for fruit fly resistant African varieties with AI. They come up with landraces which are mostly grown for seeds and have bitter flesh. Further looking came up with this which is kind of interesting...
2. Winter Melon (Wax Gourd, Benincasa hispida)
This large Asian cucurbit develops an extremely thick, hard, waxy rind as it matures, providing excellent protection against insect penetration (including fruit flies). The waxy coating adds an extra layer of resistance. It's often stored for months due to this durable skin.
This is a link to the wiki page

Also i found that the yellow melon i spoke is the Canary
Grok has this to say about it:
Fruit Fly Resistance in Canary Melon
The melon fruit fly (Bactrocera cucurbitae, now often called Zeugodacus cucurbitae) is a major pest of cucurbits, including various melons. It prefers softer-skinned hosts like cucumbers, muskmelons/cantaloupes, and watermelons, where females can easily pierce the rind with their ovipositor to lay eggs.
Canary melon falls into the moderately susceptible category — not as heavily attacked as softer varieties, but still vulnerable, especially in areas with high fruit fly pressure. Here's why:
Rind characteristics: The rind is relatively thick and hard compared to many muskmelons, which offers some mechanical resistance (antixenosis) by making oviposition more difficult. Research on related Cucumis melo types shows that thicker, harder rinds (along with traits like pubescence or biochemical compounds) correlate with lower infestation rates.
However, it is not considered truly resistant or immune. Standard sweet melons in the inodorus group (like Canary and honeydew) are listed as hosts for B. cucurbitae, and infestation can occur, particularly on ripening or mature fruits. In tropical/subtropical regions, losses can still happen without management.
This is my (Hugo's) conclusion: So wax gourd, not sweet but most fruit fly resistant. Canary Melon, some resistance, but sweet. They're not in the same genus so crossing is very unlikely. Otherwise hybrids could be expected who have more waxy fruit fly resistant skin and sweeter. Not so lucky.
Same goes for the African landraces which are in the Citrullus type, it won't work. They have to be landraces from in the same Melo genus as Canary melon to stand a chance of hybridizing into a good tasting fruit fly resistant variety.
But i wouldn't know where to get those Melo landrace seeds in Africa. Where do you get your seeds from usually Nathanael?
